Environments at U.S. and U.S.S.R. nuclear explosion sites petroleum-stimulation projects
Maurice J. Terman
1970, Open-File Report 71-279
The United States Plowshare program for the peaceful application of nuclear explosives was formally established by the Atomic Energy Commission in 1957. A number of engineering uses for such explosions were proposed and discussed in the late fifties, mostly by personnel of the Lawrence Radiation Laboratory under contract to AEC,...
Accoustical survey of Massachusetts and Cape Cod Bays, western Gulf of Maine
Brian E. Tucholke, Robert N. Oldale, C. D. Hollister
1970, Open-File Report 70-331
The accompanying map shows the amount of acoustic penetration achieved in the sediments of the western Gulf of Maine using a 3.5 kHz echo sounding system and illustrates the pronounced control of topography on sediment distribution. Little or no sub-bottom penetration was observed in areas of sand and gravel on...
Test of airborne fluorometer over land surfaces and geologic materials
George Eimert Stoertz, William R. Hemphill
1970, Open-File Report 70-316
Response of an experimental Fraunhofer line discriminator(FLD) to a wide range of surficial deposits common in deserts and semideserts was tested in the laboratory and from an 1-1-19 helicopter. By design the instrument sensed radiation from the ground specifically at the sodium D2 Fraunhofer line (5890 angstroms). It is capable...
The mineral resources of the Sierra Nevada de Santa Marta, Columbia (Zone I)
Charles McFarland Tschanz, Andres Jimeno V., Jaime B. Cruz
1970, Open-File Report 70-329
The Sierra Nevada de Santa Maria on the north coast of Colombia is an isolated triangular mountain area that reaches altitudes of almost 19,000 feet. The exceedingly complex geology is shown on the 1:200,000 geologic map. Despite five major periods of granitic intrusion, three major periods of metamorphism, and extensive...
Water resources in the Big Lost River Basin, south-central Idaho
E. G. Crosthwaite, C.A. Thomas, K.L. Dyer
1970, Open-File Report 70-93
The Big Lost River basin occupies about 1,400 square miles in south-central Idaho and drains to the Snake River Plain. The economy in the area is based on irrigation agriculture and stockraising. The basin is underlain by a diverse-assemblage of rocks which range, in age from Precambrian to Holocene. The...
Geology of the north end of the Ruby Range, southwestern Montana
Russell G. Tysdal
1970, Open-File Report 70-333
This study consists of two parts: stratigraphy and sedimentation, and structure of rocks in the northern one-third of the Ruby Range of southwestern Montana. Detailed studies of Cambrian marine dolomite rocks in the Red Lion Formation and in the upper part of the Pilgrim Limestone resulted in their division into...
