The following report provides information on the first field work on the radioactivity of Pennsylvanian black shales in Oklahoma and Kansas, 1944, and their findings.

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.

From abstract: "The Geological Survey's program of investigation of radioactive raw materials is presented herewith under present investigations, plans for future investigations, plan of operation, and cost of operation. This report was prepared at the request of the Atomic Energy Commission."

Report discussing investigation of the relation of uranium and phosphate in the Phosphoria formation and its close stratigraphic equivalents.

From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken of these formations and also of 10 ground and surface waters.

The following report summarizes the results of a brief geological examination made by the Geological Survey of the small uranium deposit in the Majuba Hill mine, Pershing County, Nevada.

"This report is a summary of the results of a brief geological examination made by the Geological Survey of the small uranium deposit in the Majuba Hill mine, Pershing County, Nevada."

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.

From Introduction: "This catalog is a list of specimens of radioactive minerals for which the Geological Survey has been collecting optical, X-ray diffraction, and other data."

From abstract: "This report summarizes our knowledge of the geology of radioactive raw materials and outlines the work done by the Geological Survey as well as that planned or recommended. An evaluation of uranium and thorium deposits is given in terms of known reserves and potential resources."

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.

Report discussing the possible existence of pegmatites containing beryllium deposits in the granite stock in the vicinity of Mount Antero and White Mountain, Chaffee County, Colorado.

Report discussing the U.S. Geological Survey's investigation aimed at finding a location with an abundance of black shale, and determining the amount of uranium in the shale.

Report discussing "field and laboratory studies of ground-water conditions in the carnotite-bearing Morrison formation in southwestern Colorado and southeastern Utah" with the objective of determining "possible relations between ground waters and the carnotite deposits."

From introduction: The investigations that are the subject of this report were to appraise the uranium resources of the Red Desert area, and to accumulate data concerning the geology of uranium. Knowledge of the genesis of the schroeckingerite is necessary for a clear appraisal of the deposit.

From abstract: The Geological Survey has been studying the geology of uranium and thorium continuously since 1939, when it began a comprehensive investigation of the vanadium-uranium deposits of the Colorado Plateau. Greatly increased demand for uranium arising from the advent of controlled fission in 1942 resulted in widening of the study in 1944 to include other possible sources and in further expansion on behalf of the U. S. Atomic Energy Commission since 1947. The wide variety of materials investigated in this study are embraced by five somewhat arbitrary groups of related types of deposits as follows: (1) Igneous rocks, pegmatites, veins, and related deposits; (2) Deposits in sandstone of carnotite, copper-uranium, and other minerals; (3) Other consolidated sedimentary rocks; (4) Placers; and (5) Natural fluids.

A report discussing the occurrence and chemical character of ground water in the Morrison Formation in Southeastern Colorado and Southeastern Utah.

From foreword: The six papers included in this report were prepared in an attempt to summarize briefly, and make available to the public, part of the information concerning uranium deposits that is in unpublished reports of work done by the U. S. Geological Survey under the auspices of the Manhattan Engineer District, and later, the U. S. Atomic Energy Commission.

Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.

From abstract: Uranium assays of all the samples collected by the Geological Survey from the Chattanooga shale in east-central Tennessee and southern Kentucky from 1947 to 1949 are assembled here, and conclusions are drawn concerning the distribution of the uranium. The 1108 assays from 80 localities provide reasonably reliable information on the stratigraphic and regional variations of the uranium content.

From introduction: "This report lists in numerical order U.S. Geological Survey Trace Elements Investigations and Memorandum Reports and supersedes a similar report issued in January 1952 (TEI-202)."

From abstract: A comprehensive investigation of the western phosphate deposits, in progress since 1947, involves a study of the Phosphoria and Park City formations over an area of about 135,000 square miles in the states of Montana, Idaho, Wyoming, and Utah0 It was undertaken to acquire more data on the thickness, composition and quality, structure, and distribution of the deposits--data that would help industry select deposits suitable for mining and permit estimation of reserves, evaluation of potential byproduct elements, and establishment of the origin of the deposits.
