460:307—STRUCTURAL GEOLOGY COURSE INFORMATION Description: Investigation of how rocks deform on

various scales using field examples, results of scaled experimental modeling, and seismic-reflection profiles. Topics include: geometry and origin of brittle and ductile structures; strain, stress, and rheology; deformation mechanisms; introduction to tectonics and regional structural geology.

Classes M4 Tu4 W4 Th4 WL-231 Prerequisites 460:101, 103; Calculus (optional,

but highly recommended) Corequisite 460:341 (optional, but highly recommended—joint field trips) Instructors Roy Schlische & Martha Withjack Basis for Grade • Exercises, quizzes, lab & field reports, homework: ~75% • Open-book tests: ~25% • A: 90-100; B+: 84-90; B: 78-84; C+: 72-78; C: 66-72; D: 50-66; F: <50 Required text None. Reading assignments from various textbooks will be available in WL-253

(Faculty-Student Lounge). Assignments: Unless otherwise noted, all assignments are due at the start of the class period on

the date assigned. Late assignments are penalized as follows: before 4:30 pm of the same day, -5%; before 4:30 pm of next school day, -15%; before 4:30 pm of 2nd school day, -45%; after 4:30 pm of the 2nd school day, assignments will not be accepted. Assignments must be given to RWS, AH, or Jovani Reaves, the Geology Department secretary, who must write the date and time on the assignment.

For ALL assignments: (1) All pages must be stapled or bound with a paper clip. (2) Your name

must appear on each page. (3) If the assignment involves multiple exercises, the exercises must be properly numbered and submitted in the proper sequence. (4) For numerical or graphical problems, you must show all your work, the final answer should be boxed, and all numerical answers must be accompanied by the proper units (e.g., 35 meters, 26°, 45 MPa).

For ALL exercises requiring a written answer: All answers must be typed. You must use

complete sentences, and give the reason for your answer. Grammar, spelling, and writing style will be graded along with content.

Attendance: All students are expected to attend all class periods and field trips. All students are

expected to arrive on time (1:40 pm) and to remain in class until the end of the class period (3:00 pm), unless dismissed by the instructor.

Field Trips: Three field trips will take place in April. Attendance is mandatory. Two of the trips are

held jointly with the Stratigraphy class. Written reports and/or exercises related to the trips will be due following each trip. Students who miss a field trip will have to write a term paper as make-up.

E-mail: Please check your email regularly regarding any changes in the syllabus, due dates for

assignments, reminders about field trips, etc. If you have a non-Rutgers email that you prefer to use, please inform us of the email address.

Supplies: 3-ring binder* (for holding handouts, notes, assignments, etc.; it is imperative that you

keep this notebook organized), colored pencils with erasers*, protractor*, metric ruler*, calculator*, masonite board or sturdy cardboard ( ~8.5” x 11”, for mounting stereonet), tracing paper, drawing compass, scissors, field notebook. *Bring these supplies to each class.
