Geophysical logs and coal sections for four holes drilled in the Emery East quadrangle, Emery County, Utah
Eugene G. Ellis
1980, Open-File Report 80-1027
Four holes, for a total of 2,330 feet, were drilled in the Emery coal field, Utah, in April 1980 by the U.S. Geological Survey (fig. 1). Two of the holes were partially cored. The purpose of the drilling was to obtain information on the thickness, quality, and extent of the...
Mekometer measurements in the Imperial Valley, California, 1980

1980, Open-File Report 81-1141
During a six-week period in the Spring of 1980, approximately seven months after the October 15, 1979 earthquake, parts of the Imperial Valley mekometer network (Fig. 1) were re-measured for comparison with measurements made during the twelve months preceding the earthquake and the six weeks following it. The purpose was...

Potassium-argon geochronology of the eastern Transverse Ranges and southern Mojave Desert, southern California
F. K. Miller, D. M. Morton
1980, Professional Paper 1152
More than 200 potassium-argon apparent ages on minerals from crystalline rocks, chiefly from the San Bernardino and eastern San Gabriel Mountains and the southern Mojave Desert, define an area greater than 10,000 km2 in which the potassium-argon isotopic systematics have been highly disturbed. The disturbance or disturbances appear to have...
Catalog of earthquakes along the San Andreas fault system in Central California, January-March 1977
S.M. Marks, F.W. Lester
1980, Open-File Report 80-1233
Numerous small earthquakes occur each day in the Coast Ranges of central California. The detailed study of these earthquakes provides a tool for gaining insight into the tectonic and physical processes responsible for the generation of damaging earthquakes...
Quality of water and time of travel in Yockanookany River, Choctaw County, Mississippi
Gene A. Bednar
1980, Open-File Report 80-770
An intensive study of a 3.3-mile reach of the Yockanookany River, including a major tributary, was conducted August 29-31, 1978. The quality-of-water data were collected during a period of generally law streamflow and seasonally high air temperatures. These data show that the quality of water in Yockanookany River was generally...
Holocene geomagnetic secular variation in the western United States: implications for the global geomagnetic field
Duane E. Champion
1980, Open-File Report 80-824
A record of Holocene geomagnetic secular variation in the western 14 United States has been measured from volcanic rocks dated by 14C. Analysis of errors associated with the paleomagnetic techniques used suggests that all laboratory measurement errors are smaller than those introduced by deformation of the volcanic units and the...
Hydrogeologic data for the Mississippi Embayment of southeastern Missouri
Richard R. Luckey, Dale L. Fuller
1980, Open-File Report 79-421
The Mississippi embayment of southeastern Missouri is a 4 ,000-square-mile agricultural area that is presently (1979) undergoing rapid development for irrigation. In July 1974, a project was initiated to evaluate the water resources of the area, determine the extent of irrigation, and to assess the future potential for irrigation supplies....

210Pb-determined sedimentation rates and trace-metal concentrations, upper Klamath Lake and Lake Euwana, Oregon
E. Ann Martin, Cynthia A. Rice
1980, Open-File Report 80-2016
Rates of sedimentation calculated from analyses of 210Pb activities in cores from Upper Klamath Lake and Lake Euwana (Klamath County, Ore.) indicate that the lakes, whose mean depths are 2.4 m, are filling at approximately 3.5 mm/yr. In Upper Klamath Lake, average accumulation rates range from 0.9 mm/yr at a...

Water-supply assessment of the Laramie-Fox Hills aquifer in parts of Adams, Boulder, Jefferson, and Weld Counties, Colorado
Paul A. Schneider
1980, Open-File Report 80-327
Groundwater in the Laramie-Fox Hills aquifer is a potential source of supplemental municipal water supplies for the communities of Erie, Lafayette, Louisville, and Superior in Colorado. The present water supplies for these communities are not always adequate to meet current demands. The U.S. Geological Survey made a water-supply assessment of...
