From abstract: "The Crevasse Canyon formation and Point Lookout(?) sandstone of Late Cretaceous age and the Baca and Datil formations of Tertiary age were mapped in an area of 168 square miles in the upper Alamosa Creek Valley along the northern edge of the Datil Mountains, Catron County, N. Mex. The investigation was made to determine the potentialities of the area for producing uranium and to learn the geologic controls for the concentration of uranium."

Report discussing a spectrographic determination of contamination in rock samples that had been pulverized with heavy grinding machinery made of alumina ceramic.

Report presenting the results of one part of an investigation of the regional geology of central Florida.

Report discussing two botanical methods of prospecting for uranium ores on the Colorado Plateau. The first method involves analyzing tree branch tips for uranium content, and the second involves the mapping of indicator plants.

A report about the absorption spectra of the thallium-dithizone mixed-color system. An analytical procedure based on this system is given which is applicable to pure solutions.

Report discussing an investigation of intrusive igneous rocks for radioactivity in New Jersey, New York, and New England during August and September 1951. This was aimed at finding uranium contents of economic significance in these rocks and determining the geological cause for any radioactivity. Results of the investigation are given by region, and a summary is included.

From abstract: "A method is presented for the separation and spectrophotometric determination of thorium in zircon and other associated minerals... The steps necessary for the separation of interfering ions are discussed, and a study of the effect of various cations and anions is presented."

Report discussing the geology of the Rainy Day uranium mine in Garfield County, Utah. From Introduction: "This report describes the relation of the uranium deposit to the local geology and presents several ore and subore analyses which show similarities between this deposit and those in the Shinarump and Moss Back members of the Chinle formation of the Triassic age."

From abstract: The Rainy Day mine in the Circle Cliffs area, Utah, is developed Dn a long slender pod of uranium ore. Ore is localized in siltstone of the Moenkopi formation of Triassic age, on the south edge of a channel about 3,300 feet wide by 40 feet deep that is filled with sandstone of the Shinarump member of the Chinle formation of Triassic age. Shale of the Chinle rests directly on siltstone of the Moenkopi on either side of the channel.

Report discussing new cell dimensions, space groups, specific gravity determinations, and number of formula units per cell for uranyl vanadates, phosphates, and arsenates.

The following report describes a laboratory sample splitter, the slotted cone splitter, designed in in the form of 60[degree] cone.

A report about spectrophotometric determination of thorium with thoron. Also, mesotartaric acid was used as a masking reagent for zirconium.

Report discussing the stratigraphy of the Morrison Formation in northwestern New Mexico. From Introduction: "The field work on which this report is based was done during the summer of 1954 when the authors were engaged in investigating the uranium resources of northwestern New Mexico..."

From abstract: This report describes the Rainier underground test of September 19, 1957 conducted at the Nevada Test Site with a 1.7 kiloton nuclear device.

From abstract: Radium-bearing precipitates derived from 'oil-well fluids have been found in more than 60 oil and gas fields in Cowley, Butler, Marion, Sedgwick, and Greenwood Counties of southeastern Kansas. The abnormal radioactivity of these precipitates has been studied through the use of gamma-ray and sample logs; by radiometric, chemical petrographic, and spectrographic analyses of the precipitates and drill samples; and through the use of chemical analyses of brines collected from oil wells in the areas of high radioactivity.

Report discussing an experiment in which the abnormal radioactivity of radium-bearing precipitates derived from oil-well fluids taken from more than 60 oil and gas fields in Cowley, Butler, Marion, Sedgwick, and Greenwood Counties of southeastern Kansas were studied.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.

From Foreword: "This manual was written to serve as a guide for analysts interested in the determination of small amounts of uranium. All of the methods presented here have been developed in the U.S. Geological Survey and are based on the measurement of the fluorescence of uranium in fluoride melts."

From Introduction: "The purpose of this report is to present the preliminary results of the geologic reconnaissance and office work leading to an appraisal of the geologic relations of the uranium deposits of the San Rafael district, Emery County, Utah."

A report presenting the preliminary results of geologic reconnaissance and office work leading to an appraisal of the geologic relations of the uranium deposits of the San Rafael district, Emery County, Utah.

Report discussing spectrographic analyses of rocks, ores, mill products, and smelter products. From Abstract: "The analyses are grouped by states and by major raw mineral raw materials. The samples vary widely in character and in kind of material. They were analyzed chiefly by spectrographic methods, the accuracy of which increased during the later stages of the work."

From translator's abstract: "As part of unified research on the behavior of the fluoride ion in sedimentary rocks, the present study deals with the system CaO-P2O5-HF-H20 at 25 degrees C. under conditions of sea sedimentation. The precipitated phases, their fields of crystallization and stability, the fluorine-phosphorus coefficient, and the isomorphism of fluorhydroxl ions in the apatite lattice are considered and illustrated by orthogonal projections."
