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".

A report regarding development drilling in the Ellison-Burro claims area, Slick Rock District, San Miguel County, Colorado

Report discussing development drilling on the Ormalian Group, Paradox District, Montrose County, Colorado.

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.

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 abstract: These results demonstrate that the self-potential method is not satisfactory for locating and delineating sulfide-bearing uranium ore bodies under conditions similar to those in the Happy Jack area.

From introduction: The Trace Elements Section Washington Laboratory had developed the methods used in anticipation of handling an increased volume of water analyses as this preliminary project is expanded into a full-scale investigation. The efforts of these groups were coordinated by the Trace Elements Planning and Coordination Office.

Introduction: Field work during the 1952 field season has supplied new data on the areal extent, composition, and estimated reserves of uranium-bearing carbonaceous rocks in the Fall Creek.area, Bonneville County, Idaho. The following is a preliminary report of progress to describe these new data which supplement the information contained in Trace Elements Memorandum Report 340 (Vine and Moore, 1952). This work was done on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission.

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.

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