Principal facts and density estimates for borehole gravity stations in boreholes RRL-3, -4, -5, -6B, -7, -8, and -9 at the Hanford Site, Benton County, Washington
Borehole gravity surveys were conducted in seven boreholes, located within a 10-mile/sup 2/ (25-km/sup 2/) area in the northwestern portion of the Hanford Site, Washington, in June and July 1982 using La Coste and Romberg slim-hole borehole gravity meter (BHGM) BH-6. The primary objective was to obtain accurate, average, in situ densities of the sediments that overlie the basalts in the area. These density values along with lithology data and other well-log information will be integrated into a three-dimensional density model to be used with a detailed surface gravity survey of the area to determine the location of the top of the basalt, which varies between about 600 and 800 ft (200 and 270 m) below the surface. This study is part of the US Department of Energy's assessment as to whether the basalt is suitable for the storage of radioactive wastes. This report contains the principal facts obtained during the surveys and estimates of in situ bulk densities from these data. Also included are reduced sections of the gamma-ray logs with the BHGM station locations indicated and summaries of the stratigraphic section for each borehole. 9 references, 15 figures, 16 tables.
