Reconnaissance of Some Geologic Formations in Southeastern Idaho, Western Wyoming, and Northern Utah
Abstract: A radiometric reconnaissance, using a portable beta-gamma survey meter, of some geologic formations ranging in age from Cambrian to Cretaceous, and springs in southeastern Idaho, western Wyoming, and northern Utah, has shown that none of them are sufficiently radioactive to warrant further examination of them in the area.

Radioactivity and Mineralogy of Concentrates From the Placers of Julian, Moore, and Candle Creeks and the Cripple Creek Mountains, Lower Yukon-Kuskokwim Highlands Region, Alaska
Abstract: Radiometric and mineralogic study of 10 concentrate samples from the placers of Julian, Moore, and Candle Creeks, and the Cripple Creek Mountains, Lower Yukon-Kuskokwim Highlands region, Alaska, failed to reveal any significant amounts of uranium. Only the sample from Julian Creek shows and appreciable amount of radioactivity (0.03 percent equivalent uranium), but this is attributed entirely to thorium in monazite.

Reconnaissance for Trace Elements in North Dakota and Eastern Montana
From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken of these formations and also of 10 ground and surface waters.

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

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

Trace Elements Reconnaissance of the Southern Highway Belt, South-Central Alaska
Abstract: A radiometric reconnaissance of the areas adjacent to the principal highways and secondary roads of south-central Alaska was carried out during the summer of 1947. The investigation included the examination of nine gold-placer workings, five gold lodes, a gypsum mine, and a copper prospect. Nearly all of the lithologic types outcropping in the highway belt were tested. No significant amounts of radioactive material were found.

Trace Elements Reconnaissance on the South Fork of Quartz Creek, Northeastern Seward Peninsula, Alaska
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 concentrated to be minable.

An Improved Fluorimeter for the Determination of Uranium in Fluoride Melts
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.
