Analyses of geochemical samples and descriptions of rock samples, Adams Gap and Shinbone Creek Roadless Areas, Clay County, Alabama
M. S. Erickson, J.T. Hanley, D. L. Kelley, L.J. Sherlock
1983, Open-File Report 83-335
Semiquantitative spectrographic analyses for 31 elements on 105 rocks, 47 stream-sediment, and 70 soil samples from the Adams Gap and Shinbone Creek Roadless Areas and vicinity, Talladega National Forest, Clay County, Alabama are reported here in detail. Atomic-absorption analyses for zinc in all samples and for gold in 5 selected...
Ground-water hydrology before, during, and after coal strip mining of a small watershed in Coshocton County, Ohio
A. C. Razem
1983, Water-Resources Investigations Report 83-4155
Ground-water conditions before, during, and after surface mining of a small watershed are described as part of a study to determine the effects of mining on hydrologic systems. The watershed was underlain by stratified sedimentary rocks containing three aquifers. The top and middle aquifers were perched above clay beds that...
Comparison of abundances of chemical elements in mineralized and unmineralized sandstone of the Brushy Basin Member of the Morrison Formation, Smith Lake District, Grants uranium region, New Mexico
C. T. Pierson, C.S. Spirakis, J. F. Robertson
1983, Open-File Report 83-818
Statistical treatment of analytical data from the Mariano Lake and Ruby uranium deposits in the Smith Lake district, New Mexico, indicates that organic carbon, arsenic, barium, calcium, cobalt, copper, gallium, iron, lead, manganese, molybdenum, nickel, selenium, strontium, sulfur, vanadium, yttrium, and zirconium are concentrated along with uranium in primary ore....
Time-domain electromagnetic tests in the Wadi Bidah District, Kingdom of Saudi Arabia
Vincent J. Flanigan, Hamdy Sadek, Bruce Smith, C. L. Tippens
1983, Open-File Report 83-613
A time-domain electromagnetic (TDEM) method was tested in two areas of mineralization in Precambrian rocks in the Wadi Bidah district, Kingdom of Saudi Arabia. Transient-decay voltages in profile mode were measured across the Sha'ab at Tare and Rabathan prospects by use of three transmitterreceiver loop configurations. At the Sha'ab at...
Geological and geochemical studies in the Wadi Bidah District, Kingdom of Saudi Arabia
C. W. Smith, B.C. Waters, M. Naqvi, R. G. Worl, A. M. Helaby, V. J. Flanigan, H.S. Sadek, R.M. Samater
1983, Open-File Report 83-672
Geological and geochemical followup studies of airborne electromagnetic anomalies in the Wadi Bidah district, southwestern Saudi Arabia, did not reveal metals of economic grade. Investigation of an anomaly enclosing the Rabathan ancient mine disclosed tightly folded and sheared Proterozoic tuffaceous rocks interlayered mostly with chert, dolomite, carbonaceous rocks, and volcanic...
Water resources on the Pueblo of Laguna, west-central New Mexico
D. W. Risser, F. P. Lyford
1983, Water-Resources Investigations Report 83-4038
This study evaluates the quality and quantity of water available on the Pueblo of Laguna, New Mexico. Groundwater for public supply occurs in the valley fill along the Rio San Jose, in the Paguate and Encinal areas, and possibly in the northern part of the Sedillo Grant. The valley fill...
Selected hydrologic data, Kolob-Alton-Kaiparowits coal-fields area, south-central Utah
Gerald G. Plantz
1983, Open-File Report 83-871
The Kolob-Alton-Kaiparowits coal-field area (pi. 1) includes about 4,500 square miles in parts of the Colorado River Basin and the Great Basin. The area varies in altitude from less than 4,000 to more than 10,000 feet, and is comprised chiefly of plateaus, benches, and terraces that are dissected by deep,...
