Report discussing the relationship between uranium deposits and hypogene mineral zoning in the Front Range mineral belt of Colorado. This report is mostly based on work done by other geologists.

From abstract: Many of the mining districts of the Colorado Front Range mineral belt contain mesothermal sulfide ores that exhibit a zonal distribution. Present data indicate that in most of the zoned districts pitchblende and/or secondary uranium minerals are most abundant in a transition zone between central areas containing predominantly pyritic gold ores and peripheral areas containing dominantly lead-zinc-silver deposits. Copper in the form of chalcopyrite is also probably more abundant in the transition zone than in adjacent zones.

From introduction: "This report is a statement of progress during the six-months period from June 1 to November 30, 1955 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."

A report containing a statement of progress during the six-months period from June 1 to November 30, 1955 on investigations of radioactive materials in the United States and Alaska. The program aims to understand many factors involved in uranium geology.

A report regarding a reconnaissance for radioactive deposits in southeastern Alaska, 1952. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing an investigation of radioactivity occurrences, mostly caused by thorium in thorite and monazite, in various parts of southeastern Alaska. The geology and structural qualities of these radioactive areas are discussed.

A report about a reconnaissance of the Sharon Springs member of the Pierre shale in western Kansas and eastern Colorado was conducted during 1954.

From introduction: The primary objective of these studies is to determine the content and distribution of uranium areally and stratigraphically in the Sharon Springs member of the Pierre shale of Late Cretaceous age.

From scope of report: "The fluorite district in the western part of the Thomas Range, Juab County, Utah, is one f the newest mining districts in western United States; since 1950 it has been the largest producer of fluorite west of the Mississippi River. The present report covers the geology of the entire fluorite producing area, and supplements an earlier report...on the individual mining properties."

A report regarding the geology of the Thomas Range Fluorite District, in Juab 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 the vanadium-uranium deposit at the Rifle and Garfield mines which lies in the Wingate sandstone and the overlying Entrada sandstone.

A report of progress during the six-months period from December 1, 1954 to May 31, 1955 on investigations of radioactive materials in the United States and Alaska.

Discussing the reconnaissance investigation of uranium occurrences in the Saratoga Area, in Carbon County, Wyoming

Report discussing a study exploring regional uranium and other trace elements' relationship to provenance, specifically post-cretaceous origins.

From introduction: This report concerns the investigation of uranium deposits in the Gas Hills area in July 1954.

From abstract: "A method is described for the simultaneous radioassay of the uranium and thorium series and potassium in common rocks, or materials of comparable activity, in which the series are in secular equilibrium. The method is based on the measurement of the counting rate in three bands of the photon energy spectrum derived from the gamma-ray excitation of a scintillation crystal."

A report about five sample of purple fluorite found in association with radioactive materials, and a synthetic colorless control sample which were studies and compared.

Report discussing a reconnaissance search for uranium in shale during August 1953 in western Nebraska and southern South Dakota. The reconnaissance was part of the U.S. Geological Survey's search for uranium in carbonaceous materials.

A report which presents information about the phosphatic parts of the Permian Phosphoria formation and its stratigraphic correlatives sampled in 1953 and 1954.
