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...

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....
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...
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...

Tin resources of Brazil
Max Gregg White
1974, Open-File Report 74-333
Annual tin production in Brazil, most of it from cassiterite placer deposits in Rondonia Territory, amounts to about 4,000 metric tons (4,400 short tons) of concentrate containing 66 percent tin, much of which is consumed by Brazilian industry. Reserves of cassiterite concentrate in the placers of Rondonia district are estimated at...
Tungsten resources of Brazil
Max Gregg White
1974, Open-File Report 74-332
Brazilian tungsten production, 85 percent of which is exported, comes almost entirely from scheelite-bearing tactites in northeast Brazil, and has reached an annual rate of about 2,000 metric tons (2,200 short tons) of scheelite concentrate with 70 percent WO3. Scheelite ore reserves, located principally in the State of Rio Grande...
Mineral resources of proposed additions to the Salmon-Trinity Alps Primitive Area, California
Preston E. Hotz, Robert C. Greene, Terry J. Close, Robert K. Evans
1974, Open-File Report 74-71
A mineral survey of four areas totalling 80 square miles, not included during the 1968-70 examination of the proposed Salmon-Trinity Alps Wilderness, was made by the U.S. Geological Survey and U.S. Bureau of Mines in 1973. Geological Survey personnel mapped the geology and collected stream-sediment and rock samples for spectrographic...

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...
Reconnaissance engineering geology of Sitka and vicinity, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Lynn A. Yehle
1974, Open-File Report 74-53
A program to study the engineering geology of most of the larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about Sitka and vicinity is a product of that program. Field-study methods were of a reconnaissance nature,...
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
