Computer program for the calculation of grain size statistics by the method of moments
Michael B. Sawyer
1977, Open-File Report 77-580
A computer program is presented for a Hewlett-Packard Model 9830A desk-top calculator (1) which calculates statistics using weight or point count data from a grain-size analysis. The program uses the method of moments in contrast to the more commonly used but less inclusive graphic method of Folk and Ward (1957). The...

Terrigenous clastic sediments of the Upper Cretaceous Mesaverde Group (Campanian) in the southeastern part of the Yampa coal field in Routt County, northwestern Colorado, contain many beds of bituminous coal. Lower, middle, and upper coal groups are recognized. The middle coal group, in the lower coal-bearing member of the Williams...
Water table in the surficial aquifer and potentiometric surface of the Floridan Aquifer in selected well fields, west-central Florida, September 1976
Paul D. Ryder, L. R. Mills
1977, Open-File Report 77-551
The water table in the surficial aquifer and the potentiometric surface of the Florida aquifer in a 1200 square-mile area in west-central Florida are mapped semiannually by the U. S. Geological Survey. Maps are prepared on the basis of water levels measured in wells each May to coincide with seasonal...
Subsurface-temperature data for some wells in western Utah
F. Eugene Rush
1977, Open-File Report 77-132
The data contained in this report were gathered as part of a hydrothermal reconnaissance of the State of Utah. These data, plus additional data and information, will form the basis for a future interpretive report. These data are being released separately from and prior to the interpretive report, to make...

Seismicity of the Pahute Mesa area, Nevada Test Site: 8 October 1975 to 30 June 1976
A. M. Rogers, Geraldine M. Wuollet, P. A. Covington
1977, Open-File Report 77-826
A total of 1,075 earthquakes occurred in the Pahute Mesa area with 2.5≤ML≤4.9 during the period October 28, 1975, to June 28, 1976. The majority of these earthquakes are aftershocks of the nuclear events, Kasseri, Inlet, Muenster, Fontina, Cheshire, Estuary, Colby, and Pool (5.8≤ML≤6.3). Smaller nuclear events (ML≤5.5) on Rainier...

Reconnaissance of sedimentation in the Rio Pilcomayo Basin, May 1975, Argentina, Bolivia, and Paraguay
John R. Ritter
1977, Open-File Report 77-327
The Río Pilcomayo "Alto" (Bolivia) and "Superior" (Bolivia, Argentina, and Paraguay) transport large quantities of sediment for the size of the basin. The Río Pilcomayo "Inferior" (Argentina and Paraguay) seems to carry little sediment. The large loads of the "Alto" and "Superior" must be considered before dams or irrigation projects...
A brief investigation of the surface-water hydrology of Yemen Arab Republic
Henry Chiles Riggs
1977, Open-File Report 77-150
Yemen, near the southwest tip of the Arabian Peninsula, is a mountainous country bordered by a desert on the east and a coastal plain on the west. Rainfall is low and seasonal; consequently, most streams (wadis) are ephemeral. The natural flow regimens of many of the smaller wadis are modified...
Atlantic Margin Coring Project 1976: Preliminary Report on Shipboard and Some Laboratory Geotechnical data
Adrian F. Richards
1977, Open-File Report 78-123
This report presents reduced shipboard geotechnical data collected during the 1976 Atlantic Margin Coring Project; results of laboratory tests of specific gravity, water content, bulk density, and Atterberg limits; and sedimentation-compression e log p curves showing consolidation. A description of the procedures used at sea and in the laboratory and...

Linear-traverse surveys of helium and radon in soil gas as a guide for uranium exploration, central Weld County, Colorado
G. Michael Reimer, R.S. Rice
1977, Open-File Report 77-589
Linear-traverse surveys of helium and radon in soil gas were performed and evaluated as a guide for uranium exploration in central Weld County, Colo. Repeated sampling over a 5-month period eventually delineated a helium anomaly along the main 11.2 km traverse, and that anomaly may be related to a uranium...
