A Preliminary Report on Methods of Determining the Age of Colorado Plateau Carnotite
From Abstract: "Four methods of dating Colorado Plateau carnotite have been examined and evaluated: mineralogic methods, radioactive-equilibrium methods, lead-uranium-ratio methods, and lead-isotope methods. The data on 12 high-grade samples, from a suite of 50 representative carnotite ores, are presented."

Conditions of the Formation of Fluorite in Sedimentary Rocks (The Fluorite System)
From translator's abstract: "The formation of fluorite in sedimentary rocks has been investigated by studies of fluorite equilibria in different solutions. Determinations at different temperatures were made on the solubility of crystalline CaF2 in chemically pure water, in aqueous solutions of components of seat water...at different concentrations, and in the sea water itself at degrees of salinity varying from normal to a 15-fold concentration."

Electrical Resistivity Investigations of Carnotite Deposits in the Colorado Plateau
From abstract: An investigation of the use of geophysical methods in prospecting for carnotite deposits in the Colorado Plateau was made by the Geophysics Branch of the U. S. Geological Survey between April 21 and June 24, 1949. Results of this preliminary work indicated that electrical resistivity methods could be used successfully.

The Fluorapatite System of Equilibria in the Conditions of Formation of Sedimentary Rocks
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."

Radioactivity in Some Oil Fields of Southeastern Kansas
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.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California
From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

Progress in Airborne Radioactivity Surveying
From abstract: The objectives in the investigation of airborne radioactivity surveying during fiscal year 1951 were: 1) Establishment of a routine technique of airborne radioactivity surveying -- completed by incorporating those phases of the aeromagnetic surveying technique that were applicable; 2) Development of automatic correction of the radiation measurement for variation in distance from source -- achieved by using the radar altimeter output to modify the output of the counting-rate meter in accordance with the observed variation of radiation intensity with distance from a source; 3) Development of more efficient radiation detectors -- including large scintillation detectors.

The Uranium Occurrences in the Martha E Prospect, Lawson-Dumont District, Clear Creek County, Colorado
From introduction: The Martha E prospect, in Spring Gulch about three and one-half miles southwest of Idaho Springs, Colo. (fig. 1), is on a claim, originally called the Daisy Freese, which was first prospected by the Stanley Mines. The occurrence of radioactive minerals in the adit was called to the attention of the U. S. Geological Survey in 1950 by the owners of the claim. The Survey's Trace Elements Section Washington Laboratory identified metatorbernite, autunite, and sooty pitchblende.
