Geology of the Monterey Bay region
H. Gary Greene
1977, Open-File Report 77-718
Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history. Uplift and depression have produced a succession of regressive and transgressive sedimentary units, while contemporaneous...
Particle size of sediments collected from the bed of the Amazon River and its tributaries in June and July 1976
Carl F. Nordin Jr., R.H. Meade, H.A. Mahoney, B.M. Delany
1977, Open-File Report 77-400
Sixty-five samples of bed material were collected from the Amazon River and its major tributaries between Belem, Brazil, and Iquitos, Peru. Samples were taken with a standard BM-54 sampler, a pipe dredge, or a Helley-Smith bedload sampler. Most of the samples have median diameters in the size range of fine...
Channel erosion surveys along the TAPS route, Alaska, 1977
Robert M. Loeffler, Joseph M. Childers
1977, Open-File Report 78-611
Channel surveys were made along the trans-Alaska pipeline system (TAPS) route during 1977 at the same 28 sites that were studied in 1976. In addition, a new site at pipeline mile 22 near Deadhorse (alignment No 134) along the Sagavanirktok River was put under surveillance. Except for changes wrought by...
Correlation of major eastern earthquake centers with mafic/ultramafic basement masses
Martin Francis Kane
1977, Open-File Report 77-134
Extensive gravity highs and associated magnetic anomalies are present in or near seven major eastern North American earthquake areas as defined by Hadley and Devine (1974). The seven include the five largest of the eastern North American earthquake .centers. The immediate localities of the gravity anomalies are, however, relatively free...
Interpretation of an aeromagnetic anomaly in McMullen and Live Oak counties, Texas
Joseph S. Duval, R.A. Martin
1977, Open-File Report 77-768
An anomaly about 300 gammas in amplitude has been observed in data from an aerial magnetic survey flown over parts of Duval, Live Oak, McMullen, and Webb Counties, Tex. A two-and-one-half-dimensional model was used to iterpret the data, and the anomaly is apparently caused by a large mafic body centered...
Water-level records for Adams, Larimer, Logan, Morgan, Sedgwick, Washington, and Weld Counties, Colorado, 1973-77
Thomas J. Major, Kenneth D. Vaught
1977, Open-File Report 77-461
Water levels measured during March 1977 in 350 wells tapping alluvial aquifers in Adams, Larimer, Logan, Morgan, Sedgwick, Washington, and Weld Counties, Colo., are included in this report. Water-level records for the 4 preceding years also are included to serve as references illustrating declining or rising water levels.Water-level measurements made...
Municipal, industrial, and irrigation water use in Washington, 1975
N. P. Dion, W. E. Lum
1977, Open-File Report 77-308
An assessment of water use in 1975 in the 39 counties and 62 Water Resources Inventory Areas of Washington, indicated that 2.49 trillion gallons of water was used for municipal, industrial, and irrigation purposes. That amount represents a 10-percent increase over a similar water-use assessment in 1965, but a slight...
Background studies for appraising subsidence in the Texas Gulf Coast region
B. E. Lofgren
1977, Open-File Report 77-412
Significant ground movement has accompanied the extraction of large quantities of fluids from the subsurface at many localities. The possibility of both horizontal and vertical ground movement--subsidence, fissuring, growth faulting--in the Gulf Coast region, caused by the withdrawal of large volumes of deep formation fluids, is of major concern.Although widespread...
Late diagenetic indicators of buried oil and gas
Terrence J. Donovan, Mary C. Dalziel
1977, Open-File Report 77-817
At least three hydrocarbon seepage mechanisms are interpreted to operate over oil and gas fields. These are: (1) effusion ofh ydrocarbons through inadequate caprocks and along faults and fractures, (2) low-molecular-weight hydrocarbons dissolved in water moving vertically through capping shales as a result of a hydrodynamic or chemical potential drive,...
Uranium and thorium distribution in soils and weathered bedrock in south Texas
Kendell A. Dickinson
1977, Open-File Report 77-764
The distribution of uranium and thorium in soils and weathered bedrock in areas of calich soil development on various kinds of sedimentary bedrock in south Texas indicates that uranium and thorium are leached from the surface layers and deposited deeper in the soil or weathered bedrock. The data provide field...
