Report discussing the Shinarump Conglomerate, the channels leading to this conglomerate, and the uranium minerals which localize at the base of this conglomerate via the channel sediments. The geology of the area, information on the channels, and information regarding the localization of uranium in channels are included.

Abstract: Tables of decay constants and functions thereof are presented to simplify the problem of calculating the constants involved in the Bateman equation. An alternate method of solving for the amounts of the nth member of a radioactive series is given in the form of a power series.

Report discussing the investigation of 750 square miles of land in Wyoming aimed at locating uranium deposits. Information regarding the area, uranium deposits, mineralogy, and results of the exploration are included.

From abstract: Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities with abnormally high radioactivity were found; uranium minerals are visible at 121 of these localities.

From introduction: This report describes the general geologic setting, the occurrences of uranium or radioactivity in the Fall Creek, Idaho area and adjacent areas, the probable nature of the mineralization and origin of the deposits, and the estimated reserves of uranium-bearing rock.

Report discussing the geology and uraniferous carbonaceous rocks found in the Bear River of the Fall Creek area of Bonneville County, Idaho. The report provides information regarding the geology of the area, uranium occurrences, distribution of uranium and other elements in carbonaceous materials, origin of uranium occurrences, core drilling results, and inferred reserves.

Report discussing an investigation of radioactivity in part of Clear Creek County, Front Range, Colorado. The methods and results of the reconnaissance are included. Veins containing chalcopyrite were found to be the best source of radioactivity in the region.

A report about a previously published semiquantitative spectrographic method that was modified by applying microphotometric scanning of the spectrograms in such a way that the operator was free to do other work during a large part of the scanning time.

A report about uranium bearing lignite beds which are 1.5 to 8 feet thick that occur in the Fort Union formation of the southern part of the Ekalaka Hills, Carter County, Montana.

From introduction: This bibliography is an annotated list of selected reports that were publicly available as of May 31, 1956, pertaining to the uranium content and/or radioactivity of igneous and metamorphic rocks and minerals in the United States.

A report regarding localization of uranium minerals in channel sediments at the base of the Shinarump conglomerate, Monument Valley, Arizona. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing the U.S. Geological Survey's analysis of radioactive rocks collected from Nevada before 1952.
