A report regarding chemical composition as a guide to the size of uranium deposits in the Salt Wash member of the Morrison formation, Colorado Plateau

Abstract: "Thickness, grade, and depth data were obtained by analyzing gamma-ray logs and core samples from 56 diamond drill holes penetrating uranium deposits in the Colorado Plateau. The data from the two methods were compared to determine variations found in gamma-ray log interpretation and chemical and radiometric analyses of the drill core. Correlations within each parameter varied among the drilling areas analyzed. Gamma-ray interpretations of grade compared to chemical analyses were within the range of -10 to +25 percent. Most depth measurements determined by gamma-ray log interpretation compared to drill core measurement were within 0.5 percent. Results of the study indicate a need for better thickness definition in both gamma-ray logging and core scanning equipment."

From introduction: This report details the harbor site selection along the Gulf of Alaska for a nuclear detonation.

From introduction: This report is a summary of the detailed geologic and engineering information that is available on three sites for underground explosions on the Nevada Test Site.

A report about analyzing the age of igneous rock using its lead-alpha activity.

The following is a semiannual progress report, preliminary in nature, covering work done in the period of December 1, 1958 to May 31, 1959.

Photogeologic map marking topographic and geologic features of the Nash Quadrangle in Eddy County, New Mexico. Scale 1:24,000.

From introduction: Approximately fifty radioactive deposits and nearly fifty properties not abnormally radioactive were examined during a geologic reconnaissance for radioactive minerals in Idaho, Washington, and western Montana during the period July 1952 -- June 1955. The most important uranium deposits are in or near granitic to quartz monzonitic intrusions of probable Cretaceous age in central and northern Idaho, westernmost Montana, and northeastern Washington. The purpose of these reports is to describe the geology of the areas so that the possibilities for the disposal of high-level radioactive fluid waste in deep wells can be ascertained.

From introduction: This report includes a brief description of the stratigraphy and structure, and data on petrology, mineralogy, and chemical and physical properties of the rocks that are exposed in the U12b.01 tunnel of the U12b (Rainier) tunnel system.

A report regarding geological survey investigations in the U12b.03 and U12b.04 Tunnels, located at a Nevada test site.

From introduction: The papers comprising the various parts of this report contain the preliminary results of the U. S. Geological Survey investigations in the Ul2e.05 tunnel at the Atomic Energy Commission's Nevada Test Site, Nye County, Nevada (fig. 1). Reports on electrical resistivity, natural radioactivity, and heat required to raise the rocks to 100C will be issued later. A preliminary report on the geologic effects of the Blanca event is being prepared.

From abstract: The Homer district of the Kenai coal field is about 100 miles southwest of Anchorage, in south-central Alaska. It covers an area of about 1,100 square miles on the west side of the Kenai Peninsula, between Tustumena Lake and Kachemak Bay. The principal settlement is Homer, at the southern end of the district, which is connected by the gravel-surfaced Sterling Highway with the Alaska highway system and The Alaska Railroad, and is also served by ocean transportation and one airline.

From introduction: This report is based on preliminary surface mapping in the summer of 1952 and on subsurface exploration with a bulldozer powerauger unit in the summers of 1953 and 1954. In 1952 F. F. Barnes was assisted by Alfred Oestreich, geologist, and Lewis Ladwig and Richard Pack, field assistants. From July 2 to August 31, 1953, F. F. Barnes and Daniel Sokol were assisted by W.T. Ashlock and R. E. Rowland, field assistants, and by a bulldozer operator-mechanic. From June 23 to July 27, 1954, Barnes and Sokol were assisted by A. E. Burford and W. S. Hopkins, geologists, and an operator-mechanic.

From abstract: A gold-bearing area of about 7% square miles near the head of Glacier Bay between Reid and Lamplugh Glaciers was first discovered by Mr. Joseph Ibach in 1924. The dominant rock type in the area is granodiorite, which is intruded into bedded rocks that may be of Paleozoic age. The bedded rocks consist of conglomerate, limestone, and black graphitic schist. A light-colored quartz diorite younger than the granodiorite crops out south of the mapped area.

From introduction: The area of this report is in the northern part of southeastern Alaska (fig. 39). It includes about 400 square miles on northwestern Chichagof Island, latitude 5747' to 58*15' N. and longitude 135 57' to 136 35' W. It is covered by U. S. Geological Survey Mount Fairweather A-1, A-2, and Sitka D--7 and D-8 topographic quadrangle maps. The writer's geologic investigation was started in 1946 as a continuation of earlier work on the west coast of Chichagof Island by J. C. Reed and R. R. Coats (1941) of the U. S. Geological Survey.

Report discussing the geology and pegmatites of the Fourmile Quadrangle, located on the southwest side of the Black Hills uplift in Custer County, South Dakota. "This report is an abstract of a paper with the same title that is planned for publication as a Geological Survey professional paper."

A report about the Lemhi Pass area in the Beaverhead Mountains, Lemhi County, Idaho, and Beaverhead County, Montana, which was undertaken to determine the area as a potential source of thorium.

From introduction: This report is a summary of geologic information obtained by the USGS at Dolomite Hill, Nevada.

From abstract: The Geikie Inlet area is in the Glacier Bay region of southeastern Alaska, about 100 miles northwest of the city of Juneau. The area is mountainous with relief of slightly more than 5,000 feet, and the coastline is deeply indented by fiords and inlets. Most of the western half of the area is covered by glaciers.
