Water resources data for California, 1970; Part 2: Water quality reports
Water Resources Division, U.S. Geological Survey
1971, Water Data Report CA-70-2
Water-resources investigations of the U.S. Geological Survey include the collection of water-quality data on the chemical and physical characteristics of surface- and ground-water supplies of the Nation. These data for the 1970 water year for the quality of surface water in California are presented in this report. Data for a...
Water resources data for California, 1970; Part 1: Surface water records; Volume 2: Northern Great Basin and Central Valley
Water Resources Division, U.S. Geological Survey
1971, Water Data Report CA-70-1-2
Surface water records for the 1970 water year for California, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, are given in this report. Records for a few pertinent gaging stations in bordering States also are included. The records were collected and computed by...
Water resources data for California, 1970; Part 1: Surface water reports; Volume 1: Colorado River Basin, Southern Great Basin, and Pacific Slope Basins excluding Central Valley
Water Resources Division, U.S. Geological Survey
1971, Water Data Report CA-70-1-1
Surface water records for the 1970 water year for California, including records of streamflow or reservoir storage at gaging stations, partial record stations, and miscellaneous sites, are given in this report. Records for a few pertinent gaging stations in bordering States also are included. The records were collected and computed...
Hydrogeologic data for the Upper Connecticut River Basin, Connecticut
Robert B. Ryder, L.A. Weiss
1971, Connecticut Water Resources Bulletin 25
This report contains geologic, ground-water, and quality-of-water data collected and compiled for a water resources investigation of the upper Connecticut River basin, Connecticut by the U.S. Geological Survey in financial cooperation with the Connecticut Department of Environmental Protection. These data, together with surface-water data, were collected at sites shown on...
Program design for San Francisco Bay Region environment and resources planning study
Water Resources Division, U.S. Geological Survey
1971, Open-File Report 1640
The "Program Design" for the San Francisco Bay Region Environment and Resources Planning Study represents a refinement, elaboration, and extension of the plans which formed the basis for the cooperative program between the Department of the Interior, Geological Survey, and the Department of Housing and Urban Development, Office of Research...
Water table in Long Island, New York, March 1971
Edward J. Koszalka, Ellis Koch
1971, Report
The geologic framework and the hydrologic situation in Long Island are periodically reviewed by the U.S. Geological Survey as new knowledge is obtained from current investigations. This work is done through cooperative programs with Nassau and Suffolk County agencies and the New York State Department of Environmental Conservation. A unique...
An estimate of the juvenile sulfur content of basalt
J.G. Moore, Brent P. Fabbi
1971, Contributions to Mineralogy and Petrology (33) 118-127
Sulfur analyses by X-ray fluorescence give an average content of 107 ppm for 9 samples of fresh subaerially-erupted oceanic basalt and 680 ppm for 38 samples of submarine erupted basalt. This difference is the result of retention of sulfur in basalt quenched on the sea floor and loss of sulfur...
Reduction of lithologic-log data to numbers for use in the digital computer
C.O. Morgan, J.M. McNellis
1971, Journal of the International Association for Mathematical Geology (3) 79-86
The development of a standardized system for conveniently coding lithologic-log data for use in the digital computer has long been needed. The technique suggested involves a reduction of the original written alphanumeric log to a numeric log by use of computer programs. This numeric log can...
Distribution of elements in biotite-hornblende pairs and in an orthopyroxene-clinopyroxene pair from zoned plutons, northern Sierra Nevada, California
A. Hietanen
1971, Contributions to Mineralogy and Petrology (30) 161-176
Distribution of major and minor elements has been determined for five hornblende-biotite pairs from hornblende-biotite quartz diorite and monzotonalite and for a clinopyroxene-orthopyroxene pair from pyroxene diorite collected from the border zones and centers of zoned plutons in the northern Sierra Nevada, California. The distribution coefficients K d [Mg/Fe] for biotite/hornblende are of...
Primary distribution of silver and copper in native gold from six deposits in the Western United States
G. A. Desborough, Robert H. Heidel, W. H. Raymond, J. Tripp
1971, Mineralium Deposita (6) 321-334
Electron-microprobe analyses and mineragraphic studies of native gold demonstrate considerable variations in the primary intergrain and intragrain distribution of silver. The gold grains have from 1–55 weight percent silver; copper is present in grains from only one locality and ranges from 0.1–0.6 weight percent. Some gold...
Nesting by a yearling Canada goose
L. C. Hall, Frank B. McGilvrey
1971, Journal of Wildlife Management (35) 835-836
A free-flying Canada goose (Branta canadensis interior), known to be just under a year old, laid a clutch of four eggs at the Patuxent Wildlife Research Center. At least half of the 2-year-old females nest at Patuxent, and almost all of the 3-year-olds nest. As far as we know, this...
