Chemical analyses of coal and shale from the Wasatch Formation in core hole B-1, city of Buffalo, Johnson County, Wyoming

During 1975, a continuous core (B-1) was taken through the uppermost 132.9 m (430 ft) of soil and rock underlying Buffalo, Wyo. The NX (7.6-cm (3in.)) bore hole is located in the NE 1/4 of the NW 1/4 of sec. 35, T. 51 N., R. 82 W., Johnson County, Wyo. (See index map in fig. 1.) The first 5.3 m (17.4 ft) was sampled by Shelby tube, the remainder by wire-line coring apparatus using a split inner tube. Bentonite-based drilling mud was used to drill that part of the hole below 30 m (98 ft). The core was preserved in approximately 15-cm (5.8-in.) lengths in sealed glass jars (Farrow, 1976).
