A former V-U occurrence/mine located in sec. 1, T29S, R24E and sec. 33, T28S, R25E, SLM, 1.5 miles E of the crossroads in the town of La Sal, on Bureau of Land Management administered land (located claim). Owned by Union Carbide. Operated by the Atlas Minerals Corporation, Utah (1974). MRDS database accuracy for this location is not stated.

Mineralization is a replacement deposit hosted in rock of the Morrison Formation, Salt Wash Member (Late Jurassic sandstone). The ore body is tabular, strikes N70E and dips 02S at a thickness of 1.5 meters and a depth-to-top of 152 meters. The primary mode of origin was other. Primary ore control was lithology. Controls for ore emplacement included paleochannels. Local rocks include Cretaceous (1) sedimentary rocks in southeastern Utah.

Workings include underground openings with a depth of 137 meters.

ID: 2183455
Burro Canyon Formation

Age: Early Cretaceous (100.5 - 113 Ma)

Stratigraphic Name: Burro Canyon Formation

Description: Sandstone, conglomerate, and mudstone, locally containing nodules and thin beds of limestone and shale; sandstone and conglomerate are mostly yellowish brown or gray, weathered surfaces are darker; sandstones are mostly medium-grained, moderately to moderately well sorted, with subrounded to subangular grains of quartz, colored chert, and white feldspar, commonly firmly cemented by quartz cement; conglomerate consists of black, brown, red, and grayish-green subangular to rounded pebbles and cobbles averaging 12 to 13 millimeters (0.5 in) in diameter in a matrix of coarse to medium-grained sand; formation has medium to massive lenticular beds forming ledges and cliffs; locally in three parts: a basal light-gray to yellowishbrown medium- to coarse-grained cross-bedded sandstone containing pebble conglomerate lenses and sparse silicified logs, overlain by a sequence of lightgreen mudstone and siltstone, overlain by shale with thin beds of siliceous limestone, chert, and orthoquartzite; the lower contact is generally mapped at the base of the lowest persistent sandstone; 24 to 90 meters (80-300 ft) thick, averaging 38 meters (125 ft); Lower Cretaceous, Albian.
