ABSTRACT

The UE17e drill hole, located at the northwest corner of Syncline Ridge, was cored from

3.05 m (10 ft) to a total depth of 914.4 m (3,000 ft) in unit J (Mississippian) of the Eleana(Devonian and Mississippian) to obtain samples for mineral, chemical, and physical-propertyanalyses. UE17e penetrated 73.5 m (241 ft) of the quartzite subunit and 840.9 m (2,759 ft) ofthe argillite subunit of unit J. Less than 0.4 percent quartzite is present in the argillitesubunit. Dips range from 120 to 180. Twenty-three faults were observed in the core or ongeophysical logs. Most of these faults affect only a few meters of the core and probablyhave displacements of a few meters. The majority of fractures are parallel to bedding planes.Fracture frequency ranges from 3.4 to 9.4 fractures per meter in the upper part of the coredinterval and 1.4 to 5.9 fractures per meter in the lower part of the cored interval. Thecore index indicates that the lower part of the hole is more competent than the upper part.Lower competency in the upper part of the hole may be caused by weathering and(or) near-surface stress relief. Physical, mechanical, and thermal property measurements indicate that

-r bedding and fracturing are the major factors in variation of properties between samples.

INTRODUCTION

The UE17e hole was drilled to provide a detailed lithologic description of the quartzite

and argillite subunits of unit J of the Eleana Formation and to provide samples formineralogical, chemical, and physical-property analyses.

The UE17e vertical exploratory drill hole is collared in Area 17 at the NTS (Nevada TestSite) at Nevada State coordinates N. 260,056.8, E.197,656.03m(N. 853,204.70, E. 648,477.8 ft)at a ground elevation of 1,503.9 m (4,934.2 ft) (fig. 1). The drill hole is locatedapproximately 53 km (33 mi) north of Mercury, Nev., in the west-central part of the YuccaFlat at the northwest tip of Syncline Ridge (fig. 1). Total depth of the hole was 914.4 m(3,000 ft) within unit J of the Eleana Formation.

HOLE CONSTRUCTION

UE17e was spudded on November 24, 1976, and completed on January 9, 1977. The BoylesBrothers CP501 rig drilled a 19.69-cm (7 3/4-in.) hole to 3.05 m (10 ft) and set a 15.24-cm-

(6-in.-) ID (inside diameter) casing. UE17e was cored with a 10-cm (3.999-in.) core barrelfrom 3.05 to 914.4 m (10 to 3,000 ft). Core size was 6.67 cm (2.625 in.) Bentonite mudwas used as the circulating medium during drilling. Heavy (barite) mud was used to controlthe zones of squeezing during the geophysical logging of UE17e.

Core recovery was 96.3 percent. To provide natural-state samples for analysis,approximately 0.3 m (1 ft) out of 3.05 m (10 ft) of core was wrapped in heavy-gauge aluminumfoil and dipped in beeswax immediately after recovery. This process has proved effective inpast experience and is considered standard procedure. Geophysical logs include caliper,resistivity, inductives, gamma-ray neutron, three-dimensional velocity, and temperature.After logging, 3.30-cm- (1.38-in.-) ID tubing was cemented to a depth of 912.0 m (2,992 ft)to provide a stable medium for accurate temperature measurements.

GEOLOGY

Stratigraphy

Argillite by definition refers to the size of original particles as deposited. Mostargillites contain large amounts of clay minerals. However, clay mineralogy is not requiredin an argillite; only clay-sized particles. Argillites in the Eleana Formation, unlike most

4 argillites, are predominantly quartz and often contain 95 percent or more quartz. In thisreport, argillite that is predominantly quartz is termed siliceous argillite. The termargillite by itself refers to argillite containing large amounts of clay minerals or othersheet-structure minerals such as chlorite.

The Eleana Formation of Devonian and Mississippian age contains 10 units from unit Aat the base to unit J at the top. Only the units G through J are present in the SynclineRidge area (fig. 2). Unit J of Mississippian age has been divided,in ascending order, intolower, argillite, and quartzite subunits for mapping purposes only. The lower subunit isprobably 305 m (1,000 ft) or more in thickness. The argillite subunit has a stratigraphicthickness of approximately 700 m (2,625 ft); the quartzite subunit, approximately 100 m328 ft). The quartzite subunit is so named because the interval contains a greater proportionof quartzite than the underlying argillite subunit; the name is not meant to imply thatquartzite is the predominant lithology.

The lower subunit of unit J consists of siliceous argillite and quartzite; while theargillite and quartzite subunits consist of argillite, quartzite, siltstone, and limestone.Argillite in the quartzite and argillite subunits of unit J has been broken down into high-quartz argillite (from 25 to 45 percent) and low-quartz argillite (less than 25 percent) byvisual observation and laboratory analysis. Except for the quartz content,the mineralogy ofthe high-quartz argillite and the low-quartz argillite is similar. The argillite containsillite, kaolinite, chlorite, and other sheet-structure minerals.

UE17e is a continuous core hole from 3.05 m (10 ft) to a total depth of 914.4 m(3,000 ft) in unit J and is collared approximately 50 m (164 ft) below the stratigraphic topof the Eleana Formation. UE17e penetrates 73.5 m (241 ft) of the quartzite subunit and840.9 m (2,759 ft) of the argillite subunit, all within the upper part of unit J (table 1).

The quartzite subunit penetrated by the UE17e drill hole contains argillite (63 percent),siltstone (20 percent), quartzite (15 percent), and-limestone (2 percent) interbedded in verythin to thick beds. The argillite has been divided into high-quartz argillite (74 percent)and low-quartz argillite (26 percent) by visual observation and laboratory analysis. Thehigh-quartz argillite is brittle and separates along bedding planes; it is considered to becompetent rock and usually has a CI (core index) of less than 50. The low-quartz argilliteexpands and cracks when dry; it is considered to be incompetent rock and usually has a CI ofgreater than 50. The quartzites and siltstones are composed of almost pure quartz. Some ofthe quartzite grades to quartzitic sandstone. The limestone beds are very thin and occurjust above the quartzite beds. Both the limestone and quartzite beds are highly fractured.The bottom of the weathered zone is at 18.3 m (60 ft), as indicated by the lack of iron oxidebelow this depth. Some of the fractures are filled with calcite with no visible quartzpresent. Turbidity-current depositional structures are prominent in the quartzite subunit.The argillite subunit of unit J is penetrated at 73.5 m (241 ft) in the drill hole.

UE17e is still in the argillite subunit of unit J at the total depth of 914.4 m (3,000 ft).The argillite subunit contains very thick bedded argillite (99.6 percent) with four minorquartzite beds (0.4 percent). Approximately 80 percent of the argillite is high-quartzargillite and 20 percent is low-quartz argillite. The argillite is calcareous in scatteredareas throughout the section. Small amounts of pyrite in the form of nodules and disseminatedcrystals are visible throughout the interval. Many of the fractures are filled with calciteand(or) quartz. Many of the quartz-filled fractures show gentle to highly contorted folds,some of which have been sheared later.

Structure

The UE17e drill hole is located on the northwest tip of Snycline Ridge within theSyncline Ridge structural block (fig. 1). During the Mesozoic Era, the Paleozoic sedimentaryrocks in the Syncline Ridge area, including the Eleana, were involved in regional compression-al deformation. This deformation caused intense folding, thrusting, reverse and lateralfaulting, intense fracturing, shearing, and low-grade metamorphism of the Paleozoic

sedimentary rocks. Evidence of this deformation is seen in UE17e as highly variable bedding-plane dips, fractures, shear planes, faults, and folded and sheared quartz-filled fractures.

Bedding planes are prominent within the quartzite subunit, ranging from 10° to 35° dip.The bedding planes in the argillite subunit range in dip from 120 to 80° and are obscure.Bedding planes can usually be seen only by wetting the core and appear as slight color changes,possible related to a small difference in grain size, organic matter, or mineralogy.

Within UE17e there are numerous fractures and shear planes, the majority of which areparallel to the bedding planes. Many of the shear planes show a high polish. The fracturesare more abundant above 152.7 m (501 ft),and their number decreases with depth, indicating

possible stress relief near the surface. The higher fracture frequency and the shearingseen in UE17e above 152.71 m (501 ft) may also be explained by the proximity to a suspectedbedding-plane thrust fault at the contact between the Tippipah Limestone and the EleanaFormation. Twenty-one faults are penetrated by the drill hole (table 2). The faults wereidentified by visual observation of the core and with the aid of the geophysical logs. Thedisplacement of the faults could not be determined because of the very thick bedding.

The quartz-filled fractures have undergone intense deformation and Dinch out. Many ofthe quartz-filled fractures have been compressed into gentle to hiqhly contorted folds. Manyof the thin fractures as well as the gently to highly contorted folds have been sheared,indicating more than one period of severe deformation.

ENGINEERING GEOLOGY

UE17e was cored to a total depth of 914.4 m (3,000 ft) with 96.3 percent core recovery.A CI was calculated for each cored interval to determine the rock competency. A fractureanalysis was done on the core from 3.05 to 914.4 m (10 to 3,000 ft).

Core Index

The CI is a measure of rock competency. It is a dimensionless number from 0 to 100;50 being the dividing point between competency (0-50) and incompetency (51-100). Incompe-tency in the rock is generally due to jointing, faulting, and low strength. The CI is cal-culated by the following formula:

Ci-core lost (m)+core brokeneinW) +1/10 number of fracturesX 100drilled interval (in)

Lost core is defined as core that was not recovered from the drilled interval. Broken coreis defined as a length of recovered core fragmented into pieces less than 10 cm (4 in.) inlength. Fractures are defined as the number of natural fractures in the core, excluding thefractures in the broken core intervals. All natural fractures will limit the size of intactcore pieces greater than 10 cm (4 in.) in length. The total number of fractures is dividedby 10, thereby relating the standard length of unfractured core to 10 cm (4 in.), the upperlimit of broken core (J. R. Ege and M. J. Cunningham, unpub. data, 1975).-

CI histograms of the total argillite subunit were compared with three depth intervalsin the argillite subunit and the quartzite subunit. The histogram (fig. 3) for the totalargillite subunit from 72.8 to 914.4 m (238.9 to 3,000 ft) shows 48.2 percent of the rockto be competent and 51.8 percent to be incompetent.

CI histograms (fig. 4) for three depth intervals, 72.8-304.6, 304.6-610.2, and 610.2-914.4 m (239-999.5, 999.5-2,002, and 2,002-3,000 ft) show that competent rock ranges from25 to 63 percent. The 69.8-m- (229-ft-) thick quartzite subunit from 3.05 to 72.8 m (10 to239 ft) contains 99.3 percent incompetent rock.

The greater amounts of incompetent rock in the quartzite subunit and in the first argillitesubunit interval may be caused by weathering and(or) stress relief near the surface. Athrust fault near the Tippipah-Eleana contact may also affect the competency in these upper

Fracture Analysis

The dip of the fractures per 10°-dip interval, whether "open" or "closed," and regard-less of the type of fracture filling, were recorded for 911.4 m (2,990 ft) of core in UE17e.The rosette diagrams (figs. 5-17) show 10'-dip intervals from 00 to 90°; the number offractures in each 100 interval is shown by the length of the ray in each interval. Thehorizontal bar across the top of each rosette diagram indicates the fracture frequency. Onlynatural fractures, as opposed to mechanical fractures due to drilling and(or) handling, weremeasured. Fractures were classified as "open" or "closed" on the basis of their appearancein the core box. "Open" fractures are those fracture surfaces which are exposed in the corebox.

In UE17e (table 3, figs. 5, 6), the average fracture frequency for the 914.4-m (3,000-ft)core is 4.3 fractures per meter. Above 152.7 m (501 ft) (fig. 5), the fracture frequencyis 8.4 fractures per meter. Below 152.7 m (501 ft) (figs. 5, 6), the fracture frequency is3.5 fractures per meter. The higher fracture frequency (8.4 fractures per meter) above 152.7 m(501 ft) is possibly due to the stress relief near the surface. The proximity to a suspectedbedding-plane thrust fault at the contact between the Tippipah Limestone and Eleana Formation,about 50 m (164 ft) stratigraphically above the collar of UE17e, may also be responsible forthe higher fracture frequency.

The fracture data from UE17e (figs. 5, 6) indicate that the majority of fractures a-eessentially parallel to bedding. The interval of bedding-plane fracture dips is large inUE17e because of the thick stratigraphic interval that has been deformed.

Separation of fractures into "open" and "closed" categories indicates that open fracturesare more numerous at nearly every depth (table 4; figs. 7-10). Open fractures were notcompletely healed and reopened during drilling and core handling.

The total number of fractures recorded for 911.4 m (2,990 ft) of core in UE17e is aboutfour times the number of bedding-plane fractures (tables 3, 4). Fractures without fillingsoutnumber those with fillings by an approximate ratio of 2 to I (tables 5-7).

The rosette diagrams of various fillings in open and closed fractures in UE17e (tables5-7; figs. 11-17) do not clearly suggest any significant effect on the rock competency. Foreach filled fracture there are two clean fractures. Fracture fillings can affect the coeffi-cient of friction along fractures. Fillings, such as quartz and calcite, may increase frictionalong the fracture; clay may reduce the friction. Clay-filled fractures outnumber quartz-and-calcite-filled fractures by a 2 to 1 ratio (tables 7, 8; figs. 13-17). The clay-filledfractures and the quartz and calcite-filled fractures decrease with depth while the morenumerous clean fractures increase with depth.

PHYSICAL PROPERTIES

Thermal conductivities at 250 Cwere measured by needle probe by the U.S. Geological

Survey, Menlo Park, Calif. Conductivities were measured about every 15.2 m (50 ft) both

axially and radially to natural-state core samples, the conductivities are listed in table

8. The conductivities differ radially and axially because of depositional features parallel

to bedding and because of mineralogy. The thermal-conductivity range for argillite in UE17e

was found to be 4.2 to 8.0 mcal/s.0 C. The accepted thermal conductivity range for shale is

3.3 to 7.3 mcal/s-OC.

Natural-state densities have been measured and the porosities have been calculated for

30 different core samples of argillite from UE17e (table 9). The average natural-state

density for the 30 core samples is 2.62 g/cm3. The calculated porosities average 8.8 percent.

Geomechanical measurements were conducted on 15 core samples from UE17e (table 10).
