Abstract

Nonmarine carbonaceous rocks, including shales, coal, and peat, were tested at about 3 localities in California, Idaho, Nevada, Oregon, Utah, and Washington. Rocks ranging in age from Carboniferous to Quaternary were examine, although the principal attention was given middle and late Tertiary lignites of the northern part of the Great Basin. Most carbonaceous rocks examined contained essentially no uranium, but lignitic shales in the Goose Creek district, Idaho, a thin carbonaceous shale near Hagerman, Idaho, and a small peat deposit in Davis County, Utah contained more than 0.003 percent uranium.

"Granite" exploration hole, Area 15, Nevada Test Site, Nye County, Nevada : interim report, Part C, physical properties

Physical properties measurements including porosity, density, permeability, magnetic susceptibility, and thermal conductivity were made on granite samples from the U-15A 'Granite' exploration borehole, Nevada Test Site, Nye County, Nevada. Porosity values range from 0.4 to 4.8 percent, and density values range from 2.56 to 2.69 g/cc (bulk density) and from 2.66 to 2.72 g/cc (grain density). Permeability of fresh rock from the borehole is probably less than 10 -13 millidarcies. Magnetic susceptibility measurements range from 0.36 to 3.48 x 10 -3 cgs units, and thermal conductivity values range from 5.6 to 8.1 cgs units.

Lithologic log and drilling information for the Marble exploration hole 3, U15 area, Nevada Test Site, Nye County, Nevada

The Marble exploration hole 3 is in the northern part of the Tippipah Spring NE 7-1/2 minute quadrangle at the north end of Yucca Valley (fig.1). The collar elevation of the hole is about 5,316 feet and has the approximate Nevada State coordinates of N. 903,093 and E. 674,870. The hole was drilled to determine the physical and chemical properties of the marble within a radius of 200 feet of a point 950 feet below the surface. The exploration hole is 978 feet deep and was drilled from June 12 to July 8, 1959, by Minerals Engineering Co. of Grand Junction, Colorado, using conventional NX coring equiipment and a Portadrill 2,500 drill rig. Water-base bentonitic mud was used as the drilling fluid in the upper part of the hole. Clear water was used after circulation became unrestorable below 200 feet. The hole was cased from surface to 20 feet. The drilling rate during coring ranged from 2.0 to 19.3 minutes per foot and averaged 4.6 minutes per foot (table 1). The core recovered was excellent in quality and quantity. The average core recovery is 92.7 percent (table 2).
