A salt-limestone-Gypsum-Anhydrite occurrence located 4.1 km (2.5 miles) SSE of Brushy Creek (hamlet), on private land. MRDS database stated accuracy for this location is .
Mineralization is a salt dome (mineral occurrence model information: Model code: 252; USGS model code: 35a.4 (35ad); Deposit model name: Salt domes: diapiric salt structures. The deposit also classifies as USGS moldel: Gypsum (35A.6) limestone), hosted in Late Jurassic limestone and the Louann salt. The ore body is a diapir at a thickness of 6,705.6 meters, a depth-to-top of 1,073.51 meters, a width of 2,510.51 meters and a length of 2,574.88 meters. The caprock is 81 to 187 feet thick on the dome's flanks and is absent from the dome's crest. The depth to caprock is 3,522 feet, to the salt it is 3,570 feet and to the Louann salt it is 22,000 feet, with a surface expression of 1.9 square miles. Local rocks include Queen City Sand. Related oil fields are the Purt and West Purt fields.
Local geologic structures include piercement faults.
Reserve-Resource data are found in: Halbouty, Michel T. (1979); American Association of Petroleum Geologists Bulletin: 67 (1983).
reserve resource information was estimated from the top of the salt to 10,560 feet of depth. Estimated above Ecret James Limestone (Glen Rose Subgroup).
