Trace Elements Reconnaissance on the South Fork of Quartz Creek, Northeastern Seward Peninsula, Alaska

Description: Abstract: Two uranium-bearing minerals, uranothorianite and thorite (?), were found in the stream gravels of the main branch of the South Fork of Quartz Creek, a tributary of the Kiwalik River. Although the bedrock source of the minerals was not located, the radioactive material was traced in slope wash well above the stream gravel. A detailed investigation of the area with more sensitive counters might reveal the source of the minerals and localities where the minerals are sufficiently concent… more

An Improved Fluorimeter for the Determination of Uranium in Fluoride Melts

Description: Abstract: The Model R fluorimeter has been modified to increase its stability and sensitivity. The new instrument is about ten times as sensitive as the original fluorimeter, but it can also be employed conveniently at a sensitivity level comparable to or less than that of the Model R fluorimeter.

Radiometric and Mineralogic Studies of the Granitic Complex in the Cape Nome Area Seward Peninsula, Alaska

Description: Abstract: An early report on the Cape Nome area, Seward Peninsula, Alaska, stated that granitic rocks there contain allanite as a common accessory mineral. Results of studies in 1947 indicate that very little allanite is present, and that the slight amount of radioactiity of the granitic complex is attributable to the accessory minerals zircon and sphene.

Carnotite Resources in the Charles T. Area and Vicinity, San Miguel County, Colorado

Description: Report discussing an exploratory drilling program in the Charles T. area and vicinity during the period from November 1947 and September 1949. "The purpose of the exploration was to discover new carnotite deposits to support milling operations on the Colorado Plateau, and to appraise the uranium and vanadium resources of the area explored."

A Preliminary Report on Methods of Determining the Age of Colorado Plateau Carnotite

Description: From Abstract: "Four methods of dating Colorado Plateau carnotite have been examined and evaluated: mineralogic methods, radioactive-equilibrium methods, lead-uranium-ratio methods, and lead-isotope methods. The data on 12 high-grade samples, from a suite of 50 representative carnotite ores, are presented."

Forty-Niner, King Solomon Ridge, and West End Claims Near Clancy, Jefferson County, Montana

Description: Abstract: Secondary minerals of the uranite group occur in dense quartz veins and in altered aplitic granite along and near the crest of the east-trending ridge about one mile west of Clancy, Montana. Brief examination suggests that the radioactive minerals are erratically distributed, but a more thorough study of the area will be made by the Geological Survey during the coming field season.

Potential by-Product Elements in the Phosphoria Formation of the Western States

Description: Report discussing elements that may be by-products of mining or processing phosphate rock. "Many of these elements are of interest because they are essential, if only in small quantities, to plant growth. Others are of concern because they must be removed from the phosphate rock before some of the chemical products manufactured from it can be utilized without deleterious effects."
