The following report covers investigations of uranium and thorium discovered within host minerals in the earth's crust, zircon, sphene, apatite, epidote, and monazite. The object of this investigation has been to obtain an approximate measure of the abundance and distribution of uranium and thorium among these five mineral phases.

Report discussing the U.S. Geological Survey's investigation of carnotite deposits found at Club Mesa, Colorado.

Report discussing the U.S. Geological Survey's exploration from 1949 to 1951 of carnotite deposits in Outlaw Mesa, Colorado.

A report regarding carnotite resources of Outlaw Mesa, Mesa County, Colorado.

A report

Report discussing "a direct comparison of helium and lead in nonmetamict zircon crystals".

From abstract: Incomplete but recently partly revised estimates indicate the presence of about 10 billion tons of phosphate deposits in the Urited States that is minable under present economic conditions. Deposits too lean in quality or thickness to compete with those in the western and southeastern fields probably contain tens of billions of tons.

Report discussing the investigation of the chemical composition of sandstone-type uranium ores and unmineralized sandstones of the Colorado Plateau. Spectrographic and chemical analyses was used.

An index and geological map of Nevada's Plutonium Valley quadrangle in Nye and Lincoln Counties, Nevada

From introduction: This report is a summary of geologic information obtained by the USGS at Dolomite Hill, Nevada.

Discussing the geology of the Midnite Mine Area, in the Spokane Indian Reservation

From introduction: The gravity survey of the Nevada Test Site and contiguous areas of southern Nevada and southeastern California has been made by the U.S. Geological Survey on behalf of the U.S. Atomic Energy Commission. The objective of this study is to delineate and interpret gravity anomalies and regional trends so that the configuration and depth of the buried erosional surface of the Paleozoic rocks may be determined.

From Introduction: "This summary lists the Geological Survey's current and future investigations of uranium and other elements of related interest."

Report discussing studies on the molybdenum blue reaction and the determination of phosphorus in waters containing arsenic, germanium, and silicon. Experimental methods and data are included.

From abstract: "Sediments of the inner part of the southern Atlantic Coastal Plain have been sampled and examined for monazite." The report provides sections on general geology, field and laboratory methods, distribution of monazite, and other mineral products.

A report regarding monazite in part of the southern Atlantic Coastal Plain. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

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)."

A report about how minor- and trace-element content of sulfides associated with uranium ore deposits from sandstone-type deposits have proved that selenium commonly substitutes for sulfur.

The following report summarizes descriptive geological and lithological data for the U12i tunnel system in the Nevada test site.

A report outlining the geology of the U12i and U12i.01 tunnels and the lithology of the U12i.01 drill hole, located at a Nevada test site. Prepared on behalf of the U.S. Atomic Energy Commission.

A report about the occurrence, distribution, and quantities of beryl and other strategic minerals in pegmatites located in the Newry Hill area, Maine.

An index and geological map of Nevada showing the Yucca Flat quadrangle.

Report discussing a stratigraphic study of the Morrison and related formations of the Colorado Plateau Region to "determine the paleogeography of the uranium-bearing formations of the Colorado Plateau" and "provide a sound foundation for stratigraphic nomenclature within the areas of geologic mapping and exploration programs."

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.
