From abstract: The White Oak quadrangle lies near the western edge of the eastern Kentucky coalfield and includes approximately 59 square miles of parts of Magoffin and Morgan Counties, Ky. The outcropping rocks are equivalent to most of the Breathitt formation of Pennsylvanian age. The regional southeast dip of the rocks is interrupted by the Irvine-Paint Creek fault, the Caney anticline, the Grape Creek syncline, and the Johnson Creek fault.

A report about geologic names. It contains new names, old names, and changes to names.

This report sumarizes the results of the US geological survey exploration in the Bull Canyon district from October 1955 to April 1956

From introduction: This report is based on investigations carried on by the Geological Survey (U. S. Department of the Interior) under the auspices of the Interdepartmental Committee on Scientific and Cultural Cooperation (U. S. Department of State) and the Foreign Economic Administration. The function of the last two agencies is presently carried on by the International Cooperation Administration. Roberts is responsible for the text of this report and for the compilation of the geologic map. He was in Central America from January to April 1942 under a program of scientific and technical cooperation with the American Republics sponsored by the Department of State, and mapped manganese deposits in Costa Rica and manganese and antimony deposits in Honduras.

Abstract: The uranium deposits of the Colorado Plateau contain suites of minerals that are the result of different stages of oxidation of deposits with different elemental composition. A classification based on composition and stage of oxidation is presented.

From introduction: This report describes the results of reconnaissance for radioactivity of rocks, exclusive of coal, in the States of Rio de Janeiro, Sao Paulo, Parana, Santa Catarina and Rio Grande do Sul during the years 195 through 1956. Reports on reconnaissance and detailed studies of uraniferous coal are being prepared for publication. This report concerns work performed by the Brazilian National Nuclear Energy Commission and the United States Geological Survey (on behalf of the United States Atomic Energy Commission), and it is published with the permission of these agencies.

The following report describes samples of simplotite, a new calcium tetravanadite, that was discovered in five vanadium-uranium mines in the Colorado Plateau.

From abstract: Uraniferous coal has been found in northeast Parana', Brazil, in the Rio Bonito formation of Pennsylvanian age. In the majority of coal samples taken the uranium oxide content ranges from 0.005 to 0.030 percent, but selected screened samples have contained as much as 0.45 percent uranium oxide. The sampled thickness of the coal seam ranges from 17 to 54 centimeters and averages 31 centimeters. Channel samples across the entire thickness of the coal zone were taken in two places. All other samples were taken as grab samples from either mine waste dumps or coal zones that had high radioactivity.

Abstract: Uraniferous rock was discovered in the Phillips mine-Camp Smith area in 1953. Precambrian rocks of the Hudson Highlands of the New England physiographic province underlie the area.

Report discussing uranium that was discovered in uraniferous rock in the Phillips mine-Camp Smith area of New York in 1953.

The following report covers investigation work done on the distribution of thick deposits of salt that had occurred in the Paradox member of the Hermosa formation of Pennsylvanian age in an area nearly 12,000 square miles of southwestern Colorado and southeastern Utah.

A report regarding the distribution and thickness of salt in the paradox basin of southeastern colorado and southeastern Utah. This report concerns work done on behalf of the Division of research of the U.S. Atomic Energy Commission.

The following report studies the occurrence of the vanadium oxide mineral, doloresite, that has been identified in 11 mines on the Colorado Plateau.

A report about drill holes in uranium in the Todilto limestone of Late Jurassic age near New Mexico which does not yield duplicate gamma-ray logs when probed at different times.

The following report studies a rare-earth deposit in the Scrub Oaks iron mine, Morris County, New Jersey, that was mapped and sampled in the 1955.

The following report describes the study of the hydrous uranium-molybdenum mineral umohoite discovered in the Lucky Mc mine, Wyoming.

This paper concerns work done by the U.S. Geological Survey on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

The following report covers the study of electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting.

From introduction: This report contains the results of a detailed geological and uranium deposits study made of the Monument Valley.

Abstract: "Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part of the Tertiary. The individual ages determined on zircon from 2 rocks from southeastern Alaska and 1 from east-central Alaska gave results of 90, 100, and 96 million years; those determined on 4 rocks from central Alaska gave results of 47, 56, 58, and 51 million years."

Report discussing the contact and weathering of the Burro Canyon formation shales and Dakota sandstone as well as other connections of the Burro Canyon formation.

The following report covers measurements of electrical resistivity and dielectric constant that were made on parts of 27 cores from the Morrison formation in the Colorado Plateau uranium province as part of a program to obtain basic data on the physical properties of the rock in and near uranium-mineralized zones.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.
