Letter from the ChairJoaquin Ruiz

Peter Coney's untimely death is theDepartment's sad news. In 1982 I read an adin EOS describing a job opening at TheUniversity of Arizona. I had just finished myPhD dissertation on the origin of tin -richrhyolites of the Sierra Madre Occidental inMexico and had based many of myconclusions on Peter Coney's suspect terranemap of Mexico and his ideas of magmatismin the western US. I could barely wait to meetthis scientist. His papers were imaginative andthought provoking. Of course, the papersreflected the man. After I got to know Peter, Iwas also struck by his humanity. Peter caredabout people. He deeply cared for his studentsand was able to transmit to them hisknowledge, his analysis and his calm. In fact,what made Peter such a remarkable individualwas his genius combined with his humanity.

Peter left us with many legacies -a legacyof great thinking of how the Earth works, alegacy of great teaching, a legacy of howthings are done in a collaborative spirit. Thisnewsletter has a few sections dedicated toPeter and in fact our science article onsediment sources in North America throughtime, by Jonathan Patchett, is the kind of studythat Peter would have enjoyed. I am pleasedto announce that an endowment has beenestablished by a generous alum creating agraduate fellowship in Peter Coney's name.

On the positive side, the Departmentcontinues to do well. In research and graduateeducation, recent polls in U.S. News andWorld Report rank our Department 7th in thecountry, up from 9th last time around. TheDepartment ranked 4th in the subspecialtiesof Tectonics /Structural Geology andSedimentology. NSF figures place us as the4th best funded department in 1998. In

Junior Ed ProgramDraws 5,000 Kids

In recognition of his outstanding classroomteaching, Bob Butler has been awarded theCollege of Science Distinguished TeachingAward. Bob consistently receives superbevaluations from students for his commitmentboth to a quality education and to the studentsthemselves. Aformidable education innovatorwithin the department, Bob has driven muchof the department's curriculum developmentand has also achieved NSF funding foreducational efforts.

Something I reflect on occasionally is thespecial culture and sense of communitywhich our department possesses regardingour teaching functions. This is a departmentin which all faculty take their teachingseriously and the department staff (in mycase primarily Norm Meader and Jo AnnOvers) provide major assistance whichallows us to teach well. There are manyexcellent instructors in this department fromwhom I have learned much about teaching.Primary examples for me are Pete Kresan,Randy Richardson, George Gehrels, MichelleHall - Wallace, and Julie Libarkin. It isparticularly noteworthy that faculty andstudents who put major effort into theirteaching are recognized within our

Kids beginthe program in an exhibit area where theytouch rocks, minerals, fossils, and dinosaurbones. They look at speciments through amicroscope, tackle an interactive geosciencescomputer program, check out a 3 -D map ofArizona and compare their height to that of a

dinosaur. Kids then fill each cup of an eggcarton with a mineral or fossil donated by rockand mining companies. Once the carton isfull, each child is teamed up with a UA studentwho helps identify the minerals and discussestheir characteristics, value and possible uses."Kids tend to be fascinated with colorful andsparkling things and with dinosaurs," says PeteKresan, faculty advisor to SESS. "It's a hook,but we try to go a lot deeper than the hook."Almost 5,000 kids were hooked this year!

dimensions is one of the greatest challengesfor beginning geoscientists. Michelle Hall -Wallace, Robert Butler and Peter Kresan wererecently funded by the Learning TechnologiesPartnership at UA to help students improvetheir visualization skills through a number ofmethods. Students in their introductorycourses will explore topographic geologicmaps using software that shows therelationship between the two dimensionalmap and the three dimensional world.Students at all levels will learn to manipulateand create digital maps using GIS, which allowsthe user to create custom maps on demand usinglarge databases of information.

In Memory of

Peter J. ConeyPeter J. Coney, 69, who retired in July

1998, died of lymphoma February 20 here inTucson.

Peter was highly respected in his field asa keen and original thinker who trailblazed anumber of important concepts (core complexes,"suspect" terranes, the accidents of plateinteractions, etc.). "We have indeed lost a giantamong us," commented Professor Greg Davisof USC upon learning of Coney's death.

Raised in Maine, Peter earned a master'sdegree in geology from the University ofMaine and a geological engineering degreefrom L'Ecole National Superieure du Petrolein France, where he carried out geologic fieldinvestigations in the French Alps. Fluent both

in French and Spanish, Peter then fulfilledmilitary obligations by working in an AmericanFriends Service Committee -United Nationsproject in community development in ruralEl Salvador, Central America.

Before starting his PhD work, Peter andhis wife Darlene next lived in Zion NationalPark, where Peter was a ranger. Here hecreated the cross section showing the relationshipbetween Bryce, Zion and the Grand Canyon.Park visitors who buy maps showing how thegeology of these famous regions correlate gohome with a piece of Peter's work.

Peter obtained his PhD degree from theUniversity of New Mexico where, the storygoes, he told his advisor he wanted tounderstand the Cordillera from Alaska to thetip of South America. Indeed Coney studiedfirst -hand the geology of the Peruvian Andes,northern Alaska, the Tasman Orogen ofAustralia, and the Pyrenees of Spain as well ashis home turf in the Southwestern UnitedStates. Through these experiences hedeveloped an intuition for geologicalprocesses that allowed him to developfundamental concepts of how the Earth works.

Peter's first faculty position was atMiddlebury College in Vermont. There he wasso popular, colleagues say, that years laterwhen his name was mentioned in a speechby UA colleague George Davis, the audiencebroke into applause. Peter had the power todo that. Peter joined the UA GeosciencesDepartment in December 1975 where hebecame the cornerstone of an influential groupin tectonics. William Dickinson later joined thisgroup to form what had to be one of the mostpowerful tectonic programs in the world.

Peter Coney recently received a Collegeof Science Career Distinguished TeachingAward. Nominating letters from colleaguescited Peter's unique perspective on themountain systems of the world and his highlyeffective teaching style combining inspirationand encouragement with high expectations

and challenges to students. He possessed achildlike ability to seek unconventionalsolutions to classic geologic problems. Peterwould often claim that he knew little ofpetrology, or detailed structural geologicanalysis, or geophysics. Then, in the nextbreath, he would pose a question to aspecialist in one of those fields which cut tothe heart of a fundamental unansweredproblem. It was well understood that Peterdid not do this as some sort of exercise inintellectual bullyism. Anyone who knew Peterwould tell you that such an act would be veryunlike this gentle person. Instead, thosepenetrating questions were evidence of adriving intellectual curiosity supported by anunusual command of the geological andgeophysical literature.

But Peter Coney was not only anextraordinary thinker and an importantcontributor to geological research. In additionto his science, he taught very popular coursesand was an unparalleled mentor to hisgraduate students. One of the traits Coney'scolleagues and students most admired himfor was his gentle, supportive yet challengingteaching style. Peter had an extraordinaryability to inspire students with a drive tounravel the Earth's puzzles presented by thegeologic record in mountain systems. Alumniof the Geosciences Department who workedon the legendary "Coney Project " -students'independent and in -depth studies of a chosengeologic area -often say it was one of theirmost valuable educational experiences and adefinite asset in their professional careers,citing him as "a great educator and anextraordinary role model." Peter Coney waswithout question one of the best educators inthe geological sciences.

Peter is survived by his wife Darlene, theirson Michel and their daughter Marian.

To Peter Coney the teacherwho turned science into art and made an art out of science,who sought truth in every student,who taught his students to care for details without losing the mountain

behind the rocks,who gave us knowledge and broadened our understanding.

To the geologist, a cornerstone of his field, primus inter pares.To the pilgrim of the mountains

who revealed their architecture both in rigorous concept and serene aesthetics,

who, based on facts simple and tangible, made a creed of "if it happened,it is possible ".

To the philosopher and the scientist.To the keen and sharp mind; to the boundless spirit.To the kind and understanding person, humble and modest.To the artist, to Peter Coney.

-Elena Shoshitaisvili and Sergio Castro -Reino


Peter Coney: An AppreciationThese reminiscences are excerpted from amemory book put together by PhD candidateElena Shoshitaishvili to be presented to Peter'sfamily.

Deter was a paradox in some ways. Ascapable of soaring flights of fresh

intellectual imagination as any scientist in theworld, and just as quick as anyone alive toabandon worn out theories, he could also bestubborn as a mule once an idea had becomefirmly embedded in his unique brain. Thosetwo facets of his scientific style were but flipsides of the same coin. Blessed with an innateconfidence in his own judgment, Peter sawno sense in continued allegiance to conceptsthat failed his personal test of validity, nor anyreason to back off from his own ideas in theface of criticism. His brand of geoscience wasin some ways a solitary effort, yet he neverlacked for followers and his sphere ofintellectual influence was always a wideningcircle, like the ripples on a pond into which astone is cast. - William Dickinson

Sometimes Peter would let me dosomething knowing that it was wrong. I

guess he wanted me to learn from myexperience. The best example of it is the uglygreen maps of North America hanging on thewalls of Peter's lab. The last time I saw Peter,we were talking about something, and helooked at the maps, so I asked, "Peter, whydid you let me color them into such uglycolors ?" He laughed and said, "To color mapsthe way that they talk to you, Elena, is an art."

-Elena Shoshitaishvili

Peter would often describe a personas "civilized." It was a simple term that he

used, but one he chose carefully; itencapsulated a person's character and aquality encompassing the highest standards

(photo by George Davis)

of humanity. Our conversations always had astrong impact on me and always left mefeeling more "civilized," for Peter had a wayof moving the people with whom he spoke.Most of all, Peter was a civilized man, anindividual who embodied the very best inhuman qualities and civility. His being hasenriched us all. -Roy Johnson

In order to understand Peter you have toknow that he was brought up as a traditional

Quaker. Quakers are taught to only speak, ina meeting for example, when they feel moved.They are supposed to be succinct and notrepeat themselves. So this one trip I took downto Hermosillo with Peter, I made up my mind:.I wasn't going to speak until he spoke. Wewere halfway down to Hermosillo before hesaid anything! -Paul Damon

Itwas in teaching that Peter's real nature and

calling lay. Many students who passedthrough the University of Arizona, andexperienced Peter's courses on Orogenic Belts,will never forget the inspirational experiencethat they enjoyed. All of his colleagues hearthis memory regularly, even from geologistswho were students here ten or twenty yearsago. Peter rejoiced (no other word applies) inthe inspired transmission of understanding,whether from himself to a class, to anindividual, or from others to himself. He wasdoubly appreciative of students who tookwhat he gave them and moved beyond it tonew thoughts and ideas. He rejoiced equallywhen students or colleagues conveyed newunderstanding to him. As in the researchdomain, his praise and gratitude to someonefrom whom he felt he had learned something,or to a student who had developedexceptional insight, was very uplifting.

eter's papers were imaginative andthought provoking. Of course, the papers

reflected the man -imagination, intuition,genius. -Joaquin Ruiz

North American Continental SurfaceDominated by Caledonian -Appalachian

Detritus for 300 Million YearsJonathan Patchett

A team of the Department's researchershave discovered that sediments from theCaledonian -Appalachian mountain systemwere deposited over the entire NorthAmerican continent 450 million years ago, anddominated the sedimentary system until 150million years ago. The dominance of thissediment was only terminated when a newmountain system, the western Cordillera,appeared and in turn became the majorsource. The findings were presented in Scienceon 29 January 1999. It is the first timegeologists have documented withgeochemistry the origins of sediment at thescale of a whole continent. The group ofresearchers include Jonathan Patchett,supported by former graduate students JamesGleason (PhD '94), Nevine Boghossian (MS'94) and Carmala Garzione (MS '96), formerundergraduates Michelle Roth (BS '97) andBret Canale (BS '96), and with the activecollaboration of faculty Bill Dickinson, GeorgeGehrels and Joaquin Ruiz. Gerry Ross of theGeological Survey of Canada is also a keymember of the group.

The river -borne sediments deposited overNorth America for 300 million years camefrom the Caledonian Mountains that formedin Greenland and the Appalachian Mountains

that formed inthe easternUnited Statesd u r i n gOrdovician time450 millionyears ago.

origin of shales created by the compaction ofthe sediments over time. They studiedsedimentary rocks from all parts of NorthAmerica, from Texas to far northern Canada.They found shale formed from sediment thatwas eroded from the same mountains acrossNorth America from 450 million years agoright up to the Jurassic period of the Mesozoicera, 150 million years ago

Before the Caledonian -Appalachianmountains existed, as far back as 600 million

years ago, at the end of the Precambrian era,sedimentary deposits around North Americawere regional deposits. Sedimentary rocks inthe Canadian Arctic and also Alberta clearlyhad been eroded from the ancient rocks ofthe Canadian shield. These rocks date frombetween 3 billion to 2.5 billion years old, andfrom between 2.0 billion to 1.7 billion yearsold. By contrast, sedimentary rocks in theeastern and southern United States formed

N. American ContinentalSurface cont'dfrom the younger continental crust presentunder most of the Great Plains. The pre -450million years picture is regionalized, accordingto the findings. The sedimentary material waseroded from rocks in the hinterland, much asthe Mississippi River carries material downfrom the Mississippi Basin today. But,suddenly, at 450 million years, everythingchanges. All the sedimentary rock has thesame Nd isotopic signature, and it appears to

come from the distant Paleozoic mountains. Thismaterial was reworked, perhaps over and overagain in some regions, for 300 million years.

At 150 million years ago, there is anotherrapid change, well known from Cordilleranstudies of many groups. The Cordillera beginsto grow across western North America, andnew and different kinds of sedimentarydetritus spread across parts of the continent.However, the Cordillera has not yet achievedthe same dominance as a sediment source,as was the case for the Caledonian -Appalachian mountains.

The paleogeographic and evolutionaryaspect of this story is that when mountainsare made, they can yield overwhelmingquantities of sedimentary material thatdominate the surface of that continent untilthe next mountains appear. Big changes inthe ultimate provenance of sediments areassociated with mountain building events, anaxiom that graduates of this department whoenjoyed the teachings of Bill Dickinson andPeter Coney should find quite credible!.

Center forEarth Surface

Processes

EstablishedOwen Davis

On March 4 -6, 17 scientists from the UAmet with 35 of their colleagues from the USGSto discuss collaborative research and a joint"Center for Earth Surface Processes" (CESP)at the UA. The lead programs for CESPresearch are to be the Dept. of Geosciencesand the Geologic Divison of the USGS.However, the Laboratory of Tree RingResearch, the Dept. of Hydrology and theInstitute for the Study of Planet Earth (ISPE)are to be important partners. The meetingbegan with 25 talks on climate change,ecosystem and landscape impact, waterresources and hazards, and environmentaleffects of resource exploitation. This wasfollowed by a USGS Managers meeting, a tourof Geosciences laboratory facilities, and adinner at the Desert Laboratory on TumamocHill. The next day (Saturday) introduced USGSscientists to Southern Arizona with a field tripto the upper drainage of the San Pedro River.Details of the meeting are available at http: //geo. arizona .edu /Antevs /surficial.html andhttp : / /climchange.cr.usgs.gov /cesp/

The creation of CESP continues a long-standing relationship between the USGS andthe department, which includes many of ourfaculty who are former USGS scientists, andthe many Geosciences alumni who nowoccupy positions throughout the USGS. Thisrelationship became an active collaborationin 1989 when geologists from the MineralsDivision moved into the fourth floor of theGould- Simpson building. The collaborativeresearch that resulted from our close proximityresulted in a host of research publications,theses, and dissertations. The spirit of

San Pedro River field trip participants Owen Davis, Todd Hinkley, Dave Kirtland, DaveMiller, Brenda Houser, Bob Kamilli, Don Gautier, Rick Forester.

collaboration is embodied in the MineralResources Center which currently includes fourGeosciences faculty, two USGS scientists, and18 graduate students (http: //www.geo.arizona.edu /cmr /) .

CESP will focus largely on climate change,surficial geological processes, land use, andother geologic phenomena that affect thelandscape, ecosystems, and human use of theland. Both the department and the USGS willbenefit from the intellectual interactions,opportunities for scientific collaboration,shared resources, and scientific focus that CESPwill provide. The enhanced ties to the UA willbenefit the USGS by providing scientific andstaffing flexibility, access to students, and tiesto local and regional constituencies. The UAwill profit by participating in the long -termscientific stability and planning provided byties to the USGS and by enhanced fundingand scientific opportunities for students.

Initially the CESP scientists will consist ofgeoscientists currently at the UA. However,within two years it is planned that USGSscientists will be hired to fill CESP positions,and senior USGS scientists may also join theCenter. Bob Thompson, Team Chief Scientist,Global Change and Climate History, Denver,and Owen Davis, Geosciences, are the actingco- directors of CESP.

The Society of Earth Science Students(SESS) had one of their best spring break fieldtrips ever this March to Northern Sonora,Mexico. Special guests included a KUAT PublicTV crew who filmed the trip for a segment ofThe Desert Speaks to be aired next year; FloydGray and Bob Miller from the USGS; YarPetryszyn, a UA ecologist; Fernando VasqueLopez, a geology student from the Univ. ofSonora; and Jose Luis Rodriguez, a geologistfrom the Universidad Nacional Autonoma deMexico. In all, we had a wonderful group of22 students, faculty and guests.

The six -day trip explored therich natural and cultural history ofNorthern Sonora. Some of thegeologic highlights included visitsto the 1887 earthquake fault scarp,Arizpe and other communitieswhich were impacted by the quake(estimated to be a magnitude 7plus); the hot springs at Aconchi,where students sampled springwater for a geochemical study andenjoyed its therapeutic value after afew days of dusty travel; Moctezumeto explore lava tubes in Quaternarybasalt flows on which grows the

Undergraduate students Arturo Baez andSean Haggerty were the principle organizersof the trip. Both are involved in anindependent study project involving thegeochemistry of hot and warm water springsassociated fault systems. Floyd Gray, who isinvolved in an international field study of thisregion, has invited Arturo and Sean tocontribute to a USGS open file report aboutthe region.

Although the geology and other naturalhistory explored on this trip was especially diverseand interesting, the biggest highlight for me wasthe great group of students and colleagues whoparticipated. Arturo and Sean did a superb jobwith trip organization; Alisa Miller, Mandi Lyonsand Michelle Wagner had plenty of SESS T- shirtson hand for our hosts; Dan Quinlan and Sergiohelped Arturo and Floyd with English /Spanishtranslation; the CB radios flared with almostcontinuous conversations about roadsidegeology thanks to Bob Casavant, Jan Lacanetteand others. And then there was the party on ourlast night in Nacozari where we were the guestsof the Honorable Gerardo Baez, the Mayor ofNacozari, and other city officials. The food, themusic, and the hospitality were fantastic -aperfect end to a fabulous field trip.


Active Tectonics Goes to "the Valleys"George Davis

Sue Beck and George Davis co- taughtActive Tectonics during the Spring '98semester, and one of the high points was theirfield trip to "the Valleys ": Death, Fish Lake,Owens, and Long (March 20 -26). Clem Chasecame too, contributing insights all along theway. Karl Mueller, active tectonist from Univ.of Colorado, brought six students fromBoulder to the Valleys.

The purpose of the trip was to betterunderstand the nature of the easterly part ofthe broad plate boundary between the NorthAmerican and Pacific Plates. Thus we felt itimportant to examine active tectonicexpressions along the Eastern California ShearZone and Death Valley. Two years ago Beckand Davis took their students to the westernpart of the same plate boundary, as expressedin downtown Los Angeles.

The trip was about FAULT SCARPS, onesin every flavor imaginable. Karl Mueller taughtus the ABCs of dealing with the neotectonic

and geomorphic expressions of scarp systems.Some of the scarps we examined were 80m tall,inclined at steep angles of repose, and composedusually of alluvial fanglomerates. Typically thesescarps were found to be somewhat eroded alongtheir tops, creating a little crestal rounding, andin- filled a bit at their bases by colluvial wedges.The most fun for us was, in each case, trying toevaluate the actual direction of fault slip andfiguring out the "partitioning" of strike -slip anddip -slip movement. Markers to assess thisincluded offset ridge crests, offset lateralmoraines, offset ancient shorelines, and the like.

While in the Death Valley pull -apart basinwe checked out the classic turtlebacks, andlooked at strike -slip scarps along the FurnaceCreek fault zone. Northward from Death Valleywe examined the most spectacular fault scarpsin the coterminus U.S., exposed on thewestern side of Fish Lake Valley.

Further northward we visited Walker Lake,yet another pull -apart feature, a classic

rhombochasm created at a releasing bend ina strike -slip system. Walker Lake, as a result, isDEEP, and is used as a U.S. Navy site for testingout submersibles and submarines. Creepyplace. Old bathtub rings around the lake serveas markers for fault displacements.

Somehow staying clear of late- winterstorms, we circled around to Mono Lakes andLong Valley, where we thought hard aboutthe Long Valley Caldera, the eruption of theBishop Tuff, the resurgence(s), and present -day seismicity. Then we drove to Bishop andup onto the Volcanic Tablelands, which forstructural geologists is a kind of mecca. Clearlyexpressed in the landscape are normal faultscarps that cut the top of the Bishop Tuff. Thefaulting is active, the scarps are fresh, and thereare dozens and dozens of faults. Because ofthis, it is possible to clearly see the transferzones between overstepping and overlappingfaults. We all ran out of film on the Tablelands!

Our final stops were along the OwensValley fault, where we examined theimpressive scarps that formed during the 1872earthquake. This was a biq quake whichcreated many meters of both strike -slip anddip -slip motion, with the ratio beingapproximately 6:1. Parts of the scarp werecompletely un- eroded, giving us a glimpse ofwhat a fresh scarp looks like in fanglomerate.

We all look back on an experience thatliterally opened our eyes to active tectoniclandscapes, and to the broad and diffuse natureof an important plate boundary. We concludedthat the plate boundary movement isaccommodated elegantly through thecombination of both strike -slip and normalmovements, as well as some occasional volcanicblasts.

ALUMNI NEWSIn Memory of

JERRY HARBOUR (PHD '77), who retired in1990 as an administrative law judge with thelicensing board of the Nuclear RegulatoryCommission, died on Sept. 14, 1988 in FallsChurch, VA.

Jerry worked in the military geology andastrogeology branches of the USGS early inhis career. He was a researcher for the Institutefor Defense Analysis before joining the AtomicEnergy Commission in 1972 where he was chiefof the site safety research branch at the NRC. Hebecame a technical law judge in the early 1980s.

A native of Coleman, TX, Jerry attendedthe Merchant Marine Academy and served inthe Air Force in Germany in the early 1 950s.He received BS and MS degrees in geologyfrom the Univ. of New Mexico and hisdoctorate from the UA in 1977.

Survivors include his wife of 47 years,Carol, three children and one grandchild.Carol writes that they and their children weredenizens of Polo Village while Jerry did hiscoursework and research for his PhD and thatthey have many fond memories of Arizona.

ALUMNI PROFILEDIANA HALLMAN (BS '97)

Diana Hallman has just been accepted to theUniv. of Florida where she will be working on herdoctoral studies in Zoology starting in Fall 1999.She has been awarded the Lucy DickinsonFellowship in Vertebrate Paleontology and a four -year Fellowship.

My name is Diana Hallman and I am inthe final year of study for my MS at NorthernArizona Univ. in the Quaternary StudiesProgram. I graduated from the UA with a BSin Geosciences in Fall 1 997. I am a Tucson nativeand of Mexican heritage. I am the first one inmy extended family to receive a degree from afour -year university and also the first one in myfamily to pursue graduate education.

While studying at the UA, I worked ontaphonomic studies of marine invertebratesunder the guidance of Dr. Karl W. Flessa. I feltvery fortunate to be able to conduct researchas an undergraduate. This experience wasinvaluable to me. It prepared me for mygraduate studies and greatly enhanced myapplication to my graduate program. It alsoplayed an integral role in the success of myapplication in the 1997 NSF MinorityFellowship competition.

Currently, I am working on my thesis withDr. Larry D. Agenbroad (NAU) and Dr. DanielC. Fisher (Univ. of Michigan). This researchfocuses on oxygen isotopic analyses ofbiogenic phosphate from southwesternproboscideans. I will use this analysis inconjunction with growth line studies ofmammoth tusk material to infer climaticseasonality, season of death, and life historyof the last few years of each animal's life. I

have also returned to the UA (they can't seemto get rid of me) to conduct the oxygenisotope analyses in Dr. Jay Quade's lab. Tusksand cheek teeth of proboscideans record thelife history of the animal including age, sex,age at sexual maturity, calving, and season ofdeath. These parameters provide informationof the ecological stress, nutritional andpredation patterns. By comparing thesouthwestern mammoth material withMichigan mastodon material and SouthDakota mammoth material, I will be able tolook at life histories and climatic signaturesacross the continent. In addition to providingdetailed environmental and life historyinformation, this research will aid inpaleoenvironmental interpretations and allowfor testing assumptions implicit in extinctionhypotheses.

Throughout my undergraduate career, Iwas supported by the AGI through theirMinority Scholarship Program. This supportwas essential as I pursued my undergraduatedegree. I am grateful for this assistance andam now pleased to serve AGI as a member ofthe Steering Committee to increaseprofessionalism in the 21st century. Thecommittee is putting together a conferencethat will be offered for undergraduate minoritygeoscientists and is proposed for Spring 1999.

In my doctoral work I would like tocontinue my research in oxygen isotopes asthey are quite useful in reconstructingpaleoenvironments. In addition, I would liketo look deeper in time at earlier Mioceneproboscideans and the role they played in theGreat American Faunal Interchange. Aftercompletion of my doctoral program, I wouldlike to obtain a position in academia that willallow me to continue my research inproboscidean paleobiology. As a facultymember, I look forward to the opportunity torecruit and mentor the next generation ofscientists. I hope to serve as a good role modelfor women and minorities in the sciences.(dianahallman @yahoo.com)


ALUMNI NEWSMARK ZOBACK RECEIVES ALUMNIACHIEVEMENT AWARD

Mark Zoback (BS '69)

The 1999 Department of GeosciencesAlumni Achievement Award was presented toDr. Mark Zoback during the 47th AnnualGeoDaze Symposium. The award is given inrecognition of outstanding accomplishmentsby a graduate of the department. Markreceived a BS in geophysics from the UA in1969, and went on to earn a MS and PhD in

Geophysics at Stanford. Mark then began acareer as a geophysicist at the USGS, wherehe was Chief of the In -Situ Stress MeasurementProject, Deputy Chief of the Office ofEarthquake Studies, and finally Chief of theBranch of Tectonophysics. In 1984 Mark wentback to Stanford as a professor of Geophysics,and is recognized as one of the world's leadingexperts on the state of stress in the Earth's crustand the physics of deep boreholes.

Mark moved to Tucson when he was 10years old, and naturally decided to attend thehometown university. Visions of geophysics,however, did not fill his head. Mark wantedto be a lawyer -his last name saved him fromthat fate. In the 60s class registration was donealphabetically, and by the time "Zoback" wasup for registration most of the classes Markwanted were filled. Hearing that Introductionto Geology was easy, he decided he ought toat least get rid of his science requirement. Theinstructor, Ed McCullough, proved such anexcellent teacher that Mark fell in love withearth sciences and any thoughts of torts andlitigation gave way to mountains andearthquakes. Mark began to look around fora specialty. He disliked excessive memorization,so thought he would look into geophysics and

made an appointment with John Sumner. Heknocked on John's door and said somethingto the effect, "I have a couple of questionsabout geophysics." John grabbed Mark's handand said, "Welcome aboard!" Afraid to leave,Mark became a geophysicist! Actually, onceMark started to work on geophysics problemshe knew the had found his calling.

Mark's professional work has focused onforces in the crust. He teamed up with his wife,Mary Lou Zoback, to demonstrate that stressindicators like earthquakes and bore holebreakouts can be used to develop consistentregional scale stress fields which reflect largescale tectonic processes. Mark has been a leadinvestigator on a number of deep continentaldrilling programs. The most widely known ofthese is the deep hole along the San AndreasFault in southern California. Mark's work haslead to the realization that plate boundariesare truly unusual places -they areextraordinarily weak zones embedded inotherwise strong crust.

In addition to being a distinguishedalumni of the Department of Geosciences,Mark has been elected a Fellow of theAmerican Geophysical Union and a Fellow ofthe European Union of Geosciences. He is alsothe recipient of the Kenneth CuthbertsonAward for Outstanding Service to StanfordUniv. This is Stanford's highest award to facultyand staff. Mark received this award for leadinga two -year effort to reiise the student judicialsystem at Stanford. -Terry Wallace

Terry Wallace Presented Outstanding FacultyAward by Geosciences Advisory Board

The Geosciences Advisory Board awardedTerry Wallace its Outstanding Faculty Awardat this year's GeoDaze Symposium. Terry wasrecognized by the Board for his excellence inseismological research, his contributions to theGeophysics program in the department, andhis record of service on both a local and anational level.

Terry and his students have made majorcontributions in understanding the occurrenceof deep earthquakes in subduction zones.Terry has also been on the forefront of seismictreaty verification with his work on nuclearexplosions. With the signing of theComprehensive Test Ban Treaty comes arenewed importance to seismic verification.Terry has been highly visible in WashingtonD.C. recently due to his work on the Indiaand Pakistan nuclear explosions last year.

Terry is an active leader in theIncorporated Research Institutions ofSeismology (IRIS), a nation -wide seismology

consortium and over the last decade he hasserved on four major IRIS committees,including the chair of the executivecommittee. Terry is also the newly -electedPresident of the Seismological Society ofAmerica.

GEODAZE'99.This year's GeoDaze Symposium

gathered students, faculty, alumni, industryfolk and friends together on April 8 -9 for the27th consecutive year of undergraduate andgraduate presentations in the earth sciences.Drawing an audience from as far away asAlaska, two poster and three oral sessions keptthe extended family of the Department ofGeosciences abreast of student earth scienceresearch being conducted at the UA.

Whereas the general success of GeoDazeis dependent on a number of individuals andinstitutions, the outstanding quality of studentpresentations truly separates GeoDaze fromits counterpart symposia. The EvaluationsCommittee, headed by Joy Gillick, pointed outthat the calibre of student researchpresentations underscored the wholesalesuccess of UA geoscience students in a diversearray of disciplines. The EvaluationsCommittee made significant strides towardsimproving the feedback and evaluationprocess this year. By making evaluation formsavailable to all, organizers worked towardskeeping the collaborative and cooperativenature of the department at the heart ofGeoDaze.

As in previous GeoDaze Symposia, anumber of groups recognized colleagues whohave made influential contributions to thedepartmental community and our fields ingeneral. With somber and admiringintentions, we dedicated this year's GeoDazeto Peter Coney. It is our belief that thecooperative nature of GeoDaze is and will

remain a legacy of the influence Peter had onthis department's students and our science ingeneral.

Mark Zoback of Stanford received thedepartment's Distinguished Alumni Awardand delivered the GeoDaze '99 keynote talkentitled "Crustal Faulting and Fluid Flow -Some New Ideas about an Old Problem." Wesalute Dr. Zoback and recognize hiscontributions to our science.

Terry Wallace was presented with the1999 Outstanding Faculty Award by thechairman of the Alumni Advisory Board, SteveMay, for his recent professional and teachingachievements in global seismology. Steve alsoupdated the department on the progress of

the Advisory Board at its annual GeoDazemeeting.

John Lindquist of E.L. Montgomery andAssociates presented that company's generous$1000 Best of Show Award to Steve Ahlgren.

Finally, as we recover from the organizedchaos that is GeoDaze, we would like to thankand recognize all of the contributors toGeoDaze '99. With the help of studentcommittees, financial benefactors, alumniassociates, faculty members and staff support,GeoDaze promises to continue to be a sourceof pride for all facets of the Department ofGeosciences at the UA.

JohnAnthony'sAutobiographyPublished

John Anthony (BS '46, MS '51), UAGeosciences professor from 1951 to 1986,hammered out his autobiography as a larkduring his retirement. Following John's deathin 1992, his son Ryan edited the text,compiling old photographs, artwork, andeven song lyrics. He and John's wife Elizabethhave privately published 300 copies fordistribution.

During his 35 years at the UA, JohnAnthony played a significant role in theevolution of a small, mining- focused geologydepartment into a large, diversifiedgeosciences program. John's scientificcontributions included Mineralogy of Arizona(1977), senior authorship of the Handbook ofMineralogy (vol. 1, 1990), and a series ofpapers describing new mineral species andtheir crystal structures. He was also thefounding editor of the Arizona GeologicalSociety Digest. John moved to Tucson to enrollat the UA in 1944 to finish a degreeinterrupted by World War II. Upon thecompletion of his BS, he worked for theArizona Bureau of Mines. John earned his MSin 1951 and joined the faculty at the UA,where he assumed responsibility for teachingintroductory mineralogy and ore microscopycourses formerly taught by his own advisor,Max Short.

John's teaching responsibilites expandedto include topographic surveying and fieldmapping during the era before Field Campwas established. In 1965, John completed hisPhD from Harvard. The remainder of histeaching career at the UA centered on coursesin mineralogy and crystal structuredetermination, with occasional stints as FieldCamp director and instructor.

John's service to the department alsoincluded two years as its chairman. Hisstewardship of the UA Mineral Museum formore than a quarter of a century helpedpreserve and expand one of the best universitymineral collections during a time whensupport for museums was almost nonexistent.

From MyEarly Days

by

John Williams AnthonyWherein is recalled

a little of what it was like growing up in New Englandand the West a generation ago, lightly leavened by

charismatic characterizations of a panoply of pertinentprogenitors, relevent relatives, fortuitous forebears,

consanguineous collaterals and antiquated antecedents,abetted by assorted additional atrophied ancestors.

John Anthony at the UA Field Camp near Young,Ariz., May or June 1972.

Getting off the train in Tucson, Ariz. wassomewhat less pleasant than gettingon in Boston. The Southern Pacific

pulled into the Old Pueblo around 6:00 p.m.on July 9 (I think it was), 1944, a day that Ilater learned had hit 106 degrees -locally, onemight say that the ice had finally broken upin the Santa Cruz River. I should have beenready for it, because there had been no air -conditioning on the train, pulled in those daysby a steam locomotive, and the trip fromTucumcari, NM (where they took off or puton the liquor car, I can't ever rememberwhich) was sweltering. But that penultimatestep out the Pullman door onto the metalladder above the glaring white cementplatform took me directly into the fireball ofthe last afternoon sun. For a moment Isublimininally debated an about -face andcontinuing on to a more suitably civilizedCalifornia climate. One should have beeninured to Arizona's climactic surprises, but my

earlier Western sojourns had been eitherfarther north and in the mountains of MohaveCounty or in milder Bay Area California, andboth at a forgettingly -early age. As one whocarefully plans ahead, I foresightedly had onmy three -piece shaggy wool suit, a linedraincoat /overcoat over my arm, and a brownfelt fedora on my head, and I was weighteddown with two heavy leather suitcasescontaining my worldly goods- except for iceskates and skis. And, fresh from a couple ofmonths of in- hospital conditioning, I probablyweighed in at around 135 pounds. Thoughtsof frying pan and fire flashed briefly. Nowelcoming mat was out, so I struggled acrossa,couple of streets to a small hotel, whereexperienced my first evaporative cooler -cooled night. That hotel (whose name I nowforget) is still there, merely smaller and dingier.

There is only one University of Arizona inArizona, and it is situated in Tucson, at thattime a community of less than 35,000 sun -kissed souls, so the next day, armed withdirections, I set out under an underpass thenceeastward on East Sixth Street to find it. After alengthy walk in the morning heat (sans coatnow!), I came to a large, appropriate -lookingstructure, swarming with youth, which Ientered, eager to enroll. I discovered, to myembarrassment, that this was Tucson HighSchool- having an enormous enrollment inthose days, it being the only high school intown, save for the relatively smallAmphitheater -not the U of A! To this day, Ican't drive by THS without recalling that nearmiss. The story goes over well in Tucson.

Interpreting Pre- J uaternarvy

Climate from the Geologic Record

Interpreting Pre- Quaternary Climate fromthe Geologic Record is a compendium ofpaleoclimatic indicators from the pre -Quaternary geologic record, ranging from

foraminifera to reptiles, reefs to evaporites, andhow they are used to interpret paleoclimate.The approach is methodological, nothistorical, partly because historicalpaleoclimatology has been covered in otherbooks and long papers. My principalmotivation for writing the book was to providea way to systematically access the vastliterature on methods of studying pre -Quaternary paleoclimatology. As a

compendium, the book does not treat eachtopic in great depth. However, thebibliography is copious, so the reader caneasily gain access to more detail in theliterature by using the references provided asa starting point, Why the pre -Quaternary? TheQuaternary Period (roughly the last 2 millionyears) has been nicely addressed in book formby other workers. The methods used to studyclimates in the Quaternary and pre -Quaternary records overlap, but there are alsomajor differences. In addition, there are uniqueconsiderations for the study of pre -Quaternaryclimates, such as continental drift, higher sealevels, highly variable rates of volcanism, andvery different vegetation patterns, which allforced the climate system in ways that havenot been duplicated in the last 2 million years.

Harvard, Louis L. Jacobs (MS '73, PhD '77) ofSouthern Methodist Univ., and YukimitsuTomida (MS '78, PhD '85) of the NationalScience Museum in Tokyo are editors ofAdvances in Vertebrate Paleontology andGeochronology. This volume of collectedpapers, dedicated to Everett Lindsay, waspublished as No. 14 of National ScienceMuseum Monographs in Tokyo. In their"Appreciation of the Doc ", the editors and fellowalum Louis H. Taylor (MS '77, PhD '84) writethat Ev's retirement after 29 years with the UA"provides an opportunity for former students andcolleagues to reflect on the accomplishments oftheir mentor and friend. This book, in honor ofEv Lindsay, is such a reflection manifested inoriginal work, each contribution coherent in thewhole because it has some connection throughthe authors to the Doc."

Edwin Colbert (Curator Emeritus of theAmerican Museum of Natural History) notesthat Ev, "an outstanding authority onmammalian evolution, is rightly honored inthis collection of papers for his contributionsdevoted to descriptions and interpretations

His publicationsmay be categorized within two major themes:the descriptions of fossil mammals from theAmerican Southwest and Asia, and theapplication of magnetostratigraphy tovertebrate paleontology. Ev Lindsay may beconsidered as one of the pioneers in this last -mentioned field of study."
