A salt deposit located 4.8 km (3.0 miles) ENE of Tyler center, on private land. MRDS database accuracy for this location is not stated.
Mineralization is a salt dome deposit (Mineral occurrence model information: Model code: 252; USGS model code: 35a.4 (35ad); Deposit model name: Salt domes: diapiric salt structures), hosted in the Late Jurassic limestone and the Louann Salt. The ore body is a diapir with a thickness of 6,400.8 meters, width of 4,666.97 meters, length of 5,310.69 meters and a depth-to-top of 243.84 meters. The caprock is 90 to 277 feet thick. The depth to caprock is 800 feet, and to the salt it is 890 feet, and to the Louann Salt is 21,000 feet. The surface expression is 7.4 square miles. Local rocks include the Sparta Sand. This deposit also classifies as USGS model Gypsum (35A.6) limestone.
Local geologic structures include piercement faults.
