Anomalous concentrations of gold, silver, and other metals in the Mill Canyon area, Cortez quadrangle, Eureka and Lander Counties, Nevada
James E. Elliott, John David Wells
1968, Circular 606
The Mill Canyon area is in the eastern part of the Cortez window of the Roberts Mountains thrust belt in the Cortez quadrangle, north-central Nevada. Gold and silver ores have been mined from fissure veins in Jurassic quartz monzonite and in the bordering Wenban Limestone of Devonian age. Geochemical data...
A list of references on lead isotope geochemistry through 1966
Bruce R. Doe
1968, Open-File Report 68-76
This bibliography was constructed to be as complete as possible for terminal papetrs containing new data relative to the geochmical applications of Common lead U-Th-Pb isotopic dating Pb-α Pb210, Pb212, Pb214 No effort was made for completeness of: Annual report, Yearbooks, etc. Review papers although many are included. Abstract and these are omitted....
Fresh and saline ground-water zones in the Punjab region, West Pakistan
W.V. Swarzenski
1968, Water Supply Paper 1608-I
An extensive program of test drilling and water sampling, undertaken by the Water and Soils Investigation Division (WASID) of the West Pakistan Water and Power Development Authority (WAPDA) to evaluate hydrologic problems related to waterlogging and soil salinity, has furnished data for the delineation of fresh and saline ground-water zones...
Water data for metropolitan areas: A summary of data from 222 areas in the United States
1968, Water Supply Paper 1871
Expansion of metropolitan areas poses persistent problems in management of the hydrologic environment. Adequate hydrologic data are prerequisite to proper planning and engineering design of urban environments. Some such data are available and are tabulated for each Standard Metropolitan Statistical Area in the United States. Information for each area consists...
Analysis of water quality of the Mahoning River in Ohio
Gene A. Bednar, Charles R. Collier, William Perry Cross
1968, Water Supply Paper 1859-C
The Mahoning River drains the densely populated and industrialized Warren-Youngstown area in northeastern Ohio. Significant chemical constituents and physical properties generally regarded as important in establishing water-quality standards for the Mahoning River are evaluated on the basis of hydrologic conditions and water use. Most of the interpretations and the appraisal...
Ground-water exploration in the Bosque del Apache Grant, Socorro County, New Mexico
James B. Cooper
1968, Open-File Report 68-63
Test drilling along the Rio Grande in the Bosque del Apache Grant in Socorro County, New Mexico has shown that the area is hydrologically complex and that the quality of the ground water varies from saline to fresh within short distances both laterally and vertically. Nearly all of the riverside...
Progress report, 1966-1967: Water study - Greater Anchorage area, Alaska
William W. Barnwell, Raymond S. George
1968, Open-File Report 68-6
The purpose of the 5-year cooperative water resources study of the Greater Anchorage area by the Geological Survey is to appraise the water resources of the area and obtain data needed to solve water problems and to assist in the orderly development and management of the resource....
Water-discharge determinations for the tidal reach of the Willamette River from Ross Island Bridge to Mile 10.3, Portland, Oregon
G.R. Dempster, Gale A. Lutz
1968, Water Supply Paper 1586-H
Water-discharge, velocity, and slope variations for a 3.7-mile-Iong tidal reach of the Willamette River at Portland, Oreg., were defined from discharge measurements and river stage data collected between July 1962 and January 1965. Observed water discharge during tide-affected flows, during floods, and during backwater from the Columbia River and recorded...
Platinum deposits of Alaska
John Beaver Mertie Jr.
1968, Open-File Report 68-177
The placer deposits of the Goodnews Bay district in southwestern Alaska have yielded the only significant production of platinum metals in the United States, although small amounts of platinum metals have been produced from other deposits in Alaska and elsewhere in the United States. The Goodnews Bay deposits were described...
Water temperatures in the lower Columbia River
Albert M. Moore
1968, Circular 551
Daily observations of water temperature for 20 sites in the lower Columbia River are presented in tabular form and in profile form by months for the period August 1941 to July 1942. The profiles show minimum, mean (average), and maximum water temperatures for those months from river mile 142 to...
Storage requirements for Arkansas streams
James Lee Patterson
1968, Water Supply Paper 1859-G
The supply of good-quality surface water in Arkansas is abundant. owing to seasonal and annual variability of streamflow, however, storage must be provided to insure dependable year-round supplies in most of the State. Storage requirements for draft rates that are as much as 60 percent of the mean annual flow...
Hydrology of Crater, East and Davis Lakes, Oregon; with section on Chemistry of the Lakes
Kenneth N. Phillips, A. S. Van Denburgh
1968, Water Supply Paper 1859-E
Crater, East, and Davis Lakes are small bodies of fresh water that occupy topographically closed basins in Holocene volcanic terrane. Because the annual water supply exceeds annual evaporation, water must be lost by seepage from each lake. The seepage rates vary widely both in volume and in percentage of the...
Infrared survey of the Pisgah Crater area, San Bernardino County, California - a geologic interpretation
Stephen J. Gawarecki
1968, Open-File Report 69-104
The infrared survey of the Pisgah Crater Area, San Bernardino County, California was primarily undertaken to establish parameters by which rock types, structures, and textures peculiar to this locale could be recognized or differentiated. A secondary purpose was to provide an adequate evaluation and calibration of airborne and ground-based instruments...
A geophysical study in Grand Teton National Park and vicinity, Teton County, Wyoming
John Charles Behrendt, Benton L. Tibbetts, William E. Bonini, Peter M. Lavin, J. D. Love, John C. Reed
1968, Professional Paper 516-E
An integrated geophysical study - comprising gravity, seismic refraction, and aeromagnetic surveys - was made of a 4,600-km2 area in Grand Teton National Park and vicinity, Wyoming, for the purpose of obtaining a better understanding of the structural relationships in the region. The Teton range is largely comprised of Precambrian...
