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."

Report discussing elements that may be by-products of mining or processing phosphate rock. "Many of these elements are of interest because they are essential, if only in small quantities, to plant growth. Others are of concern because they must be removed from the phosphate rock before some of the chemical products manufactured from it can be utilized without deleterious effects."

From abstract: "A study was made of the important factors in the 'direct' fluorimetric determination of uranium in the range 0.0005 to 0.08 micrograms of uranium, and a modified procedure based on these results is given."

Report discussing a study on "the relation of plants to carnotite deposits in several districts of the Colorado Plateau...Basic geobotanical studies were made largely in the Yellow Cat district, near Thompson, Grand County, Utah."

Abstract: "Comparative data are presented on separations of microgram amounts of uranium from milligram amounts of various metal ions with Na2Co3-K2CO3, Na2CO3-K2CO3-H2O2, and Na2CO3-NaClO. The Na2CO3-K2CO3 separation procedure is applied to the analysis of shales, lignites, and monazites. This method will determine as little as 0.001 percent uranium in shales and lignites and 0.01 percent uranium in monazites."

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."

Report describing a nomogram for calculating percent composition from mineral-grain counts. From abstract: "A nomogram for calculating percent composition from mineral-grain counts reduces several of the more tedious arithmetical operations to two mechanical ones."

From abstract: The Permian marine phosphorite deposits of the western United States were laid down in the Phosphoria formation and its partial stratigraphic equivalents over an area of about 135,000 square miles in Montana, Idaho, Wyoming, Utah, and Nevada. The deposits in the eastern part of the field lie on the western margin of the structurally simple North American craton.

Report describing the phosphorite deposits of the western United States with the objective of outlining features that are common to both the Kara Tau phosphorite deposits of Russia and the western United States deposits in an effort to define their origin.

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.

Purpose: The main objective of the Dakota core drilling program was to determine reserves of uraniferous lignite based on chemical uranium and spectrographic determinations from unweathered samples, particularly from those areas where surface sampling of the beds during the previous field season indicated that significant deposits of uranium-bearing lignite might be present. A secondary objective was to obtain fresh samples and to measure the radioactivity of the overlying Oligocene White River and Miocene Arikaree formations from which the uranium in lignite is believed to have been derived.

From Abstract: "A qualitative spectrographic method of analysis of single mineral grains, impurity inclusions, X-ray powder spindles, and other small samples weighing 1 mg or less is described."

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.

Report discussing a study of the crystal structure of montroseite crystals. Results of X-ray study, crystal structure analysis, features of the structure, and crystal chemistry and alteration information are included.

Report discussing a geological study that took place from January 1952 - April 1953 to determine the habits, ore controls, and possible origins of the uranium deposit of the Shinarump No. 1 mine, which is located approximately 12 miles northwest of Moab, Utah.

A report regarding the geology of the Shinrump No. 1 Uranium Mine, Seven Mile Canyon Area, Grand County, Utah. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report about an improved transmission fluorimeter for use in the determinaton of uranium which consists of a line-operated, low-voltage d-c supply, powering a small 3-w ultraviolet lamp as a source of long wavelength ultraviolet radiation.

Report explaining a multiple cone sample splitter, which, in one operation, obtains representative sample fractions of 5-50 percent and increases time efficiency compared to conventional methods of sample splitting. Information regarding the machine's description, operation, and accuracy are given as well as a summary.

Report discussing the investigation of zeunerite-related radioactivity and molybdenite-related radioactivity occurrences in the lower Yukon-Kuskokwim region, Alaska. Discussion of the data, methods and purpose of investigation, and location of radiation are included.

Report discussing a geological examination conducted during the summer of 1949 of the Fairbanks and Livengood quadrangles of east-central Alaska to determine the presence of radioactive materials.

Report discussing the U.S. Geological Survey's investigation of the stratigraphy of the Phosphoria formation in Montana. Abstracts of stratigraphic sections and analytical data is included.

Report discussing the various resources of lithium for the United States and Canada. The report contains information regarding the geology of lithium in the U.S. and Canada, lithium reserves and resources, and the future of the lithium mining industry.

Report discussing the intensive search for uranium in the United States. This report contains information regarding common uranium minerals, types of uranium deposits, methods of prospecting for uranium, distribution of uranium deposits in the United States, and a conclusion.

A report discussing a spectrophotometric study of thorium's reaction with morin in solutions of pH 2.0, which yields a single yellow complex with a ratio of 1 thorium:2 morin.
