A report about a new uranium mineral from the Fuemrol No. 2 mine, Emery County, Utah, named abernathyite.

A report about the ages of the four great batholiths in the western United States.

Introduction: Deposits of phosphate in Florida, located beyond the limits of known producing areas, have been reported by prospectors and mining companies. Much of the information has been based upon prospecting and exploration which was undertaken many years ago and as a result the published data relating to the occurrence of these deposits are fragmentary, and few details relating to specific locations and extent are available.

Report discussing airborne radioactivity surveys, aimed at finding uraniferous phosphate deposits, in ten areas of Florida. A subsequent ground investigation of two radioactivity anomalies out of eight was conducted. Information on radioactivity measurements for each area is given as well as conclusions.

The following report describes the use of airborne radioactivity surveying and analytical techniques in geologic exploration by examples of the analysis or evaluation of airborne data related to specific geologic settings. The airborne radioactivity surveying program was begun in 1949 by the U.S. Geological Survey to assist in uranium exploration.

Report discussing a study of 1,000 Gamma-ray logs of oil wells in the central part of the United States which confirmed the use of these logs for the detection of radioactive deposits.

Report discussing a study in which "thorium nitrate is quantitatively extracted by mesityl oxide from solutions saturated with aluminum nitrate even in the presence of relatively large amounts of phosphate."

Report discussing the geography and ores of the Spud patch area, which acted as a source of carnotite ore from deposits in a sandstone lens.

Report discussing a geological study of the Chattanooga Shale of the Eastern Highland Rim area of Tennessee in 1947, 1948, and 1949 to determine its availability as a source of uranium.

Abstract: "Thickness, grade, and depth data were obtained by analyzing gamma-ray logs and core samples from 56 diamond drill holes penetrating uranium deposits in the Colorado Plateau. The data from the two methods were compared to determine variations found in gamma-ray log interpretation and chemical and radiometric analyses of the drill core. Correlations within each parameter varied among the drilling areas analyzed. Gamma-ray interpretations of grade compared to chemical analyses were within the range of -10 to +25 percent. Most depth measurements determined by gamma-ray log interpretation compared to drill core measurement were within 0.5 percent. Results of the study indicate a need for better thickness definition in both gamma-ray logging and core scanning equipment."

Report discussing the sources of about 1,400 samples of samples of mine, mill, and smelter products that were collected by the U.S. Geological Survey. In addition, the "kind of material sampled, i.e. ores, concentrates, middlings, tailings, flue dusts, and so forth, and the radioactivity of the samples are listed in the report."

From introduction: This report details mineral and chemical relations in two uranium-vanadium ores of the Colorado Plateau.

The following report analyzes channel samples from two mines (Mineral Joe No. 1 and Virgin No. 3) on the Colorado Plateau that have been studied in detail both mineralogically and chemically.

The following report is the result of a reconnaissance of the black shales of the Eastern United States in the summer of 1944. The purpose of this reconnaissance was to determine the radioactivity of the shales, specifically for uranium and thorium.

The following report covers investigations on radioactivity in copper-bearing iron oxide mineralization fissures and fractures in narrow zones within Kobuk River Valley, Alaska.

Report discussing the U.S. Geological Survey's exploration aimed at locating uranium-vanadium deposits of the Beaver Mesa area. The report provides information regarding the geology of the area, uranium-vanadium deposits, the U.S. Geological Survey's exploration, reserves, and plans/recommendations.

A report regarding exploration for uranium-vanadium deposits in the Beaver Mesa area, Mesa County, Colorado, and Grand County, Utah. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

From abstract: "A method is described whereby aluminum in phosphate rock is determined by the fluorescence of aluminum hydroxyquinolate in chloroform solution."

Abstract: Secondary minerals of the uranite group occur in dense quartz veins and in altered aplitic granite along and near the crest of the east-trending ridge about one mile west of Clancy, Montana. Brief examination suggests that the radioactive minerals are erratically distributed, but a more thorough study of the area will be made by the Geological Survey during the coming field season.

Report discussing geologic structures which localize carnotite deposits of the Colorado Plateau.

Geologic maps and structure sections of the Johnson Creek Quadrangle in Caribou County, Idaho. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report about the Central City district and adjoining mining areas in the central part of the front range mineral belt which has supplied small quantities of uranium ore intermittently since the discovery of pitchblende at Central City in 1871.

Report discussing geophysical observations in parts of the Grants district of McKinley County, New Mexico. This study had the "dual objective of investigating the unusual occurrence of negative aeromagnetic anomalies in close association with airborne radioactivity anomalies, and of investigating other geophysical methods which might assist directly or indirectly in the search for uranium ores in the Grants district."

Report discussing the progress made on a continuing geophysical program during the period from January to April, 1959. The purpose of the program was to determine the type and configuration of various rock units below the surface in areas of interest at the Nevada Test Site.
