Report discussing the relationship between uranium deposits and hypogene mineral zoning in the Front Range mineral belt of Colorado. This report is mostly based on work done by other geologists.

From abstract: Many of the mining districts of the Colorado Front Range mineral belt contain mesothermal sulfide ores that exhibit a zonal distribution. Present data indicate that in most of the zoned districts pitchblende and/or secondary uranium minerals are most abundant in a transition zone between central areas containing predominantly pyritic gold ores and peripheral areas containing dominantly lead-zinc-silver deposits. Copper in the form of chalcopyrite is also probably more abundant in the transition zone than in adjacent zones.

From introduction: This report details the investigations of the physical stratigraphy of the Phosphoria Formation in northwestern Wyoming.

The following report presents the results of part of a geologic study of the phosphate deposits in central Florida. The purpose of the investigative research done in Florida is to determine the geologic history of the phosphate deposits and associated sediments, in order that the distribution of phosphate and uranium will be more clearly understood.

Discussing the stratigraphy of middle tertiary rocks in parts of West-Central Florida

From abstract: This report provides "hydrologic information for the north-central and western coal-mining regions of Missouri . . . to define the hydrologic system in these areas of major historic and planned coal development." It "describes the physical setting, climate, coal-mining practices, general hydrologic systems, and the current (1980) hydrologic data base in these two coal-mining regions."

From introduction: This study was begun in 1967 in cooperation with the Wisconsin Department of natural Resources (DNR)--its purpose was to evaluate the effects of construction of a reservoir and a floodwater-retention structure on the hydrologic system and water quality in a small basin in southwestern Wisconsin. In 1968, Federal research funds were obtained to provide for more detailed study of water quality and to extend the scope of the study to include aquatic biota.

A report regarding uranium resources of the Green River and Henry Mountains Districts, Utah. This report concerns work done on behalf of the division of Raw Materials of the U.S. Atomic Energy Commission.

From introduction: This report contains a general description of the hydrology of the project site, summaries of the data collected during 1971 to 1978, and discusses some of the factors affecting the hydrology of the site. This information and the water-level contour map (Fuentes and Patterson, 1979) will be helpful in designing an effective ground-water monitoring program and will provide baseline hydrologic information from which future changes can be detected.

The model discussed in this report simulates recharge to, flow through, and discharge from the water-table aquifer representative of most of Chester County, Pennsylvania. It includes maps and graphs.

A report which presents the results of a study of the uranium resources of the Green River and Henry Mountains districts, Utah, and is part of a series of similiar reports synthesizing the geologic relations of uranium deposits in all formations on the Colorado Plateau.

A report pertaining to uranium which has been found in two stratigraphic zones in rocks of permian age in northern Texas and south-central Oklahoma.

From abstract: A preliminary quasi-three-dimensional finite-difference ground-water-flow model of the seven-county Twin Cities Metropolitan area was constructed and used to evaluate parameter sensitivity and adequacy of available data.

Report discussing a geological study of the Chattanooga Shale of the Eastern Highland Rim area of Tennessee in 1947, 1948, and 1949 to determine its availability as a source of uranium.

Report discussing the progress made on a continuing geophysical program during the period from January to April, 1959. The purpose of the program was to determine the type and configuration of various rock units below the surface in areas of interest at the Nevada Test Site.

"This Progress report describes a part of a continuing geophysical program being conducted by the U.S. Geological Survey on behalf of the Albuquerque Operations Office, U.S. Atomic Energy Commission"

A report regarding reconnaissance for Uranium in Northern Texas and Southern Oklahoma. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

From purpose and scope: The purpose of this study was to update hydrologic data and refine understanding of the hydrologic system within the San Dieguito, San Elijo, and San Pasqual hydrologic subareas in San Diego County, Calif., and to evaluate the suitability of these areas for reclaimed water use.
