From abstract: Metatorbernite and bassetite are present in altered carbonaceous and quartzose slate of probable upper Huronian age. The slate is part of a small inlier of Huronian rocks between the Gwinn iron district to the southeast and the Marquette iron district to the northwest, Marquette County, Mich. Samples taken from a shallow trench, which was dug in the area of highest radioactivity, contained as much as 0.68 percent uranium. A 4-foot channel sample of the slate contained 0.036 percent uranium.

From abstract: A reconnaissance radioactivity survey of the Anaconda Copper Mining Company open-pit copper mine at Yerington, Nevada, was made in October 1953 to investigate the reported occurrence on one of the mine dumps of rock containing 0.022 percent uranium.

Abstract: A reconnaissance for radioactive minerals in the Shinarump conglomerate of Triassic age exposed north of the San Juan River at Balanced Rock anticline was made in July 1953. The purpose of the reconnaissance was to search for any exposed uranium minerals and to determine the favorability of the Shinarump for accumulation of uranium-ore deposits. No uranium minerals or places of abnormally high radioactivity were observed. However, nine exposed channels at the base of the Shinarump conglomerate and other channels, probably present where the base of the Shinarump is concealed, indicate the Shinarump may be favorable for uranium-ore deposits.

From abstract: Uranium deposits and radioactivity anomalies have been found in the eastern half of the area underlain by the Browns Park formation in northwestern Colorado, south-central Wyoming, and northeastern Utah. The deposits are in eolian, lacustrine, and fluvial sandstones, tuffaceous sandstones, and limestones all of which were deposited on two converging pediments during Miocene time. At least one eastern and one western facies of lacustrine and fluvial sedimentary rocks are separated by a belt of eolian sandstones. The faces may be distinguished in the field and by petrographic and heavy-mineral studies in the laboratory.

A report about uranium analyses and uranium distribution in the United States.

Report discussing a study exploring regional uranium and other trace elements' relationship to provenance, specifically post-cretaceous origins.

A report of progress during the six-months period from December 1, 1954 to May 31, 1955 on investigations of radioactive materials in the United States and Alaska.

From abstract: "A method is described for the simultaneous radioassay of the uranium and thorium series and potassium in common rocks, or materials of comparable activity, in which the series are in secular equilibrium. The method is based on the measurement of the counting rate in three bands of the photon energy spectrum derived from the gamma-ray excitation of a scintillation crystal."

From Abstract: "This report presents the results of a detailed laboratory study of uranium in an 8-inch core of coal and coaly shale from the Luman No. 1 coal bed in the northern part of the Red Desert area, Sweetwater County, Wyoming."

From Introduction: "The following annotated bibliography consists of references to published literature and open-file reports dealing with uranium in coal and associated carbonaceous shales in the United States; the listings include nearly all the pertinent reports available as of June 1955 and also includes some reports in preparation."

The following report covers a diamond drilling project in December 1952 that was started in order to obtain geologic and mining information and samples of uranium-bearing Chattanooga shale in the Youngs Bend area, near Smithville, Tennessee. This report presents uranium content discovered within the mines.

A report regarding the geology of the Copper King Uranium Mine, in Larimer County, Colorado.

This report is based on work done by the US Geological Survey on behalf of the Division of Raw Materials of the US Atomic Energy Commission.
