1978, Open-File Report 78-771
Four deposits in the Wadi Bidah district of southwestern Saudi Arabia were explored during the period 1972-1974. The work consisted of geologic, geochemical, and geophysical investigations and diamond drilling in the subsurface. Thirteen holes were drilled, aggregating a length of 2,397 m. Drilling at three of the deposits, Gehab, Sha'ab...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: July 1978
J.B. Townshend, J.E. Papp, S.P. Tilton
1978, Open-File Report 78-300-G
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Water quality in the Old Plantation Water Control District, Broward County, Florida; progress report, July 1976-June 1977
Gary M. Russell, Chris E. Hanson, William A.J. Pitt
1978, Open-File Report 78-411
Water quality in the Old Plantation Water Control District in Broward County, Florida has been affected by effluent from sewage-treatment plants, agriculture, and storm-water runoff. Effect of the effluent from sewage-treatment plants on water quality was evident at 3 sites where concentrations of nutrients and bacteria in the Broward County...
A 500-volt pulse transmitter for ice sounding
Charles J. Roubique
1978, Open-File Report 78-372
A high-voltage pulser developed by the U.S. Geological Survey for glacier soundings is a small battery-operated unit that weighs about one kg and was packaged in a case measuring 8.2 X 12 X 18.8 cm. It operates from an external 12 volt battery and supplies a 500-V pulse to a...
Asbestos occurrences in serpentinites of the Hamdah area, Kingdom of Saudi Arabia
Lawrence Frederick Rooney, Ziad H. Al-Koulak
1978, Open-File Report 79-360
A cluster of serpentinite bodies centered at 19°00'N. and 43°45'E., near the village of Hamdah, contain many occurrences of the fibrous asbestos minerals chrysotile and anthophyllite. In the south-central part of the area, near the ancient Hajr gold mine (18°54'45"N. and 43°40'30"E.), the fiber is of fair quality and grade...
Description of wells at Beale Air Force Base and vicinity, California
Gerald L. Rockwell
1978, Open-File Report 78-10
The study area occupies approximately 168 square miles of the Sacramento Valley. The study area boundary is the Yuba River in the north, the Feather River in the west, the Bear River in the south, and the Sierra Nevada foothills in the east. Between December 1976 and March 1977, 640 wells...
Preliminary sulfur isotope investigations of mineral deposits in the Precambrian shield, Kingdom of Saudi Arabia
Ralph Jackson Roberts, Robert O. Rye, Mustafa M. Mawad
1978, Open-File Report 78-776
Massive sulfide deposits and sulfide-bearing veins in Saudi Arabia show a wide range in δ34S values from very negative to strongly positive and cover almost the entire range observed for ore deposits in nature.Massive sulfide deposits that have very negative values (Wadi Wassat and Wadi Qatan) formed as syngenetic sedimentary...
Ground water withdrawn for municipal, industrial, and irrigation use in the Upper Peace and Alafia River basins, west-central Florida, 1970-74
Alton F. Robertson, L. R. Mills, D.C. Parsons
1978, Open-File Report 78-29
Data are presented for ground-water withdrawals for municipal, industrial and irrigation use in the upper Peace and Alafia River basins during 1970-71. Within the 1,160-square-mile study area, the principal source of ground water is the Floridan aquifer. Methods used to determine ground-water withdrawal include: metering water use; relating measured well...
Monitoring water-quality during pilot-dredging operations in the Willamette and Columbia Rivers, Oregon
Joseph F. Rinella, Stuart W. McKenzie
1978, Open-File Report 78-554
Water quality was monitored in the Willamette and Columbia Rivers during a pilot dredging operation on December 16, 1977. Monitoring included in-situ measurements of pH, temperature, dissolved oxygen, and conductivity in the Willamette and Columbia Rivers; analyses of dissolved ammonia, dissolved manganese, suspended-sediment concentration and particle size, loss on ignition,...
Scatter diagrams and correlations of uranium in surface water versus discharge, conductivity, and pH at various locations throughout the United States
Jennie L. Ridgley, Karen J. Wenrich-Verbeek
1978, Open-File Report 78-581
A study of the relationship of stream discharge, conductivity, and pH with uranium concentration in surface waters has been made for various locations in the United States utilizing data collected, for the most part, by the U.S. Geological Survey (USGS). The results of the study are portrayed by the scatter...
