A S-salt-limestone deposit/mine located 20.3 km (12.6 miles) ESE of Needville and 8.0 km (5.0 miles) ENE of Damon (Brazoria County), in the extreme SE corner of the county, on private land. Discovered based on a geophysical anomaly. The first production occurred in 1954. Last production was 1969. Production years were 1954-1956 and 1966-1969. Operated by Freeport Phelan (1954). MRDS database accuracy for this location is not stated. H2S was found in water wells. The dome was discovered in 1924 by gravity. This was the first salt dome discovered by gravity methods.
Mineralization is a salt dome deposit (Mineral occurrence model information: Model code: 255; USGS model code: 35a.7 (35ag); Deposit model name: Salt-dome sulfur), hosted in the Louann limestone and salt. The ore body has a depth-to-top of 289.56 meters. The depth to caprock is 620 feet, to the salt it is 950 feet and to the S it is also 950 feet. Salt volume was calculated at 2 cubic miles to a depth of 10,000 feet. Local alteration includes the biogenic alteration of anhydrock to limestone. Local rocks include rocks of the Beaumont Formation, areas predominantly clay.
Local geologic structures include a piercement salt some.
Workings include the wells and surface infrastructure for the Frasch production of S.
Production data are found in: Halbouty, Michel T. (1979).
