A clay(bentonite)-gypsum occurrence/mine located in sec. 18, T15N, R7E, SBM, 13.8 km (8.6 miles) W of Silver Lake (locale), along the western margin of the Silurian Valley (E margin of the Avawatz Mountains). Discovered in 1900. MRDS database stated accuracy for this location is 250 meters.
Mineralization is hosted in tuff and Pliocene lake sediments. 13 meters of altered tuffaceous sediments are exposed in the main pit. Pale greenish-gray clay and gypsum beds crop out at an elevation of about 533 meters. The ore beds strike N70W and dip 50NE. To the S, the beds are folded, uplifted and truncated by a Late Cenozoic fault. The deposit is overlain by poorly-sorted fanglomerate. Local rocks include Tertiary nonmarine rocks, undivided.
Local geologic structures include Late Cenozoic faults.
Workings include surface openings. Prospect pits are scattered. The main clay pit is located between two playas - Fort Irwin and Silver Lake.
