Abstract: This report consists of four parts, the first three being descriptions of investigations compiled in the period October 1st, 1953 to April 1st, 1954; the fourth part is a summary of progress of the research based on our entire investigations completed prior to April 1st, 1954. The first part comprises a set of preliminary experiments investigating the mineral composition of the sandstones in thin sections, in an attempt to differentiate barren from ore-bearing sandstones. It appears that there are more rock-fragments and particularly more volcanic rock fragments in the ore zone (zone 4, Well C, Bull Canyon). In addition, silica cement appears to be associated with ore and carbonate cement with barren sediments. The second part details the investigation of the mudstones of the Bull Canyon Wells . A mixed layer lattice "illite" and a kaolin mineral are the most prominent in "normal" mudstones. Dye tests suggest there are differences between the clay minerals in the sandstone matrix of the ore zone and barren zone. In addition, the mudstone zones appear to differ in the response to the dye tests. The third part of the report details the bulk density determinations for cores from well B. The results confirm …

Abstract: Weak uranium mineralization is widespread throughout the Uinta Basin of northeastern Utah and northwestern Colorado, in rocks ranging in age from Permian to Eocene. No commercial ore bodies are known, although formations there have characteristics elsewhere considered favorable for ore deposition.

Abstract: An airborne radiometric survey of the Dakota sandstone and Morrison formation in the Canon City embayment was conducted by the Atomic Energy Commission from November 1, 1953 to December 5, 1953.

From introduction: This is one of a series of three reports on airborne radioactivity surveys in the United States. The reports contain the 185 airborne anomaly maps issued by the U. S. Atomic Energy Commission as a result of the AEC's aerial surveying program conducted from March 1952 to June 1956; two ground reconnaissance maps of Utah also are included. Most of the reconnaissance was done in the western United States.

Map showing the proposed drilling area, Coal Creek Anticline, Rio Blanco County, Colorado as part of a United States Atomic Energy Commission, Division of Raw Materials, Exploration Branch report.

Summarizing the data on the uranium-vanadium deposits of the Bull Canyon area in Montrose and San Miguel Counties, Colorado.

A report regarding regional fracture systems mapped for an area of about 90,000 square miles, embracing most of the Colorado Plateau and small strips of the adjoining Rocky Mountains, by the use of aerial photographs and mosaics. The data interpreted from the photographically reduced to produce the final map.

A report regarding uranium deposits of the Urvan Mineral belt.

Determining the major structural features of the area, and the relation between the uranium mineralization along Golden Gate canyon and that of Ralston Creek.

This report discusses the results of an exploration made for uranium sources at the Caribou Mine in Boulder County, Colorado.

The general purpose of the work performed under this contract was to develop geophysical and geochemical methods and techniques which would be effective aides in exploring for uranium and to appraise their effectiveness as determined by the results of field surveys in prospective areas about to be drilled, or in an area where ore is already known.
