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 an investigation of radioactive Chattanooga black shale found in east central Tennessee.

Abstract: The Control Chart statistical methods, developed by Showhart for the control of quality of manufactured products, are applied to the control of Geiger-Miller counting instruments. Experiments are reported to show the use to the Control Chart method for detecting disturbances in instrumental behavior and for detecting radioactive effects so weak that they are near the limit of detection of the instruments. As a corollary, the control chart can be used to reduce to its practical limit the time required for tests.

From Abstract: "This paper describes a rapid routine procedure for the determination of phosphorous in the presence of vanadium. Vanadium is reduced with formic acid prior to precipitation of phosphorous as ammonium phosphomolybdate and the ammonium phosphomolybdate is weighed as such."

Report discussing a procedure for determinion of thorium in monazite ores and other ores with diverse composition. This procedure can be used for high and low grade ores.

From abstract: "This paper describes a quantitative fluorimetric method for the determination of small amounts of uranium..., useful for field and laboratory."

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 was undertaken to overcome poisoning difficulties that are caused by passage of solutions containing nickel through the Jones reductor/zinc amalgam reductors.

Report discussing an Chattanooga shale adit for laboratory test samples of rock and gaining information regarding mining conditions.

From abstract: This is a review, with annotated bibliography, of the mode of occurrence of the element beryllium. It is not a list of specific ore deposits, but a summary of the types of the types of minerals and rocks in which beryllium has been reported to occur. In addition, the unpublished spectrographic studies of the Geological Survey on mill products are summarized, and data are given on domestic production and reserves and on foreign production.

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

The following report discusses the possible sources of the uncommon element, germanium. It is the first in a series of reports to be prepared by the Geological Survey discussing rare and uncommon elements.

This report is the second in the series of reports carried by the Geological Survey on rare or uncommon elements and their possible sources. The report discusses xenon, an element belonging in a group of elements known as the inert gases, characterized by its lack of reactivity.

A report regarding pegmatites of the Errington-Theil mine, Elko County, Nevada.

This report follows a preliminary geophysical investigation that was made in the Colorado-Utah Plateau in search of carnotite ore deposits.

Report outlining fields of study for a program of research in the geochemistry of uranium. From Abstract: "Various specific topics and projects that apply to these fields of study are suggested."

The following report provides a summary of detailed procedures and methods given to small quantities (as low as 0.10 mg) of thorium in rocks and ores.

The following report covers the process of field measurement of radioactivity with a limited screening process of activity equivalent to 0.005 percent of uranium in equilibrium with its disintegration products.

The following report provides a summary and the methods of the experimental work given with a small percentage of thorium oxide.

Abstract: Procedures are presented in detail of two methods for the determination of very small percentages of uranium (down to 0.002%). The methods are applicable to a wide variety of materials. Notes on the methods and confirmatory experiments are also given.

The following report is based on the findings of a Geological Survey party who spent one week during July 1944 in western North Carolina testing some of the Pegmatites and one Kyanite mine of that region for radioactive minerals.

The following report provides information and results of an investigation on heavy mineral concentrates available in the placer deposits of North Carolina during the summer of 1946.

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.
