Report discussing the use of chemical concentrations of certain elements in uranium deposits of the Colorado Plateau as a guide for the size of the deposits.

A report regarding chemical composition as a guide to the size of uranium deposits in the Salt Wash member of the Morrison formation, Colorado Plateau

Report discussing a study of the distribution, volume, and lithologies of sedimentary rocks of the Colorado Plateau, and of the distribution of elements contained within these rocks.

The following is a semiannual progress report, preliminary in nature, covering work done in the period of December 1, 1958 to May 31, 1959.

From introduction: Approximately fifty radioactive deposits and nearly fifty properties not abnormally radioactive were examined during a geologic reconnaissance for radioactive minerals in Idaho, Washington, and western Montana during the period July 1952 -- June 1955. The most important uranium deposits are in or near granitic to quartz monzonitic intrusions of probable Cretaceous age in central and northern Idaho, westernmost Montana, and northeastern Washington. The purpose of these reports is to describe the geology of the areas so that the possibilities for the disposal of high-level radioactive fluid waste in deep wells can be ascertained.

From introduction: This report details the results of instrument recordings of a nuclear explosion where ground zero was near the top of Rainier Mesa.

This report presents results of a geological study of the Little Cone quadrangle in southwestern Colorado, as well as information on the mineralogy of the location.

From foreword: This report details geologic investigations of radioactive deposits in the United States.

Abstract: "In this report is assembled the available information about the dissociation and melting of the alkali and the alkaline earth carbonates and the binary systems they form with each other. Information is also included about the oxides formed on dissociation of the carbonates, and when it exists pertinent information about the effect of water. Because the carbonates are compounds in binary systems that contain the volatile CO2 component, the report contains a discussion of the complicated phase equilibrium relations in systems in which a compound is formed between volatile and nonvolatile components, including a discussion both of systems in which the solubility curve does not and does intersect the critical curve."

The following report covers the study of the Chattanooga shale and Maury formation found between the Nashville Basin and the surrounding Highland Rim.

This report analyzes the characteristics of three vanadium-uranium ores of the Colorado Plateau by prevalence of a number of low-valence vanadium oxide minerals, usually occurring as fine-grained mixtures. The ores being analyzed are haggite, doloresite, and duttonite.

The following report covers detailed investigations on botanical methods of prospecting for uranium that have been developed on the Colorado Plateau by the U.S. Geological Survey.

Report discussing the geochemistry of uranium in phosphorites and black shales of the phosphoria formation, with the assumption that the immediate source of the uranium in the Phosphoria formation was the ocean.

The following report is based mainly on information obtained from lithologic and gamma-ray logs of drill holes in the Lakeland Highlands area and Clark James-South Ridgewood.

A report about selenium which can be determined in pyrite, chalcocite, and marcasite by a spectrochemical method that is simple and rapid, and that requires no complicated arrangement of spectrographic equipment, or chemical pretreatment of samples.

Report establishing the tentative scope of a comprehensive report entitled "Geology of uranium bearing vein deposits in the United States," defining for use in the comprehensive report several geologic terms that are used differently by different geologists, establishing a tentative classification of uranium-bearing veins, and summarizing available data on the geographic and geologic distribution of uranium-bearing veins.

"This report is part of the introductory chapter of a comprehensive report on the geology of uranium-bearing veins in the United States which is being prepared for publication by the Geological Survey."

The following report describes preliminary investigations on the use of controlled atmospheres, discussing the method of semiquantitative spectrographic analysis used in conjunction with the final gas jet design.

The following report discusses the chemistry and mineralogy investigations on vanadium oxides.

The following report discusses a method that was developed for the determination of calcium in phosphate, carbonate, and silicate rocks using the Beckman flame photometer, with photomultiplier attachment.

The following report discusses a method for determining lead in monazite to be used as a basis for geologic age measurements. In order to develop the method it was necessary to eliminate interferences due to the presence of phosphates of thorium and the rare-earth metals.

From introduction: This report summarizes the results of the USGS exploration in the Yellow Cat and Squaw Park areas, and contains a brief description of the geology and ore deposits

Report discussing an exploration for uranium and vanadium deposits in the Yellow Cat and Squaw Park areas in the Thompson Park district of Grand County, Utah. The exploration occurred from October 8, 1951 to November 23, 1954.

The following report is a statement of progress during the six-months period from December 1, 1955 to May 31, 1956 on investigations of radioactive materials in the United States and Alaska, undertaken by the U.S. Geological Survey under the sponsorship of the U.S. Atomic Energy Commission.
