Mineral resources of the Charles Sheldon wilderness study area, Humboldt and Washoe Counties, Nevada, and Lake and Harney Counties, Oregon

A mineral survey of the Charles Sheldon wilderness study area, located in Humboldt and Washoe Counties, Nevada, and Lake and Harney Counties, Oregon was conducted in 1974 and 1975 (fig. 1A, 1B, 1C). The mineral resource potential was evaluated by geological, geochemical, and geophysical studies by the U.S. Geological Survey, and by the examination of mines, prospects, and other mineralized localities by the U.S. Bureau of Mines. The investigation identified several areas of significant mineral potential within the study area which includes the Charles Sheldon Antelope Range and the Sheldon National Antelope Refuge (fig. 1B). The Virgin Valley area contains reserves of precious opal, small quantities of decorative building stone, and low-grade uranium resources. The investigation indicates that there are several areas of potential for the discovery at depth of mercury and for base and complex precious metal sulfide deposits within the study area. Reservoir temperatures, estimated from the analysis of thermal springs, suggest that the area has low-to-moderate potential for geothermal resources. The potential for oil, gas, or coal is very low.

Coal resources of southeastern Massachusetts assessed in 1942

Large easily mined coal deposits of usable quality would be of great value to Massachusetts, particularly in war time. Every effort has been made in this study to evaluate the probable occurrence, quantity, and quality of the coal deposits in southeastern Massachusetts but unfortunately it is impossible from surface observations alone to ascertain adequately the coal resources of this area. Only by means of widespread and systematic underground exploration, accomplished best by core drilling, can the coal resources be determined. All the available data concerning the coal resources is analyzed in this report in order to indicate the feasibility of such an exploration program and where it is most likely to be successful.

Geology and industrial mineral resources of the Macon-Gordon kaolin district, Georgia

The Macon-Gordon kaolin district is about 80 miles (130 km) southeast of Atlanta, Georgia. It extends across the boundary between, and includes parts of, the Piedmont and Atlantic Coastal Plain physiographic provinces. The rocks in the Piedmont are mainly intensely folded sericite schist and granite gneiss containing irregular masses of amphibolite and feldspathic biotite gneiss and scattered igneous intrusive rocks. Most of the crystalline rocks are thought to be of Paleozoic age, but some of the intrusive rocks may be younger. The crystalline rocks are cut by a major unconformity and are overlain by sedimentary formations ranging in age from Cretaceous to Miocene. The valuable kaolin deposits occur in the Cretaceous beds, undivided, and in the Huber Formation which is of Paleocene to middle Eocene age. The resources of kaolin in the district are estimated in millions of metric tons as follows: reserves, 100; subeconomic resources, 700 to 900; undiscovered resources, probably 700 to 1,000. In addition to kaolin, the leading mineral commodity mined in the district, crushed stone and sand are now being produced, and fuller's earth and a minor amount of limestone were formerly produced. The crushed stone is quarried from igneous rocks in the Piedmont province. The sand is washed from the Cretaceous beds, undivided. The fuller's earth was mined from the Twiggs Clay Member of the Barnwell Formation, and limestone was dug from the Tivola Limestone.

Water-resources investigations of the U.S. Geological Survey, New Mexico District, fiscal year 1978

This is the first of an annual series of reports in which the program of the New Mexico District, U.S. Geological Survey, Water Resources Division, will be summarized. This report, which is for fiscal year 1978, should be useful to cooperating agencies and to the users of water data in that it summarizes and gives the status of the basic data collection program and all current studies of the Water Resources Division in New Mexico. The water-resource programs of the District are composed of surface water, ground water, and water quality disciplines. As of April 1978 the District had 36 active projects, 30 reports for release, and answered about 5,000 requests for water related information. (Woodard-USGS)

Resource report for proposed OCS lease sale 57: Norton Basin, Alaska

This report is a summary of information about an area of the northern Bering Sea continental shelf that is bounded by the Seward Peninsula on the north, by the line of the United States-Russia Convention of 1867 on the west, and by St. Lawrence Island and the coastline that rims Norton Sound on the south and east. Scholl and Hopkins (1969) report that a sedimentary basin underlies the offshore area. More recent data, which form the basis of part of this report, show the basin is deepest beneath Norton Sound; also, the basin has sufficient depth and areal extent that the basin may be a target for development of hydrocarbon resources after Outer Continental Shelf (OCS) Lease Sale 57. The informal, but widely used, name for the basin is Norton Basin. The following discussion includes regional geology, geologic history, and offshore structure and stratigraphy as background data to discussion of the hydrocarbon potential and resource appraisal of the offshore area. Sections on environmental geology and on the technology and manpower needed and available for development of offshore resources are also included.

Water-resources appraisal of the south-Arkansas lignite area

The feasibility of developing lignite resources in south-central Arkansas is an important question at the present time (1978). Part of the concern is related to the possible impacts that mining and processing of lignite will have on water resources. Not only will the disturbance caused by excavating affect the quantity and quality of surface and ground water but, the mining, processing, and conversion processes will require the use and consumption of significant quantities of water. In order to assess the magnitude of the effects of strip mining upon both surface and ground water, baseline conditions (hydrologic conditions in the area prior to mining) must be well defined. A thorough data file and literature search was made so that baseline conditions in the area could be defined. In addition, data-collection networks have been established for the collection of quantitative and qualitative information on streamflow and water levels in the aquifers. Data collected to date at these sites are included in the report. Collection of data at these sites will continue through at least September 1979. Information presented in this report can be used to estimate the quantities of water available for use and the possible effects of mining and associated dewatering on water resources.

Water-resources investigations of the U.S. Geological Survey in Arkansas, fiscal year 1981

During fiscal year 1981 there were 20 water-resources investigations in progress by the Arkansas District of the U. S. Geological Survey 's Water Resources Division. Investigations that mainly involved data collection included surface-water gaging, water-level measuring, water-quality sampling, sediment sampling, and water-use inventorying. Interpretive studies included three that were principally of ground-water resources, four that were of surface-water flow charateristics, four that were of surface-water quality characteristics, and three that were interdisciplinary.

U.S. Geological Survey reports on the water resources of Florida, 1886-1980

The U.S. Geological Survey has been making investigations of the water resources of Florida since the latter part of the 19th century. The earlier work consisted mainly of data collection at a few spring and river sites at intermittent intervals with the exception of a statewide ground-water study made during 1910-12 (Matson and Sanford, 1913). Since 1930, when an office was established for surface-water studies and in 1938 for ground-water studies in Florida, practically all of the water-resources investigations made by the U.S. Geological Survey have been in cooperation with state and local agencies. This second edition of "United States Geological Survey Reports on the Water Resources of Florida, 1886-1980" includes reports approved for release in calendar year 1980. In addition to updating the first edition (1980) several reports released prior to 1979, which were inadvertently omitted, have been added. The bibliographic list of publications which follows is arranged alphabetically by senior author. The publications are also indexed by geographic area and by subject. Only two lines are used for each publication in the indexes; thus the complete reference is given only in the bibliographic list.
