A report regarding a reconnaissance performed in the Darby mountains District, the Seward Peninsula, Alaska, performed in order to locate radio deposits.

Abstract: Reconnaissance for uranium in coal and black shale in New Mexico during 1952 was largely an extension of work initiated during the 1951 field season. No uranium deposits of economic interest were found, although minor amounts of uranium were noted at several localities.

From introduction: This report summarizes the basic information that has been collected on 49 wells and test holes in the Nevada Test Site, together with information on 9 springs.

The following report covers potentiometric studies with hydrogen-sensitive and cation-sensitive glass electrodes supplemented by chemical determinations and X-ray diffractions on a hydrogen-montmorillonite. These studies indicate that the clay behaves as a mixture of two acids, resulting from the presence of interlayer and edge exchange sites, both occupied by hydrogen ions.

A report about the optical properties of rutherfordine.

A report about spectrographic determination of lead in zircon and in some other minerals has been made by the U. S. Geological Survey to provide data in a study of the age of the rocks that contained these particular minerals. Overall, standard spectrographic procedures were applied, including the split-filter method for calibrating the photographic emulsion.

Report summarizing findings of investigations for radioactive source materials in Alaska from 1945 through 1954, and assessing possible Uranium sources in the state.

Report discussing the thorium and rare-earth deposits that are found in a six-mile long belt of pre-Cambrian carbonate rocks associated with potash-rich igneous rocks of probable pre-Cambrian age in the Mountain Pass district of San Bernardino County, California.

A report regarding thorium resources located in the Mountain Pass District in San Bernadino County, California

The following report provides findings of trace elements from investigations on Cache and upper Peters Creeks in the Tentana District, Alaska after discovering radioactive minerals within Geological Survey's collection of Alaskan placer deposits. This investigation took place in the summer of 1945.

The following report provides information that follows investigations of radioactivity in certain rocks found in Wyoming and South Dakota during the summer of 1945. Uranium is the principal element in this report with thorium as secondary.

Report discussing the progress made on various geologic studies during the period from April 1 to June 30, 1952.

From transmittal letter: This report contains the results of radiometric examinations of 39 mines and prospects, and a detailed description of the properties examined.

Report discussing a radiometric examination that took place in 1950 to determine the grade, reserves, and mode of occurrence of uranium and thorium in east-central Idaho and south-western Montana.

From abstract: Field work leading to this report was done by the U. S. Geological Survey for the Division of Raw Materials of the U. S. Atomic Energy Commission, Nearly 24 townships were mapped in the central part of the Great Divide Basin, Sweetwater County, Wyoming, Fourteen of these townships contain outcrops of uranium-bearing coal. Thirty coal beds were mapped, but only seven of them have uranium-bearing coal reserves as defined in this report.

Report discussing the U.S. Geological Survey's investigation for uraniferous coal in the central region of the Great Divide Basin of Sweetwater County, Wyoming.

Report summarizing the general geologic relations of some uranium deposits in the San Juan Basin, speculating on the origin and localization of some individual deposits and the entire SanJuan Basin mineral belt, and attempting to appraise the chances for discoveries of additional deposits.

Report discussing a method for the volumetric estimation of the oil yield of oil-bearing shale. The method can be applied to both shale and phosphatic shale.
