Revisions in Stratigraphic Nomenclature of the Columbia River Basalt Group

Description: From abstract: New stratigraphic nomenclature for units within the Columbia River Basalt Group is introduced to revise and expand that currently in use; it is based largely on subdivisions made informally by T. L. Wright, M. J. Grolier, and D. A. Swanson in 1973. The Yakima Basalt is raised to subgroup status, and three formations-the Grande Ronde Basalt, Wanapum Basalt, and Saddle Mountains Basalt, in order of decreasing age-are defined within it.

Geology of the Pennsylvanian and Permian Cutler Group and Permian Kaibab Limestone in the Paradox Basin, Southeastern Utah and Southwestern Colorado

Description: From abstract: This report talks about the geology of the Pennsylvanian and Permian Cutler Group that consists of the lower Cutler beds, Cedar Mesa Sandstone, Organ Rock Formation, White Rim Sandstone, and De Chelly Sandstone. The report also talks about the Permian Kaibab Limestone in the Paradox Basin that overlays the Cutler.

The Stratigraphy of the Upper Part of the Bone Valley Formation and its Relation to the Leached Zone

Description: From abstract: The two topmost zones of the Bone Valley formation at the Homeland mine are a phosphate-cemented quartz sandstone and an underlying pebbly and clayey quartz and phosphate sand characterized by graded bedding. This sequence is found in every other area of the land-pebble field. Therefore, these zones are considered to be stratigraphic units and the transition between them to be a key horizon.

Stratigraphy of Outcropping Permian Rocks in Parts of Northeastern Arizona and Adjacent Areas

Description: From introduction: In the spring and early summer of 1950 the writers undertook an investigation of the outcropping Permian rocks in northeastern Arizona, northwestern New Mexico, and parts of southern Utah. This work had as its specific objective the establishing of correlations of Permian rocks in the Zuni uplift, Defiance uplift, and Monument Valley upwarp. The determination of these relations, it is believed, will be of aid in the current activities of the Geological Survey in the Navajo Reservation which have as objectives the investigation of the mineral fuels and water resources of the area.

Preliminary Study of Uranium Favorability of the Wilcox and Claiborne Groups (Eocene) in Texas

Description: From introduction: This report presents the results of a preliminary study of the uranium favorability of lower and middle Eocene rocks in the Wilcox and Claiborne Groups in the Texas Gulf Coastal Plain. The project began October 1, 1976, and was completed March 1, 1977, by personnel of Bendix Field Engineering Corporation (BFEC) under the auspices of the U.S. Energy Research and Development Administration (ERDA).

Geology, Soil, and Climate at Specific Points Throughout the World, Volume 2: Europe, U.S.S.R., and Southwest Asia

Description: This is part of a series of reports that cover the study of 202 sites throughout the world providing data on rock and soil to a depth of 100 feet and on climatic conditions. This volume discusses locations in Europe, the U.S.S.R. and Southwest Asia.

[Evolution of Sedimentary Basins--Uinta and Piceance Basins: Chapters H and I]

Description: From abstract: Analysis of vitrinite reflectance profiles and surfaces of equal vitrinite reflectance in the southeastern part of the Piceance basin, northwestern Colorado, indicates that burial histories for the Divide Creek anticline and the Grand Hogback are different from those for adjacent synclines. These two positive structures probably reached their present-day thermal maturity before late Eocene folding and before the end of the Laramide orogeny. In contrast, adjacent synclines did not reach their present-day thermal maturity until the end of the Laramide orogeny, or possibly later.

Preliminary Report on Uranium-Bearing Pliocene (?) Rocks in the Split Rock Area, Central Wyoming

Description: From abstract: A sequence of slightly radioactive Pliocene(?) rocks in the Split Rock area of central Wyoming is at least 600 feet thick, underlies an area of more than 25 square miles, and consists of alternating beds of tuffaceous shale, sandstone, and pumicite. Only a small part of the section has been examined. In addition to the uranium content of the strata, there has been secondary concentration of uranium in brecciated limestone similar to spring deposits that could be of Pliocene or Pleistocene age.

Jurassic Rocks of the Zuni Uplift, New Mexico

Description: From abstract: The stratigraphy and structure of the Jurassic rocks of the Zuni Uplift and adjacent areas of northwestern New Mexico were studied by geologists of the U. S. Atomic Energy Commission during the Spring and Summer of 1951. Emphasis was placed upon deposits in the vicinity of Grants, New Mexico.

Preliminary Study of the Uranium Potential of the Triassic Sanford Basin and Colon Cross Structure, North Carolina

Description: From summary: A preliminary geologic investigation was conducted to determine if the Triassic sedimentary rocks of the Sanford basin and Colon cross structure in North Carolina are favorable hosts for uranium deposits. Rocks of the adjacent Carolina slate belt were also examined as a potential source of uranium

Preliminary Report on the Geology and Uranium Deposits at Temple Mountain and Green Vein Mesa, San Rafael Swell, Emery County, Utah

Description: From abstract: In 1953 the U. S. Geological Survey started the present program of uranium investigations on behalf of the U. S. Atomic Energy Commission in the San Rafael Swell, Emery County, Utah. Two areas within the Swell were selected and studied; one in the vicinity of Temple Mountain and the other at Green Vein Mesa.

Late Mesozoic and Cenozoic Stratigraphic and Structural Framework Near Hopewell, Virginia

Description: From introduction: This study was undertaken as part of the U.S. Geological Survey's (USGS) Reactor Hazards Reduction Program. One of the goals of this program is to contribute to the growing recognition and cataloging of Cenozoic faults in the Atlantic Coastal Plain. Once the faults are recognized and cataloged, the stress field and resulting tectonic framework that produced these faults can be determined. This study defines the stratigraphic and structural relationships of a tectonically anomalous area in the vicinity of Hopewell, Va.

The Frontier Formation and Associated Rocks of Northeastern Utah and Northwestern Colorado

Description: From abstract: The Frontier Formation of the Mancos Group in northeastern Utah and northwesternmost Colorado (proposed new rank designations; formerly known as the Frontier Sandstone Member of the Mancos Shale) consists of several facies of marine and nonmarine rocks of Late Cretaceous (Turonian) age that grade eastward into totally marine rocks in easternmost Utah and northwestern Colorado.

Geology of the Kettleman Hills Oil Field, California: Stratigraphy, Paleontology, and Structure

Description: From Introduction: The field work that furnished the basis for this report was begun in 1930 and was continued at intervals until 1934. The anticlinal character of the Kettleman Hills is apparent to even the casual observer, but the many structural complications due to an intricate network of minor faults, at least in North Dome and Middle Dome, are much less obvious. Though it is improbable that these faults have any relation to the occurrence of oil, an attempt was made to map them, not only to represent the structure adequately but also because the stratigraphy could not be understood if they were neglected. Faunal zones were particularly useful in mapping. On the other hand, some lithologic units proved to be more persistent than had been expected. The two sets of features-fossils and lithology-served as checks on each other.
