A salt-S-limestone deposit located 8.1 km (5.0 miles) SE of Moss Bluff (town) and 12 miles SSE of Liberty, on private land. The dome was discovered in 1926 and the sulfur was discovered in 1944. Operated by the Texas Gulf Sulfur Company. Produced during the period 1948 to 1982 but production was erratic during the period 1974 to 1982. MRDS database stated accuracy for this location is .
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 Middle Jurassic Louann Limestone and the Late Jurassic Louann Salt. The ore body has a depth-to-top of 274.32 meters. The depth to caprock is 591 feet, to the sulfur it is 900 feet, and to the salt it is 1,077 feet. The salt volume was calculated at 11.2 cubic miles to 10,000 feet of depth. Local alteration includes the biogenic alteration of anhydrock to limestone. Local rocks include rocks of the Beaumont Formation, areas predominantly sand.
Local geologic structures include a piercement salt dome.
Workings include the wells and surface infrastructure necessary for the Frasch production of sulfur.

0.0117 - 2.588 Ma
|Beaumont Formation, areas predominantly sand|
Age: Pleistocene (0.0117 - 2.588 Ma)
Stratigraphic Name: Beaumont Formation
Comments: (from Moore and Wermund, 1993a, 1993b) Yellowish- to brownish-gray, locally reddish orange, v. fine to fine quartz sand, silt, and minor fine gravel, intermixed and interbedded. Includes stream channel, point-bar, cravasse-splay, and natural levee ridge deposits, and clayey fill in abandoned channels. Forms poorly defined meander-belt ridges and pimple mounds aligned approx. normal to coast and 1-2 m higher than surround interdistributary silt and clay. Channel fill is dk-brn to brnish-dark-gray, laminated clay and silt, organic -rich. Includes marine delta-front sand, lagoonal clay, and near-shore marine sand beneath and landward of bays along the coast. Interfingers with the interdistributary facies of Beuamont Fm. and rests disconformably on Lissie Fm. Thickness 3-10 m on outcrop; thickens in southeastward in subsurface to more than 100 m.
