Water resources of the Lake Superior watershed, northeastern Minnesota
Perry G. Olcott, D.W. Ericson, P.E. Felsheim, W.L. Broussard
1978, Hydrologic Atlas 582
The Lake Superior watershed is mostly a highland, generally 1,200 feet (366 meters) to 2,000 feet (610 meters) above mean sea level. It extends from Duluth to the Canadian border. Both maximum and minimum altitudes for Minnesota occur in the watershed; 2.301 ft (701 ) at Eagle Mountain, about 12 mi...
Summary of the water resources of Puerto Rico
H.J. McCoy
1978, Open-File Report 78-971
The U.S. Department of Commerce (DOC) is the lead agency in the Federal Interagency Study of the Economy of Puerto Rico. At the request of DOC the U.S. Geological Survey is providing a discussion of the water resources of the island for inclusion in the study's section on macroeconomic assessment.Two...
Mineral exploration, Mahd adh Dhahab District, Kingdom of Saudi Arabia
Ronald G. Worl
1978, Open-File Report 78-1073
Mahd adh Dhahab is the largest of numerous ancient gold mines scattered through the Precambrian shield of Saudi Arabia and the only one with recent production. During the period 1939-54, 765,768 fine ounces of gold and 1,002,029 ounces of silver were produced from the mines by the Saudi Arabian Mining...
Users guide for distributed routing rainfall-runoff model
D.R. Dawdy, John C. Schaake Jr., William M. Alley
1978, Water-Resources Investigations Report 78-90
A computer program of a watershed model for routing urban flood discharges through a branched system of pipes or natural channels using rainfall as input has been developed and documented. The model combines soil-moisture-accounting and rainfall-excess components developed by Dawdy and others (1972) with the kinematic-wave routing method presented by...
Uranium and phosphate resources in the Cooper Formation of the Charleston region, South Carolina
Eric R. Force, G. S. Gohn, L.M. Force, B.B. Higgins
1978, Open-File Report 78-586
Phosphate deposits formerly exploited in the Charleston district were formed by weathering and reworking of the Cooper Formation (Eocene and Oliogcene). Previous workers have shown that unusual concentrations of uranium occur in phosphate-rich nodular material formed during subareal weathering. We found that the old mining district is on an erosional...
Geohydrologic data from twenty-four test holes drilled in the Piceance Basin, Rio Blanco County, Colorado, 1975-76
Frank A. Welder, George J. Saulnier
1978, Open-File Report 78-734
Twenty-four test holes were drilled in the Piceance basin, northwestern Colorado, to obtain geohydrologic data from the Uinta and Green River Formations of Eocene age. Depths of test holes ranged from 640 to 2,800 feet. The maximum quantity of water discharged during the air drilling of individual test holes ranged...
A statistical summary and listing of the spectrographic analyses of heavy mineral concentrate and conventional, sieved stream-sediment samples, Silver City area, New Mexico
K. C. Watts, J.R. Hassemer, D. F. Siems, J. M. Nishi
1978, Open-File Report 78-801
Geochemical sampling of a tier of eight 7 1/2-minute quadrangles bordered by latitudes 32° 45'and 33° 00' N. and longitudes 108° 00' and 108° 30' W. was begun in the fall of 1974 and continued seasonally until completion in the fall of 1976. These quadrangles are in southwest New Mexico...
Allocation of subsamples of Apollo 17 lunar rocks from the boulder at station 7, for study by the International Consortium
Jean A. Minkin, Carolyn L. Thompson, E. C. T. Chao
1978, Open-File Report 78-511
The International Consortium was organized, under the leadership of E. C. T. Chao, to conduct a systematic interdisciplinary study of four lunar rock samples (77135, 77115, 77075 and 77215) collected by the Apollo 17 astronauts as representative of the four lithologies they recognized in the boulder at station 7. Tables...
Analyses and description of geochemical samples, Cranberry Wilderness Study Area, Pocahontas and Webster counties, West Virginia
J. M. Motooka, J.C. Negri, J. D. Sharkey, F. G. Lesure
1978, Open-File Report 78-215
Semiquantitative spectrographic and other analyses on 104 stream sediment and 100 rock and mineral samples are reported here in detail. Location for all samples are in universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock and mineral samples are included. Rocks analyzed include sandstone and shale; two samples of pyrite...
