Research and development program for outer continental shelf oil and gas operations, report for fiscal year 1978
John B. Gregory
1978, Open-File Report 78-902
This report summarizes the contract research program in support of the Geological Survey's Outer Continental Shelf oil and gas operations. The program is technological, though certain environmental investigations are being conducted as a necessary adjunct. The program manager provides a focal point for communicating with the research community in both...
Summary of hydrologic data collected during 1976 in Dade County, Florida
John E. Hull
1978, Open-File Report 78-883
During 1976 rainfall was 1.58 inches below the long-term average. Ground-water levels ranged from 0.4 foot above to 0.5 foot below average. The highest and lowest ground water for the year were both 1 foot below their long-term averages. In the Hialeah-Miami Springs area, water levels in wells near the...
Effects of coal mine subsidence in the western Powder River basin, Wyoming
C. Richard Dunrud, Frank W. Osterwald
1978, Open-File Report 78-473
Analyses of the surface effects of past underground coal mining in the western Powder River Basin suggest that underground mining of strippable coal deposits will damage the environment more over long periods of time than will modern surface mining, provided proper restoration procedures are followed after surface mining. Subsidence depressions...
Geology of the uranium prospect at Camp Smith, New York, with a new model for the formation of uranium deposits in metamorphosed submarine volcanogenic rocks
Richard I. Grauch
1978, Open-File Report 78-949
Uraninite of Precambrian age occurs locally in and around a massive sulfide deposit at Camp Smith, Westchester and Putnam Counties, New York. The host rocks are believed to be part of a sequence of marine sediments and submarine volcanogenic rocks that were metamorphosed to leucogneisses, amphibolites, and amphoholite gneisses in...
Analyses of rock samples from the Hunt Fork Shale and related Upper Devonian rocks, Philip Smith Quadrangle, Arctic Alaska
J. Thomas Dutro, David E. Detra
1978, Open-File Report 78-559
More than 1400 m of fine-grained clastic rocks and reefoid limestones constitute the lower part of an Upper Devonian transgressive-regressive cycle in the central Brooks Range, Alaska (Dutro and others, 1977). The Hunt Fork Shale and an underlying heterogeneous unit (unnamed) were measured and sampled on the east side of...
A computer program for simulating salinity loads in streams
Kent C. Glover
1978, Open-File Report 78-884
A FORTRAN IV program that simulates salinity loads in streams is described. Daily values of stream-discharge in cubic feet per second, or stream-discharge and specific conductance in micromhos, are used to estimate daily loads in tons by one of five available methods. The loads are then summarized by computing either...
Geologic map of the Coprates Quadrangle of Mars
J.F. McCauley
1978, IMAP 897
The Coprates quadrangle lies to the east of the Tharsis volcanic complex and the Noctis Labyrinthus tectonic complex. To the north are the plains of Lunae Planum, to the east the vast patches of chaotic terrain and the large sinuous channels that trend northward to the Chryse Planitia. On...
Reconstruction of crustal blocks of California on the basis of initial strontium isotopic compositions of Mesozoic granitic rocks
Ronald Wayne Kistler, Zell E. Peterman
1978, Professional Paper 1071
Initial 87Sr/ 86 Sr was determined for samples of Mesozoic granitic rocks in the vicinity of the Garlock fault zone in California. These data along with similar data from the Sierra Nevada and along the San Andreas fault system permit a reconstruction of basement rocks offset by the Cenozoic lateral...
Geologic map of the Amazonis Quadrangle of Mars
E. C. Morris, S.E. Dwornik
1978, IMAP 1049
The Amazonis quadrangle lies within the northern sparsely cratered hemisphere of Mars (Carr and others, 1973) The dominant structural ad physiographic features of the quadrangle are...
Potential sites for a spent unreprocessed fuel facility (SURFF), southwestern part of the Nevada Test Site
D. L. Hoover, Edwin Butt Eckel, Jane P. Ohl
1978, Open-File Report 78-269
In the absence of specific criteria, the topography, geomorphology, and geology of Jackass Flats and vicinity in the southwestern part of the Nevada Test Site are evaluated by arbitrary guidelines for a Spent Unreprocessed Fuel Facility. The guidelines include requirements for surface slopes of less than 5 percent, 61 m...
