Abstract
The Saline Facies of the Upper Part of the Green River Formation Near Duchesne, Utah
Abstract
Core drilling in the vicinity of Duchesne in the southwestern part of the Uinta Basin, Duchesne County, Utah, penetrated several beds of mixed halite and sodium carbonate salts as thick as 19 ft. The evaporite beds are in the lower part of a saliniferous sequence of marly lacustrine rocks in the upper part of the Eocene Green River Formation. These rocks crop out in Indian Canyon several miles southwest of Duchesne, where they reach a thickness of about 1,100 ft. The bedded sodium salts underlie an area of about 86 sq mi near Duchesne at depths ranging from 2,400 to 4,200 ft below the surface. Preliminary study of drill core revealed a remarkable assemblage of authigenic sodium minerals including eitelite, wegscheiderite, nahcolite, trona, and others. Although these deposits are much smaller than the Wyoming trona and Colorado nahcolite deposits of the Green River Formation, they may have some potential for solution mining.
