"A summary of the first 100 years of published knowledge, including the chief occurrences of 445 mineral species."

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.

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 about the known facts about the minerals that make up the rocks, soils, and ore deposits of Colorado.

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.

From abstract: The Drum Mountains are in west-central Utah 30 miles northwest of Delta, between the Sevier Desert on the east and Whirlwind Valley on the west. It is a typically barren desert range comprising a westward-tilted structural unit in which is exposed as much as 9,000 feet of quartzite (Cambrian and Precambrian?) and 3,000 feet of carbonate rocks of Cambrian age. These beds, which strike northward and dip west, are cut by myriad east- to northeast trending faults with displacements of a few feet to a few thousand feet. Quartz monzonite dikes, pebble dikes, and vein deposits are present locally along the faults. The Cambrian rocks are overlain unconformably by volcanic rocks of probable Tertiary age.

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.

From introduction: The greatest known potential oil resource in the world occurs in the oil shale of the Green River formation, and the richest and thickest deposits occur within the area of this report. The purpose of this investigation was to obtain data on the stratigraphic distribution and areal extent of the oil-shale beds and to estimate the potential oil resources in the area.

From abstract: The area mapped is on the east coast of Prince of Wales Island, southeastern Alaska, about 35 miles northwest of the town of Ketchikan. Deposits of magnetite and copper in the mapped area and on Kasaan Peninsula, which adjoins it on the southeast, have been mined for copper and have produced more than 600,000 tons of ore valued at more than $6 million.

From abstract: Buried placer deposits in a belt about 8 miles long by 1 mile wide at Tofty, near Manley Hot Springs, Alaska, have yielded a few hundred tons of cassiterite as a byproduct to the recovery of several million dollars in placer gold.
