Water-resources data, 1970-75, for Perris Valley and vicinity, Riverside County, California
David J. Lang
1979, Open-File Report 79-1256
In 1969 the U.S. Geological Survey began in Perris Valley, Calif., to determine changes in the hydrologic regime as a rural area becomes urbanized. The investigations spanned several years when precipitation was below normal in most of southern California. Surface-water records were collected for a 6-year period at 21 sites, and...
Hydrologic data for water-table aquifers in the greater Denver area, Front Range Urban Corridor, Colorado
Donald E. Hillier, Paul A. Schneider, E. Carter Hutchinson
1979, Open-File Report 79-214
As part of the U.S. Geological Survey 's investigations of the hydrology and geology in the Front Range Urban Corridor of Colorado, hydrologic data for water-table aquifers in the greater Denver area were collected and compiled during 1976-77. These data, consisting of records for 325 wells and 11 springs and...
Water-quality investigation of the Flat Bayou watershed, Jefferson County, Arkansas
T.E. Lamb
1979, Open-File Report 79-1300
The results of a 1-year study, in 1977-78, of surface-water quality in the Flat Bayou watershed, Jefferson County, Ark. are presented to document conditions before implementation of Soil Conservation Service programs. Analysis of samples collected at two sites showed that oxygen depletion, as low as 32 percent of saturation at...
Uranium and organic matters: use of pyrolysis-gas chromatography, carbon, hydrogen, and uranium contents to characterize the organic matter from sandstone-type deposits
Joel S. Leventhal
1979, Open-File Report 79-942
Organic matter seems to play an important role in the genesis of uranium deposits in sandstones in the western United States. Organic materials associated with ore from the Texas coastal plain, Tertiary basins of Wyoming, Grants mineral belt of New Mexico, and the Uravan mineral belt of Utah and Colorado...
Some peat deposits in Penobscot County, Maine
Cornelia Clermont Cameron, Walter A. Anderson
1979, Open-File Report 79-1096
Twenty of the peat deposits in Penobscot County, Maine contain an estimated 29,282,000 short tons air-dried peat. The peat is chiefly sphagnum moss and reed-sedge of high quality according to ASTM standards for agricultural and horticultural use. Analyses show that this same volume has high fuel value, low sulfur and...
Water-quality investigation of the Caney Creek watershed, northeast Arkansas
T.E. Lamb, G. Newsom
1979, Open-File Report 79-1064
The results of a 1-year study, in 1977-78, of surface-water quality in the Caney Creek watershed are presented to document conditions before implementation of Soil Conservation Service programs. Analyses of samples collected at two sites shows that water in Caney Creek and Caney Creek Ditch is of good quality with...
Key to the common marine molluscs of Texas
Gary W. Hill
1979, Open-File Report 79-969
A dichotomous key is developed which provides the investigator a means for identifying the common marine molluscs on the Texas coast. The key is written as to allow the user to stop or begin at any desired taxonomic level (class, order, superfamily, family, genus, species) depending on prior knowledge or...
Ground-water quality in selected areas of Wisconsin
S. M. Hindall
1979, Open-File Report 79-1594
Analysis of 2,071 ground-water samples from 970 wells throughout Wisconsin indicate large variations in ground-water quality. Ground water in Wisconsin is generally suitable for most uses, but in some areas concentrations of chemical constituents exceed recommended drinking-water standards. Iron, manganese, and nitrate commonly exceed recommended drinking-water standards and dissolved solids,...
Streamflow Estimates in Selected Wisconsin Streams
R.P. Novitzki
1979, Open-File Report 79-1282
The Wisconsin Department of natural Resources needs streamflow information in lake basins where lake-rehabilitation programs are implemented but where long-term stream-gaging stations are not justified. The U.S. Geological Survey provided streamflow estimates for 24 streams in Wisconsin. The estimates were made by the use of (1) midmonthly measurements, (2) basin...
HYPOELLIPSE: A computer program for determining local earthquake hypocentral parameters, magnitude, and first motion pattern
John C. Lahr
1979, Open-File Report 79-431
HYPOELLIPSE is a computer program for determining the hypocenters of local or near regional earthquakes and for each event the ellipsoid which encloses the one standard deviation region. Traveltimes are determined from a horizontally layered crustal structure or from a linear increase of velocity with depth. Arrival times for the...
Late diagenetic indicators of buried oil and gas: II, Direct detection experiment at Cement and Garza oil fields, Oklahoma and Texas, using enhanced LANDSAT I and II images
Terrence J. Donovan, Patricia A. Termain, Mitchell E. Henry
1979, Open-File Report 79-243
The Cement oil field, Oklahoma, was a test site for an experiment designed to evaluate LANDSAT's capability to detect an alteration zone in surface rocks caused by hydrocarbon microseepage. Loss of iron and impregnation of sandstone by carbonate cements and replacement of gypsum by calcite are the major alteration phenomena...
