Biological and microbiological assessment of the upper Chattahoochee River basin, Georgia
Bruce W. Lium, J. K. Stamer, T. A. Ehlke, R.E. Faye, R.N. Cherry
1979, Circular 796
Biological and microbiological studies were conducted by the U.S. Geological Survey as a part of the Intensive River-Quality Assessment studies of the upper Chattahoochee River basin, Georgia. Phytoplankton concentrations in cells per milliliter (cells/mL) were generally higher downstream from Atlanta than upstream. The highest concentrations, mostly blue-green algae, occurred in...
Hydrologic data on channel adjustments, 1970 to 1975, on the Rio Grande downstream from Cochiti Dam, New Mexico before and after closure
Jack D. Dewey, F.E. Roybal, D.E. Funderburg
1979, Water-Resources Investigations Report 79-70
Cross-section channel profiles, sediment transport and hydrologic data have been observed (before and after closure of the dam) and computed for a series of investigations from 1970 to 1975 at 37 cross sections established along a 59 mile (95 kilometer) study reach from Cochiti Dam to Isleta Diversion Dam, N....
Interpretation of thermoluminescence patterns around a Wyoming roll-type uranium deposit
Charles S. Spirakis
1979, Open-File Report 79-774
Thermoluminescence from quartz and feldspar grains in samples collected from the vicinity of a Wyoming roll-type uranium deposit show an increase in the importance of high-temperature thermoluminescence relative to low-temperature thermoluminescence of samples which are believed to be former positions of the migrating mineralized front. This effect is believed to...
The Alaskan Mineral Resource Assessment Program: Guide to information contained in the folio of geologic and mineral resource maps of the Chandalar quadrangle, Alaska
H. N. Reiser, W. P. Brosge, J. H. DeYoung, S.P. Marsh, T. D. Hamilton, J. W. Cady, N. R. D. Albert
1979, Circular 758
The Chandalar quadrangle in east-central Alaska was investigated by a multidisciplinary research group to assess the mineral resource potential of the quadrangle. This circular serves as a guide to and integrates with a folio of 10 miscellaneous field study (MF) maps and 2 open-file (OF) reports (table 1) concerned with...
The corrosive well waters of Egypt's western desert
Frank Eldridge Clarke
1979, Water Supply Paper 1757-O
The discovery that ground waters of Egypt's Western Desert are highly corrosive is lost in antiquity. Inhabitants of the oases have been aware of the troublesome property for many decades and early investigators mention it in their reports concerning the area. Introduction of modern well-drilling techniques and replacements of native...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Big Delta quadrangle, Alaska
Helen Laura Foster, N. R. D. Albert, Andrew Griscom, T. D. Hessin, W. D. Menzie, D. L. Turner, Frederic H. Wilson
1979, Circular 783
The geology, geochemistry, geophysics, and Landsat imagery of the Big Delta quadrangle, 16,335 km 2 in the Yukon-Tanana Upland of east-central Alaska, were investigated, and maps and reports were prepared by an interdisciplinary research team for the purpose of assessing the mineral potential. The quadrangle is dominantly a complex terrane...
Selected streamflow data for the Delaware River basin
Robert D. Schopp, Brian D. Gillespie
1979, Open-File Report 79-347
Selected streamflow data for the Delaware River basin are given in this report. Runoff-precipitation data covering the period 1941-70 are compiled for 28 selected subbasins. Low-flow frequency curves for four main-stem Delaware River sites are also given. For Delaware River at Montague and Trenton, New Jersey, monthly comparative duration curves...
Fluid inclusions in salt from the Rayburn and Vacherie domes, Louisiana
Edwin Roedder, H. E. Belkin
1979, Open-File Report 79-1675
Core samples from the Rayburn and Vacherie salt domes in Louisiana were examined for fluid inclusions, in connection with the possible use of such domes for nuclear waste storage sites. Three types of fluid inclusions were found, brine, compressed gas, and oil (in decreasing volume percent abundance). The total amount...
Mineral resources of the Big Frog Wilderness Study Area, Polk County, Tennessee and Fannin County, Georgia
John F. Slack, Gertrude C. Gazdik, Maynard L. Dunn
1979, Open-File Report 79-1209
The proposed Big Frog Wilderness is comprised of approximately 1820 hectares (18.2 km2) of mountainous terrain in the Cherokee and Chattahoochee National Forests south of the Ocoee River in Polk County, Tennessee, and Fannin County, Georgia. Rocks of the study area are greenschist-facies metasandstone, meta-arkose, metagraywacke, and dark slate of...
Petrology and stratigraphy of Paleogene nonmarine sandstones, Cascade Range, Washington
Virgil A. Frizzell
1979, Open-File Report 79-1149
The Cascade Range of Washington north of 47? latitude is composed of probable Paleozoic and Mesozoic metamorphic rocks and Mesozoic and Tertiary plutonic rocks. Several Paleogene nonmarine arkosic sandstone units fringe and in part occur within the complex crystalline core. The early to middle Eocene Chuckanut Formation is present on...
