A paper about Split Rock formation of Miocene age in central Wyoming. It contains mostly consolidated quartz sandstone with lesser amounts of tuff, pumicite, limestone, and claystone.

A report which includes 200,000 square miles in the southern part of the Williston basin of North Dakota, South Dakota, and Montana. The Devonian rocks consist mostly of marine carbonate, evaporite, and shale beds.

A report which presents the geologic results of an exploration program in the Lost Creek area by the U.S. Geological Survey in 1951-52 on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report about 24 townships in Wyoming which were geographically mapped. Fourteen of them contain uranium-bearing coal. There are 30 coal beds in these locations and seven of them contain the uranium-bearing coal.

Report issued by the Bureau of Mines over heavy sandstone deposits in the Four-State area of the U.S. Details of the geology and an estimate of resources are presented. This report includes tables, maps, and illustrations.

From introduction: Geologic mapping of the Carlile quadrangle, which includes one of several uranium-producing areas in northeastern Wyoming, was undertaken to provide a detailed geologic map that could be used as an aid to further exploration for uranium deposits; to study in detail the known uranium deposits to determine whether or not there are any relations among structure, stratigraphy, lithology, and uranium deposits; and to outline, insofar as possible, areas favorable for more detailed exploration for uranium.

This report studies Devonian rocks in an approximately 200,000-square-mile area between Williston Basin, central Montana, and north-central Wyoming.

This report follows fieldwork intended to determine distribution of uranium in coal in the central part of the Great Divide Basin, Wyoming, that was done between the summers of 1951-53.

This report presents the geologic results of an exploration program in the Lost Creek schroeckingerite deposits in northern Sweetwater County, Wyoming.

Report issued by the U.S. Bureau of Mines discussing magnetite and ilmenite mining methods and practices. As stated in the introduction, "this report summarizes the exploration of the titaniferous iron deposits in the Iron Mountain area, Albany County, Wyo." (p. 1). This report includes maps, tables, illustrations, and photographs.
