Land-surface subsidence in the Houston-Galveston region, Texas
R.K. Gabrysch, C.W. Bonnet
1974, Open-File Report 74-123
The pumping of large amounts of ground water in the Houston-Galveston region, Texas, has resulted in water-level declines of as much as 200 feet (61 metres) in wells completed in the Chicot aquifer and as much as 325 feet (99 metres) in wells completed in the Evangeline aquifer during 1943-73....
Storage of low-level radioactive wastes in the ground; hydrogeologic and hydrochemical factors
Stavros Stefanu Papadopulos, Isaac Judah Winograd
1974, Open-File Report 74-344
The status of mathematical simulation techniques, as they apply to radioactive waste burial sites, is briefly reviewed, and hydrogeologic and hydrochemical data needs are listed in order of increasing difficulty and cost of acquisition. Predictive modeling, monitoring, and management of radionuclides dissolved and transported by ground water can best be...
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...
Water supply at Painted Canyon Overlook, Theodore Roosevelt National Memorial Park (South Unit), southwestern North Dakota
M.G. Croft
1974, Open-File Report 74-136
A 1,930-foot (588-metre) water-supply well was constructed at the Painted Canyon Overlook, Theodore Roosevelt National Memorial Park (South Unit), southwestern North Dakota. Aquifers underlying the site are in rocks of Late Cretaceous and Tertiary age. These rocks have an aggreqate thickness of about 2,000 feet (610 metres). The well screen...
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,...
Review of waterpower classifications and withdrawals, Pit River basin, California
Sterling R. Osborne
1974, Open-File Report 74-64
The purpose of this report is to evaluate the existing waterpower classifications of the Geological Survey in the Pit River basin relative to the most recent water resources information and planning. A detailed description of Geological Survey classifications is given on pages 40 and 41. In a following section each...
A tabulation of K-Ar, Rb-Sr and Pb-alpha ages obtained for materials within the United States (including Alaska and Hawaii) during the years 1956 through 1964
Richard F. Marvin
1974, Open-File Report 74-1068
This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States from 1956 through 1964. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-a ages, but is probably 98 percent complete. Many of the radiometric ages...
A tabulation of K-Ar, Rb-Sr and Pb-alpha ages obtained for materials within the United States (including Alaska and Hawaii) during the years 1969 through 1971
Richard F. Marvin
1974, Open-File Report 74-1070
This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States from 1969 through 1971. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-α ages but is probably 98% complete. Many of the radiometric ages published...
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...
Hard iron ore at the Cliffs Shaft Mines, Ishpeming, Michigan
Jacob Eugene Gair
1974, Open-File Report 74-227
At the Cliffs Shaft Mines, for many years the premiere hard iron ore mine of Michigan, bodies of ore typically are localized in the upper part of the Negaunee iron-formation, close beneath Goodrich Quartzite in the axial part of the Marquette synclinorium. Individual ore bodies may be as much as...
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....
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...
Posssible extension of mineral belts, northern part of Coeur d'Alene district, Idaho
Garland Bayard Gott, Joseph Moses Botbol
1974, Open-File Report 74-67
The ore deposits in the northern part of the Coeur d'Alene district are located within rocks of the Belt Supergroup that have been intruded by Cretaceous quartz monzonites. Lead-zinc-silver replacement veins constitute most of the deposits. The geometry of the district has been modified by post-ore faulting along the Osburn,...
