Geochemistry of metavolcanic rocks from the Ranyah area, Kingdom of Saudi Arabia
Robert C. Greene
1985, Open-File Report 85-1
Major-element analyses of 26 samples from seven map units of metavolcanic rocks from the Ranyah area are compared with analyses in the literature of rocks from known tectonic settings. The evidence suggests that most of the layered rocks of the Ranyah area originated in immature island arcs. The Khaniq formation...
Paleomagnetic investigations at Mahd adh Dhahab, Kingdom of Saudi Arabia
M. E. Gettings
1985, Open-File Report 85-15
Paleomagnetic studies of 25 oriented bedrock specimens from Jabal Mahd adh Dhahab, located 160 km southeast of Al Madinah, Kingdom of Saudi Arabia, have yielded important structural information relating to the geologic history of this base and precious metal deposit. Samples were collected along one traverse away from the mineralized...
The Salma Caldera complex, northeastern Arabian Shield, Kingdom of Saudi Arabia
K.S. Kellogg
1985, Open-File Report 85-370
The upper Proterozoic Salma caldera is genetically part of an elongate alkali granitic massif, Jabal Salma. Comenditic ash-flow tuffs, the oldest recognized rocks of the caldera complex, were erupted during caldera collapse associated with the rapid evacuation of the upper, mildly peralkaline part of a zoned magma reservoir. Within the...
Ground-water contribution to the salinity of the Upper Colorado River Basin
J. W. Warner, F.J. Heimes, R.F. Middelburg
1985, Water-Resources Investigations Report 84-4198
A study was conducted to estimate the contribution of groundwater and other natural sources to the salinity of streamflow in the Upper Colorado River Basin. Salt-load estimates were derived from a mass balance using measurements of quantity and quality of base streamflow. Groundwater inflow was considered to represent the bulk...
Water resources data, Texas, water year 1984; Volume 2. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
H.D. Buckner, E.R. Carrillo, H.J. Davidson
1985, Water Data Report TX-84-2
Surface-water data for the 1984 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also...
Water resources data, Florida, water year 1983; Volume 1B: Northeast Florida ground water
Water Resources Division, U.S. Geological Survey
1985, Water Data Report FL-83-1B
Water resources data for the 1983 water year for northeast Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
Satellite data-relay activities in Arizona
F. C. Boner, J.W. Blee, W.G. Shope
1985, Water-Resources Investigations Report 85-4158
The U.S. Geological Survey (USGS) Arizona District collects data from automated streamflow stations for a wide variety of uses. Data from these stations are provided to Federal, State, and local agencies that have a responsibility to issue flood warnings; to generate forecasts of water availability; to monitor flow to insure...
