This report is a statement of progress during a six-months period and gives the principal unclassified information developed in that period about investigations of radioactive materials in the United States and Alaska, and to a minor extent in foreign countries.

From introduction: This report is a statement of progress during a six-month period and gives the principal unclassified information developed in that period for radioactive deposits in the United States.

Report discussing a study revolving around montroseite and paramontroseite. This report is divided into several sections: source of the data, determination of the crystal structure of paramontroseite, refinement of the montroseite and paramontroseite structures by the method of least squares, structural features of the two, solid state alteration of montroseite, and other examples of solid state alteration phenomena.

From abstract: Elk Ridge is in southeastern Utah in the central part of San Juan County. It forms a conspicuous ridge on the north end of the Monument upwarp. During the summer of 1953 field work was largely restricted to South Elk Ridge, that part of Elk Ridge which is south of The Notch. Permian and Triassic sedimentary rocks crop out in the area and Jurassic and Cretaceous rocks are exposed east of the area.

Report discussing a study on secondary radioactive iron minerals closely associated with uranium and thorium deposits in various western states. From abstract: "A study on these radioactive 'limonites' was therefore undertaken in an attempt to find out in what form the radioactive material is present in the limonite, how it was introduced, and whether a field study of leached ferruginous cappings over uranium and thorium deposits might yield information about the depth, distribution, size, and grade of underlying ore bodies."

Report discussing the U.S. Geological Survey's reconnaissance for uraniferous carbonaceous materials in three areas of southern Utah: Kaiparowits Plateau, Henry Mountains, and Kolob Terrace.

Report discussing the results of core drilling in the Mendenhall Area of Harding County, South Dakota. This drilling was aimed at collecting data regarding uranium-bearing lignite. The report provides information regarding drilling operations, stratigraphy of the area, structure, and lignite deposits.

A report regarding the results of core drilling for uranium-bearing lignite, Mendenhall area, Harding County, South Dakota. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing a study in which uranium-bearing lignite was mapped and sampled in the Bullion Butte, Sentinel Butte, HT Butte, and Chalky Buttes areas in southwestern North Dakota.

Discussing deposits uranium-bearing lignite examined in the Southwestern North Dakota

A report about eleven occurrences of uraniferous argillite in the Lockatong lithofacies and five occurrences of uraniferous sandstone in the stockton lithofacies which are both of triassic age.

Report discussing the zoning of Bitter Creek mine vanadium and uranium deposits. Information regarding field work/acknowledgments, general geology, features of the mine, zoning of the mine, zoning of other parts of the area, origin of the zones, and conclusions are included.
