From abstract: This report describes the Chariot test at Ogotoruk Creek that is topographically and geologically well-situated for the construction of an experimental deep-water excavation as proposed by the AEC.

From introduction: This report details the results of geologic investigations in support of Project Chariot.

The following report is the last in a series of periodic reports covering investigations made by the U.S. Geological Survey on behalf of the Divisions of Raw Materials and Research of the U.S. Atomic Energy Commission. The following is a bibliography of Geological Survey publications stemming from investigations on radioactive materials and deposits since 1942.

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."

From Introduction: "In the Uravan and Gateway districts, the general character of the bedding in the ore-bearing sandstone and amount of alteration in associated mudstones, and the relation of these to each other, are the features most useful as large-scale guides. This report describes these features and their distribution, as well as some other significant geologic characteristics of the ore-bearing sandstone."

A report discussing and area of 2.5 square miles along the southwest border of the pre-Cambrian granitic rocks complex in the pre-Cambrian core of the Harney Peak region, Black Hills, South Dakota that was mapped to determine the relationship between the granite-pegmatite complex and the pegmatites containing beryl and other industrial minerals. This investigation was part of the U.S. Geological Surveys program for the investigation of domestic beryllium resources and was carried out on behalf of the Atomic Energy Commission.

A report, with accompanying maps, showing distinguishable lithologic units and occurrences of uranium in outcrops in the Pumpkin Buttes area of the Powder River Basin

From introduction: Ground water is a source of municipal, domestic, stock, and irrigation water supply for most of northeastern Larimer County, Colorado. This report presents the results of a study made to determine the quantity, availability, and quality of the ground water. This information should be useful particularly for land-use planning and the utilization and protection of the ground-water resources.

From abstract: because of the increased demands for water in eastern Colorado, principally in the urbanizing Denver metropolitan area, increased diversions of water from Dillon Reservoir are planned. Estimates of end-of-month storage in Dillon Reservoir, assuming the reservoir was in place and 131,000 acre-feet of water were diverted from the reservoir each year, were reconstructed by mass balance for the 1931-77 water years. Based on the analysis, the annual maximum end-of-month drawdown below the elevation at full storage would have been 171 feet.

From abstract: "Various changes in the management practices for the Winnebago pool to protect wetlands adjacent to the pool and to assure adequate streamflow downstream from the pool have been proposed. The effects of three such changes were estimated by using a digital reservoir model to simulate daily stage and discharge."

The following report analyzes the contaminant materials found in glaciers and ice caps.

From abstract: The secondary uranium minerals metatorbernite (?) and autunite (?) were discovered at Indian Creek in the spring of 1950. The deposits, in sec. 28, T. 27 S., R. 6 W., Beaver County, Utah, are 20 miles west of Marysvale, and about three-eighths of a mile east of a quartz monzonite stock.

From introduction: This report details Vela Uniform program survey that determined the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel for comparison with similar post-shot geologic data and evaluated these data in terms of predicting the geologic effects of the planned explosion.

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

A report discussing two diamond-drill exploration projects in the Beaver Mesa Area

From abstract: The Geological Survey has completed a program of uranium investigation and geologic mapping in the Monument Valley area, Apache and Navajo Counties, Ariz. The program, undertaken on behalf of the 'Atomic Energy Commission, had two principal objectives. The first was to establish prospecting guides for uranium ore deposits. The second objective was to appraise the relative favorableness of formations and areas for the occurrence of uranium deposits in order to select localities that deserve further exploration.

This report presents the results of a study of leached-zone material in overburden dumps at international Minerals and Chemical Corporation's Peace valley mine and Swift and Company's Varn mine.

This report presents survey findings for the Green Swamp in Florida. It includes maps, graphs, and tables.

Summary: The Lost Creek schroeckingerite deposit in Sweetwater County, Wyo., has attracted attention in the past both as an occurrence of comparatively rare minerals and more recently as a possible source of uranium ore. During the summer of 1948 a newly-formed company by the name of Uranium, Inc., explored part of the deposit by bulldozer trenching and drilling. under the technical direction of the Minerals Engineering Company of Grand Junction, Colo. Examination of the significant exposures of the schroeckingerite deposit indicated that the uraniferous beds are discontinuous and that their areal distribution is erratic. The overburden has an average thickness of 2.5 feet.

From introduction: The results presented in this preliminary report are principally concerned with the ground motion caused by seven underground nuclear explosions (table 1) in the bedded tuff of the Oak Spring formation in Area 12. Ground motions were recorded at stations as close as 5 kilometers and as far as 300 kilometers from the explosions (fig 1 and table 2). The results for the Bianca and especially the Evans explosion are meager because the first was accompanied by a Test Site-wide moznentary power failure and because the yield of the second was so far below the anticipated yield that uncertain results were obtained. Ground motions caused by most of the air explosions in Operations Plumbbob and Hadtack - Phase 2 were recorded and have been partly analyzed. Results are presented in this report only where they relate significantly to analysis of the underground explosions. The effects of most of the small underground explosions in Area 3 (center of Yucca Flat) that had significant yields were also recorded. The results have not yet been interpreted.

From introduction: This report presents practical and useful sediment-yield information for Wisconsin. Measured and estimated sediment yields are supplemented by information on suspended-sediment concentration and particle size of suspended and bed material for 84 sites in the State. To expand the usefulness of these data, an additional section in the report presents a method to estimate or predict sediment yields in ungaged streams.

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 abstract: "This report is a survey of present and potential production of monazite from part of the Maryland-Florida section of the Atlantic Coastal Plain."

Abstract: Chemical and microbiological data from four characteristically acidic streams in southern New Jersey were used to evaluate seven factors related to the proclivity of each stream to nitrify under the influence of secondary sewage effluent. pH, water temperature, and dissolved oxygen were used as indicators of a stream conditions while neutralization of alkalinity, nitrogen species trends, BOD/NOD incubations, and nitrifying bacteria densities served as actual nitrification indicators. Hay Stack Brook showed strong evidence for nitrification on the basis of all four nitrification indicators while Landing Creek was nitrifying little if at all. Hammonton Creek is apparently nitrifying, but because of uncertainty in the downstream trends of the nitrogen species, and a lower level of alkalinity neutralization, it is nitrifying less than Hay Stack Brook. Squankum Branch showed some evidence for nitrification on the basis of the BOD/NOD incubations. The acidic character of these streams does not appear to be an exclusive factor in determining whether the stream will undergo nitrification.
