The following report provides a geologic map of the Thirsty Canyon quadrangle in Nye county, Nevada.

Report containing geologic and vein maps for part of the Central City District, Colorado. Tables containing Shafts and adits in the area are included.

The following report covers a reconnaissance for radioactive materials that was made in parts of Maine, New York, New Jersey, and Pennsylvania. It's primary objective was to examine the iron ore deposits and associated rocks in Adirondack Mountains of New York and the Highlands of New Jersey. Additionally, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. However, most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in tables provided.

Abstract: "Crandallite ores may be useful in the treatment of nuclear waste solutions because of their reactivity with strontium in weakly acid solutions and in alkaline solutions containing aluminum. The exchange capacity of the crandallite samples studies is not very high, being 6-10 miliequivalents of strontium and 2 milliequivalents of cesium per 100 grams of active phosphatic material. However, strontium removal is many times more effective from alkaline solutions, precipitation being the dominant mechanism. The removal of strontium is even more complete in alkaline solutions containing aluminate ions."

This report is a statement of progress during a six-months period and gives the principal unclassified information developed in that period about investigations of radioactive materials in the United States and Alaska, and to a minor extent in foreign countries.

A report about uranium analyses and uranium distribution in the United States.

Report discussing the use of chemical concentrations of certain elements in uranium deposits of the Colorado Plateau as a guide for the size of the deposits.

Report discussing progress made on various research projects to determine the location and geology of radioactive deposits during the period from December 1, 1952 to May 31, 1953.

Report discussing a geological examination of the Upper Porcupine River in northeastern Alaska to find radioactive materials.

The following report is a statement of progress during the six-months period from December 1, 1955 to May 31, 1956 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.

Report discussing a study in which uranium-bearing lignite was mapped and sampled in the Bullion Butte, Sentinel Butte, HT Butte, and Chalky Buttes areas in southwestern North Dakota.

The following report analyzes the physical behavior of radon concentrations in streams and related spring waters in the Wasatch Mountains near Salt Lake City and Ogden, Utah, to determine the relationship between the distribution of radon and its geologic environment.

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.

This report analyzes the characteristics of three vanadium-uranium ores of the Colorado Plateau by prevalence of a number of low-valence vanadium oxide minerals, usually occurring as fine-grained mixtures. The ores being analyzed are haggite, doloresite, and duttonite.

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

Report discussing a study on secondary radioactive iron minerals closely associated with uranium and thorium deposits in various western states. From abstract: "A study on these radioactive 'limonites' was therefore undertaken in an attempt to find out in what form the radioactive material is present in the limonite, how it was introduced, and whether a field study of leached ferruginous cappings over uranium and thorium deposits might yield information about the depth, distribution, size, and grade of underlying ore bodies."

Report discussing a 1948 geological examination of 7,662 miles of roadside rocks in Vermont, Connecticut, Rhode Island, and southeastern New York to find deposits of radioactive materials.

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.

The following report follows geological investigations made on the 410 Area of the Nevada Test Site.

Report discussing reconnaissance for radioactive materials in parts of Maine, New York, New Jersey, and Pennsylvania during 1952. From Abstract: "The primary objective was to examine the iron ore deposits and associated rocks in the Adirondack Mountains of New York and the Highlands of New Jersey."

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Report discussing different types of uranium deposits found in Colorado mines and the geological guides which can help locate these deposits.

The following report covers the study of the Chattanooga shale and Maury formation found between the Nashville Basin and the surrounding Highland Rim.

Report discussing an exploration for uranium and vanadium deposits in the Yellow Cat and Squaw Park areas in the Thompson Park district of Grand County, Utah. The exploration occurred from October 8, 1951 to November 23, 1954.
