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...
An experiment to test hole-to-hole resistivity measurements for locating mine openings in coal seams
Jeffrey J. Daniels, James Henry Scott
1980, Open-File Report 80-895
Hole-to-hole resistivity measurements can be useful for interpreting resistivity anomalies that are located too far away from the borehole to be detected with conventional well logging probes. Hole-to-hole direct current resistivity measurements are shown in this study to be useful for detecting mine openings in a coal seam....

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....

The oilspill risk analysis model of the U. S. Geological Survey
R. A. Smith, J. R. Slack, T. Wyant, K.J. Lanfear
1980, Open-File Report 80-687
The U.S. Geological Survey has developed an oilspill risk analysis model to aid in estimating the environmental hazards of developing oil resources in Outer Continental Shelf (OCS) lease areas. The large, computerized model analyzes the probability of spill occurrence, as well as the likely paths or trajectories of spills in...
Borehole geophysical measurements for hole UE25-3, Nevada Test Site, Nuclear Waste Isolation Program
Jeffrey J. Daniels, James H. Scott
1980, Open-File Report 80-126
Borehole geophysical measurements made in drill hole UE25a-3 with a U.S. Geological Survey research well-logging truck are presented in this paper. The purpose of these logging measurements is to provide in-situ physical properties information that is not commercially available on drill hole UE25a-3. Well logs are presented in this paper...

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...

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...
Dissolved-solids concentrations and loads in return flows to the Colorado River from agricultural land in southern California
John M. Klein, Wesley L. Bradford
1980, Water-Resources Investigations Report 80-52
The dissolved-solids concentration in Colorado River water increases from less than 50 mg/L (milligrams per liter) at the river's origin to about 700 mg/L at the California border and to about 900 mg/L at the United States-Mexico boundary. Much of the latter increase is due to depletion by agricultural use...
