Mineral occurrences (other than mineral fuels and construction materials) in the Bethel, Goodnews and Russian Mission quadrangles, Alaska
Joseph McCormick Hoare, Edward Huntington Cobb
1977, Open-File Report 77-156
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Bethel, Goodnews, and Russian Mission quadrangles in southwestern Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau...
Geochemistry and mineralogy of the carbonates of the Creede mining district, Colorado
Pamela Heald Wetlaufer
1977, Open-File Report 77-706
This paper describes the results of a study of the carbonate gangue in the silver-base metal ore deposit of the Creede mining district, located in Tertiary volcanic rocks of the central San Juan Mountains, southwestern Colorado. Two carbonate stages can be distinguished and defined on the basis of mineral association,...
Geohydrology of part of the Round Valley Indian Reservation, Mendocino County, California
K. S. Muir, Dwight Albert Webster
1977, Water-Resources Investigations Report 77-22
The Round Valley Indian Reservation in northern California obtains most of its water from the ground-water reservoir. The ground-water reservoir is made up of continental deposits, alluvium, and stream-channel deposits ranging in age from Pliocene to Holocene. Most of the water is pumped from the alluvium. Most ground water (about...
Nitrogen in water in Nassau and Suffolk counties, Long Island, New York, in 1971
Brian G. Katz, Stephen E. Ragone, C. Albert Harr
1977, Open-File Report 77-433
The concentration of inorganic nitrogen was measured in samples from 521 wells in the upper glacial and Magothy aquifers and from 46 streams in Nassau and Suffolk Counties during May 1971. The predominant form of dissolved nitrogen was nitrate. Nitrate concentrations (as N) in the upper glacial aquifer in both...
Low-flow characteristics of streams on the Olympic Peninsula, Washington
W.L. Haushild, D.E. LaFrance
1977, Open-File Report 77-812
Streams in lowland basins of the Olympic Peninsula, Washington, generally have their low flows in summer and peak flows in winter, whereas streams originating at higher elevations in the mountains have their low flows in late summer-early fall and they have both winter and spring peak flows. Data from long-term...
Correlation of major eastern earthquake centers with mafic/ultramafic basement masses
Martin Francis Kane
1977, Open-File Report 77-134
Extensive gravity highs and associated magnetic anomalies are present in or near seven major eastern North American earthquake areas as defined by Hadley and Devine (1974). The seven include the five largest of the eastern North American earthquake .centers. The immediate localities of the gravity anomalies are, however, relatively free...
Geology of the Monterey Bay region
H. Gary Greene
1977, Open-File Report 77-718
Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history. Uplift and depression have produced a succession of regressive and transgressive sedimentary units, while contemporaneous...
Digital model of the Arikaree Aquifer near Wheatland, southeastern Wyoming
Dwight T. Hoxie
1977, Open-File Report 77-676
A digital model that mathematically simulates the flow of ground water, approximating the flow system as two-dimensional, has been applied to predict the long-term effects of irrigation and proposed industrial pumping from the unconfined Arikaree aquifer in a 400 square-mile area in southeastern Wyoming. Three cases that represent projected maximum,...
The Eutaw-McShan aquifer in Mississippi
E. H. Boswell
1977, Water-Resources Investigations Report 76-134
This report, the fifth in a series of 'atlas-type' reports, summarizes the large amount of unpublished data available for the Eutlaw-McShan aquifer in Mississippi. The Eutaw-McShan aquifer, of Cretaceous age, consists of the interconnected irregular sand beds in the Eutaw and McShan Formations. The aquifer contains fresh water in an...
Limnological studies of the major streams in Chester County, Pennsylvania
Bruce W. Lium
1977, Open-File Report 77-462
The major streams in Chester County, Pennsylvania were studied to determine their environmental state, and to relate this condition to land- use patterns. A biological numerical rating system on a scale of 1 to 10 was developed to classify stream conditions. One indicates extremely toxic conditions and 10 balanced biological...
Summary appraisals of the Nation's ground-water resources; Souris-Red-Rainy region
Harold O. Reeder
1977, Open-File Report 77-565
A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and...
Preliminary foraminiferal biostratigraphy and correlation of selected stratigraphic sections and wells in the Gulf of Alaska Tertiary province
Weldon W. Rau, George Plafker, Gary R. Winkler
1977, Open-File Report 77-747
As part of ongoing research by the U.S. Geological Survey on the geology and resource potential of the Gulf of Alaska Tertiary Province, a vast amount of data has been accumulated over the past 25 years on the lithology and paleontology of bedded rocks in the province. This report brings...
