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....
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...
Volcanic hazards on the Island of Hawaii
Donal Ray Mullineaux, Donald W. Peterson
1974, Open-File Report 74-239
Volcanic hazards on the Island of Hawaii have been determined to be chiefly products of eruptions: lava flows, falling fragments, gases, and particle-and-gas clouds. Falling fragments and particle-and-gas clouds can be substantial hazards to life, but they are relatively rare. Lava flows are the chief hazard to property; they are...
Atlantic OCS resource and leasing potential
Richard Q. Foote, Robert E. Mattick, John Charles Behrendt
1974, Open-File Report 74-348
Thick marine sedimentary sections and geologic structures favorable for the accumulation of petroleum are indicated in Georges Bank basin, the Baltimore Canyon trough, and the Southeast Georgia embayment. Undiscovered recoverable resources of petroleum on the Atlantic OCS are estimated to be 10 billion to 20 billion barrels of oil and...
South Carolina seismic program
Arthur C. Tarr, Kenneth W. King
1974, Open-File Report 74-58
The principal objectives of the South Carolina Seismic Program are to: (1) provide essential high-quality raw seismic data for earthquakes in South Carolina; (2) compute accurate estimates of event and source parameters; (3) provide a catalog of events and source parameters that will be used in further evaluation of seismic...
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...
Antimony and other metal anomalies south of Stibnite, Valley County, Idaho
Gary C. Curtin, Harley D. King, B.F. Leonard
1974, Open-File Report 74-111
Results of geochemical investigations south of Stibnite, Valley County, Idaho, show that the distribution of Sb, As, Au, Zn, Ag, and Mo in mull ash and of Hg, in soil forms a highly anomalous area which is more than 1.5 km long and 1 km wide along the trace of...
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...
