"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.
