A. Buono, K.W. Causseaux, J.E. Moore
1978, Open-File Report 78-331
This report summarizes the activities of the Southwest Florida Subdistrict of the U.S. Geological Survey, Water Resources Division for fiscal year 1977. The organization and mission of the subdistrict office are described. The cooperative program for fiscal year 1977 included 41 interpretive investigations. Abstracts of twenty reports released by the...
Placer gold deposits in the Mahd adh Dhahab district, Kingdom of Saudi Arabia
Abdulaziz Y. Bagdady, Jesse William Whitlow, Ralph Jackson Roberts
1978, Open-File Report 78-1074
Placer gold deposits in the Mahd adh Dhahab district were productive during ancient times, possibly during two periods, about 950 B.C. and 750— 1258 A.D. These deposits were mapped and systematically sampled in 1973 to determine their future potential. The sampling program was facilitated by use of a backhoe which...
RFM (relative fraction magnitude): program explanation and computer program listing
Henry V. Alminas, George Van Trump
1978, Open-File Report 78-1013
The RFM (relative fraction magnitude) program is proposed as an aid in the estimation of depth to ore-mineral concentration. This estimate is based on the determination of the relative position of the sampled surface plane within the zonational framework of a hydrothermal sulfide mineralization. The program requires analytical data on...
Interpretation of electromagnetic extra-low-frequency soundings in the Randsburg, California, Known Geothermal Resource Area
Walter L. Anderson
1978, Open-File Report 78-562
An electromagnetic (EM) controlled source survey was made during the period Nov. 30, 1977, to Dec. 13, 1977, in the Randsburg, California, Known Geothermal Resource Area (KGRA). This report summarizes the observed extra-low-frequency (ELF) data and least squares interpretation using a computer program developed by Anderson (1977). The results are...
Potential potable-water supplies in Redwood National Park, California
J. P. Akers
1978, Open-File Report 78-970
An evaluation was made of the potential for potable-water supplies at 13 sites in or near Redwood National Park, Calif. The National Park Service is planning for the development of visitor facilities at these sites. At some sites, the report recommends using surface-water diversions. At other sites, locations are given...
Notes on acquisition of high-resolution seismic profiles in southern Puget Sound, Washington
P. D. Snavely Jr., H. D. Gower, J. C. Yount, J. E. Pearl, A. R. Tagg, J.W. Lee, D.L. Lander
1978, Open-File Report 78-328
Approximately 275 km of high-resolution seismic reflection profiles were obtained in Puget Sound, Washington from the U.S. Geological Survey's research vessel DON J. MILLER from January 13 through 19, 1976. These data, recorded on microfilm, were obtained to provide information on the thickness and distribution of Quaternary deposits, to identify folds and faults that deform...
Water budget and water-surface fluctuations, Great Salt Lake, Utah
Ted Arnow
1978, Open-File Report 78-912
The water-budget equation for Great Salt Lakes is: Inflow = Outflow + or - Storage change. The average annual inflow for the period 1931-76 was about 2.9 million acre-feet; 1.9 million acre-feet from surface sources, about 900,000 acre-feet from direct precipitation, and about 75,000 acre-feet from ground water. The average...
Analyses and description of soil samples from Mountain Lake and Peters Mountain Wilderness Study areas, Virginia and West Virginia
J. M. Motooka, Craig A. Curtis, Frank Gardner Lesure
1978, Open-File Report 78-1077-A
Semiquantitative emission spectrographic analyses for 30 elements and atomic absorption analysis for zinc on 98 soil samples are reported here in detail. Location for all samples are in Universal Transverse Mercator (UTM) coordinates. A few samples of soil developed on Lower Devonian sandstone and chert contain more barium and zinc...
Determination of peak discharge from rainfall data for urbanized basins, Wichita, Kansas
C.O. Peek, P. R. Jordan
1978, Open-File Report 78-974
Rainfall and runoff data from urbanized drainage basins in the Wichita area, Kansas, were used to evaluate the Soil Conservation Service synthetichydrograph method of computing flood hydrographsfrom rainfall data. The method was tested on six basins where the impervious surface ranged from 11 percent on the least urbanized basin to...
Principal facts for a gravity survey of the Double Hot Springs Known Geothermal Resource Area, Humboldt County, Nevada
Donald L. Peterson, Harold E. Kaufmann
1978, Open-File Report 78-107-A
During July 1977, forty-nine gravity stations were obtained in the Double Hot Springs Known Geothermal Resource Area and vicinity, northwestern Nevada. Elevations for twenty-two stations were estimated from lake bed topographic contours. Horizontal positions for these stations were determined from topographic maps and vehicle odometer. Elevations for stations DBLD34 and...
