Ground Water Test Well A, Nevada Test Site, Nye County, Nevada: A Summary of Lithologic Data, Aquifer (open access)

Ground Water Test Well A, Nevada Test Site, Nye County, Nevada: A Summary of Lithologic Data, Aquifer

Abstract: "ground-water test well A was drilled to a depth of 1,870 feet with rotary and cable-tool equipment. Only alluvial materials were penetrated. These were saturated below 1,605 feet. Pumping and bailing tests indicate that the minimum transmissibility of the alluvium is about 800 gallons per day per foot. The specific capacity was 1.9 gallons per minute per foot of drawdown after 1 hours of pumping at rates of both 41 and 60 gallons per minute. A suite of geophysical logs, a summary of contract costs, and a detailed description of drilling equipment and casing record are presented."

Stratigraphy of Outcropping Permian Rocks in Parts of Northeastern Arizona and Adjacent Areas (open access)

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

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.

Manganese Deposits in the Drum Mountains, Juab and Millard Counties, Utah (open access)

Manganese Deposits in the Drum Mountains, Juab and Millard Counties, Utah

From abstract: The Drum Mountains are in west-central Utah 30 miles northwest of Delta, between the Sevier Desert on the east and Whirlwind Valley on the west. It is a typically barren desert range comprising a westward-tilted structural unit in which is exposed as much as 9,000 feet of quartzite (Cambrian and Precambrian?) and 3,000 feet of carbonate rocks of Cambrian age. These beds, which strike northward and dip west, are cut by myriad east- to northeast trending faults with displacements of a few feet to a few thousand feet. Quartz monzonite dikes, pebble dikes, and vein deposits are present locally along the faults. The Cambrian rocks are overlain unconformably by volcanic rocks of probable Tertiary age.

Geology and Mineral Deposits of the Carlile Quadrangle, Crook County, Wyoming

From introduction: Geologic mapping of the Carlile quadrangle, which includes one of several uranium-producing areas in northeastern Wyoming, was undertaken to provide a detailed geologic map that could be used as an aid to further exploration for uranium deposits; to study in detail the known uranium deposits to determine whether or not there are any relations among structure, stratigraphy, lithology, and uranium deposits; and to outline, insofar as possible, areas favorable for more detailed exploration for uranium.

Tertiary Geology and Oil-Shale Resources of the Piceance Creek Basin, Between the Colorado and White Rivers, Northwestern Colorado

From introduction: The greatest known potential oil resource in the world occurs in the oil shale of the Green River formation, and the richest and thickest deposits occur within the area of this report. The purpose of this investigation was to obtain data on the stratigraphic distribution and areal extent of the oil-shale beds and to estimate the potential oil resources in the area.

Geology of the Mount McKinley Quadrangle, Alaska

From abstract: The Mount McKinley quadrangle, in south-central Alaska, includes parts of the Alaska Range, the Tanana and Kuskokwim lowlands, and the Kuskokwim Mountains. Schists of Precambrian age crop out in the northern foothills of the Alaska Range. Sedimentary and volcanic rocks of Paleozoic and Mesozoic age are exposed in the Kuskokwim Mountains, where little is known of their distribution and character, and in the Alaska Range, where they occupy the axial part and northern limb of a great synclinorium. Granitic batholiths, largely of Mesozoic age, intrude the Paleozoic and Mesozoic rocks in the Alaska Range.

Geology of the Craig Quadrangle, Alaska (open access)

Geology of the Craig Quadrangle, Alaska

From abstract: The Craig quadrangle, in southeastern Alaska, lies entirely within the Tongass National Forest and includes a large part of Prince of Wales Island, the largest island of the Alexander Archipelago. Sedimentary, volcanic, and metamorphic rocks of Paleozoic and Mesozoic age are exposed as complexly folded and faulted sequences. Paleozoic rocks occupy a broad geanticlinal area comprising Prince of Wales Island and the islands to the west. Metamorphosed Mesozoic rocks form a geosynclinal area along and east of Clarence Strait. Granitic and dioritic stocks and masses, mainly of Mesozoic age, intrude the Paleozoic and Mesozoic rocks. Remnants of volcanic rocks of Tertiary age exist on Suemez Island, and scattered areas of Tertiary clastic rocks and volcanic rocks are exposed near Clarence Strait. Deposits of Quaternary age are mainly thin glacial deposits and narrow bands of stream alluvium.
