Geologic map of the Monrovia Quadrangle, Liberia
Charles H. Thorman
1974, Open-File Report 74-305
As part of a program undertaken cooperatively by the Liberian Geological Survey and the U. S. Geological Survey, under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period 1965 to...
Simulated effects of oil-shale development on the hydrology of Piceance basin, Colorado
John B. Weeks, George H. Leavesley, Frank A. Welder, George J. Saulnier Jr.
1974, Open-File Report 74-255
The Piceance and Yellow Creeks drainage area is about 900 square miles (2,330 square kilometres) and is referred to as the Piceance basin, or simply as the basin. The surface-water and ground-water systems in the Piceance basin are intimately related. The annual volume of runoff from the basin (Piceance and...
Geology of quadrangles H-12, H-13, and parts of I-12 and I-13, (zone III) in northeastern Santander Department, Colombia
Dwight Edward Ward, Richard Goldsmith, Jaime B. Cruz, Hernan A. Restrepo
1974, Open-File Report 74-258
A program of geologic mapping and mineral investigation in Colombia was undertaken cooperatively by the Colombian Instituto Nacional de Investigaciones Geologico-Mineras (formerly known as the Inventario Minero Nacional), and the U. S. Geological Survey; by the Government of Colombia and the Agency for International Development, U. S. Department of State....
An assessment of areal and temporal variations in streamflow quality using selected data from the National Stream Quality Accounting Network
Timothy Doak Steele, Edward J. Gilroy, Richard O. Hawkinson
1974, Open-File Report 74-217
Streamflow chemical-quality data and stream-temperature data at 88 stations throughout the United States and Puerto Rico were analyzed to develop and to evaluate methodologies for the general assessment of the variation of the Nation's streamflow-quality conditions in space and over time. The spatial variation is described by the use of...
Geology of the Bopolu Quadrangle, Liberia
Roberts Manning Wallace
1974, Open-File Report 74-302
As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period...
Development and evaluation of a prototype global volcanic surveillance system utilizing the ERTS-1 satellite data collection system
Peter L. Ward, Elliot T. Endo, David H. Harlow, Rex Allen, Dan Marquez, Jerry P. Eaton
1974, Open-File Report 74-124
The ERTS Data Collection System makes it feasible for the first time to monitor the level of activity at widely separated volcanoes and to relay these data rapidly to one central office for analysis. This capability opens a new era in volcanology where the hundreds of normally quiescent but potentially...
Recommendations for the study and appraisal of oil-shale deposits in Jordan
Vernon Emanuel Swanson
1974, Open-File Report 74-197
A geologic-geochemical evaluation conducted October 5-24, 1968, both in the field area and in the laboratories has shown the Upper Cretaceous oil shale in the El Lajjun area of central Jordan to be one of Jordan's major natural mineral resources. Continued but slightly modified investigations are strongly recommended to determine...
Geothermal investigations in Idaho, Part 2, An evaluation of thermal water in the Bruneau-Grand View area, southwest Idaho, with a section on a reconnaissance audio-magnetotelluric survey
H.W. Young, R.L. Whitehead, Donald B. Hoover, C. L. Tippens
1974, Open-File Report 74-221
The Bruneau-Grand View area occupies about 1,100 square miles in southwest Idaho and is on the southern flank of the large depression (possibly a graben) in which lies the western Snake River Plain. The igneous and sedimentary rocks in the area range in age from Late Cretaceous to Holocene. They...
Gravel resources, urbanization, and future land use, Front Range Urban Corridor, Colorado
James M. Soule, Harold R. Fitch
1974, Open-File Report 74-178
An assessment of gravel needs in Front Range Urban Corridor markets to 2000 A.D., based on forecast population increases and urbanization, indicates that adequate resources to meet anticipated needs are potentially available, if future land use does not preclude their extraction. Because of urban encroachment onto gravel-bearing lands, this basic...
Geology of the Juazohn Quadrangle, Liberia
Russell G. Tysdal
1974, Open-File Report 74-309
As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period...
Geological Survey published reports on Alaska, 1884-1914, indexed by quadrangle
Edward Huntington Cobb
1974, Open-File Report 74-345
Geological Survey reports published as Annual Reports, Monographs, Special Reports, Professional Papers, Bulletins, and Water Supply Papers are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). This index does not include any reports that deal solely with administrative matters.Reports that deal...
Geothermal gas sampling methods
Alfred Hemingway Truesdell, K.L. Pering
1974, Open-File Report 74-361
The following method of geothermal gas collection meets our needs for chemical and isotopic gas analyses, requires a minimum of special equipment in the field, and provides field analytical data of assistance in a sampling program....
