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...

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...
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...

Geology and mineralogy of phosphate rock in the Bambui group near Cedro do Abaete and vicinity, Minas Gerais, Brazil
James Bachelder Cathcart
1974, Open-File Report 74-219
Discontinuous lenticular masses of phosphate rock are present near or at the contact between the green mudstone and the underlying red and yellow clay-stone units of the Serra da Saudade Member of the Rio Paraopeba Formation of the Bambui Group of late Precambrian to early Paleozoic age. The lenses are...

Long term flow of the Truckee River in California and Nevada
Howard Frederick Matthai
1974, Open-File Report 74-213
The Office of the Solicitor, Department of the Interior, requested the Geological Survey to evaluate the reliability of streamflow records in the Truckee River basin and to determine the long-term average annual runoff.The reliability of streamflow records was evaluated by comparisons between pairs of records at six locations along the...

Characteristics of streamflow and ground-water conditions in the Boise River Valley, Idaho
C.A. Thomas, N. P. Dion
1974, Water-Resources Investigations Report 74-38
The quantity, quality, and distribution in time of streamflow in Boise River below Lucky Peak Lake are drastically affected by storage reservoirs, diversions for irrigation, and by domestic, industrial, and agricultural wastes. Reservoirs usually fill during the nonirrigation season, and streamflow for several miles below Lucky Peak Lake is very...
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...

An investigation of basin effects on flood discharges in North Dakota
Orlo A. Crosby
1974, Open-File Report 74-346
An investigation of the relationship of peak discharge to causative storm variables and drainage-basin characteristics was made to provide guidelines for future analyses of frequency and magnitudes of floods from small drainage areas. The procedure used was (l) to estimate peak discharges on the ll study basins from multiple-regression models developed from the storm variables and...
