Tectonic map of Liberia based on geophysical and geological surveys
John Charles Behrendt, Cletus S. Wotorson
1972, Open-File Report 72-32
Interpretation of the results of aeromagnetic, total-gamma radioactivity, and gravity surveys combined with geologic data for Western Liberia from White and Leo (1969) and other geologic information allows the construction of a tectonic map of Liberia. The map approximately delineates the boundaries between the Liberian (ca. 2700 m.y.) province in...
Geological and geophysical investigations of an Apollo 9 photo anomaly near Point of Pines, Arizona
Calvin S. Bromfield, G. P. Eaton, D. L. Peterson, J.C. Ratte
1972, Open-File Report 72-51
An infrared photograph of southeastern Arizona, taken during the Apollo 9 multispectral terrain photography experiment in 1969, reveals a ringlike feature, some 3-4 miles (5-6 kin) in diameter, on the Natanes Plateau, 35 miles (56 kin) north of the town of Safford. Because the feature occurs in an area of...
Computation of fluvial-sediment discharge
George Porterfield
1972, Techniques of Water-Resources Investigations 03-C3
This report is one of a series concerning the concepts, measurement, laboratory procedures, and computation of fluvial-sediment discharge. Material in this report includes procedures and forms used to compile and evaluate particle-size and concentration data, to compute fluvial-sediment discharge, and to prepare sediment records for publication....
Low-flow investigations
H. C. Riggs
1972, Techniques of Water-Resources Investigations 04-B1
This manual describes methods of defining the low-flow characteristics of streams, shows how certain basin characteristics influence the mean and variability of annual low flows, and recommends procedures for data collection, analysis, and reporting....
Appraisal of stream sedimentation in the Susquehanna River basin
Kenneth F. Williams, Lloyd A. Reed
1972, Water Supply Paper 1532-F
The Susquehanna River presently transports about 3.0 million tons of sediment annually (110 tons per square mile). Only about 1.8 million tons of sediment enters the head of Chesapeake Bay annually because some sediment is trapped behind the power dams on the lower Susquehanna. Measured annual sediment yields from subbasins...
Energy resources of the United States
P. K. Theobald, Stanley P. Schweinfurth, Donald Cave Duncan
1972, Circular 650
Estimates are made of United States resources of coal, petroleum liquids, natural gas, uranium, geothermal energy, and oil from oil shale. The estimates, compiled by specialists of the U.S. Geological Survey, are generally made on geologic projections of favorable rocks and on anticipated frequency of the energy resource in the...
Estimated use of water in the United States in 1970
Charles Richard Murray, E. Bodette Reeves
1972, Circular 676
Estimates of water use in the United States in 1970 indicate that an average of about 370 bgd (billion gallons per day)about 1,800 gallons per capita per day--was withdrawn for the four principal off-channel uses which are (1) public-supply (for domestic, commercial, and industrial uses), (2) rural (domestic and livestock),...
Documentation and environment of the Apollo 16 samples a preliminary report
Water Resources Division, U.S. Geological Survey
1972, Open-File Report 72-395
This catalog is a working document that shows the locations from which samples were collected during the Apollo 16 mission, and that provides a descriptive geologic context for each sample. It is a compilation of notes from work in progress, and supersedes an earlier report prepared by the Apollo Lunar...
Ground motion values for use in the seismic design of the Trans-Alaska Pipeline system
Robert A. Page, D.M. Boore, W. B. Joyner, H.W. Coulter
1972, Circular 672
The proposed trans-Alaska oil pipeline, which would traverse the state north to south from Prudhoe Bay on the Arctic coast to Valdez on Prince William Sound, will be subject to serious earthquake hazards over much of its length. To be acceptable from an environmental standpoint, the pipeline system is to...
