Plan of study of the hydrology of the Madison Limestone and associated rocks in Montana, Nebraska, North Dakota, South Dakota, and Wyoming
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-631
A major part of the United States ' coal reserves is in the Fort Union coal region of the Northern Great Plains. Large-scale development of these reserves would place a heavy demand on the area 's limited water resources. Surface water is poorly distributed in time and space. Its use...
Depositional environments and paleocurrent directions in the Precambrian Moeda Formation, Minas Gerais, Brazil
David A. Lindsey
1975, Open-File Report 75-264
The middle Precambrian Moeda Formation of Minas Gerais, Brazil, contains uranium and other minerals believed to be of detrital origin. Two areas of anomalously high concentrations of uranium have been discovered in conglomeratic zones that are interpreted as paleochannels. Because the distribution of uranium is believed to be controlled at...
A geologic analysis of the Side-Looking Airborne Radar imagery of southern New England
Paul T. Banks
1975, Open-File Report 75-207
Analysis of the side looking airborn radar imagery of Massachusetts, Connecticut and Rhode Island indicates that radar shows the topography in great detail. Since bedrock geologic features are frequently expressed in the topography the radar lends itself to geologic interpretation. The radar was studied by comparisons with field mapped geologic...
High-gain, long-period seismograph station installation report, Kipapa, Hawaii
Charles R. Hutt
1975, Open-File Report 75-369
A High-Gain, Long-Period Seismograph System, developed by the Lamont-Doherty Geological Observatory, was installed at the Kipapa site of the Honolulu Observatory near Ewa Beach, Oahu, Hawaii in March 1972. Magnifications of 55,000 for the vertical component and 40,000 for the horizontal components were obtained. Velocity data are recorded both photographically...
WATSTORE: National Water Data Storage and Retrieval System of the U. S. Geological Survey; user's guide
Norman E. Hutchison
1975, Open-File Report 75-426
The U.S. Geological Survey investigates the occurrence , quantity, quality, distribution, and movement of the surface and underground water resources of the Nation. The investigations, which are conducted by the Water Resources Division, of the Survey include: systematic collection, analysis, and interpretation of water data; investigation of in and agricultural...
Origin and age of postglacial deposits and assessment of potential hazards from future eruptions of Mount Baker, Washington
Jack H. Hyde, Dwight Raymond Crandell
1975, Open-File Report 75-286
Eruptions and other geologic processes at Mount Baker during the last 10,000 years have repeatedly affected adjacent areas, and especially the valleys that head at the volcano. Most mudflows from the volcano were caused by massive avalanches of volcanic rock that had been partly altered to clay by steam and...
Metallogenic provinces of the southeastern Pacific region
George Edward Ericksen
1975, Open-File Report 75-263
Metalliferous mineral deposits of the southeastern Pacific region include: (1) hydrothermal, magmatic, and sedimentary deposits of the Andean region, one of the great mineral belts of the world; 2) Scattered hydrothermal mineral occurrences in the Antarctic Peninsula; and 3) metal-enriched pelagic sediments, ferromanganese nodules, and volcanic rocks(?) in the southeast...
