New potassium-argon data on the age of mineralization and metamorphism in the Willow Creek mining district, southern Talkeetna Mountains, Alaska
Miles L. Silberman, Bela Csejtey Jr., James G. Smith, Marvin A. Lanphere, Frederic H. Wilson
1978, Circular 772-B
The now largely abandoned Willow Creek mining district, southern Talkeetna Mountains, Alaska, produced nearly $18,000,000 in gold and minor silver between 1909 and the early 1950's. Mineralized quartz veins, which contain gold and silver along with minor quantities of base metals (in pyrite, galena, chalcopyrite, sphalerite, molybdenite, and arsenopyrite), cut...
Flame and flameless atomic-absorption determination of tellurium in geological materials
T. T. Chao, R. F. Sanzolone, A.E. Hubert
1978, Analytica Chimica Acta (96) 251-257
The sample is digested with a solution of hydrobromic acid and bromine and the excess of bromine is expelled. After dilution of the solution to approximately 3 M in hydrobromic acid, ascorbic acid is added to reduce iron(III) before extraction of tellurium into methyl isobutyl ketone (MIBK). An oxidizing air-acetylene...
Low-flow characteristics of streams in the Rock-Fox River basin, Wisconsin
B. K. Holmstrom
1978, Water-Resources Investigations Report 78-85
Low-flow characteristics of streams in the Rock-Fox River basin, Wis., include estimates of low-flow frequency ad flow duration at 13 gaging stations; low-flow frequency characteristics at 32 low-flow partial-record stations and 78 miscellaneous sites; and a list of base-flow discharge measurements at 244 miscellaneous sites. Equations are provided to estimate...
Hydrologic appraisal of the water resources of the Homer-Preble Valley, New York
William Buller
1978, Water-Resources Investigations Report 78-94
Water resources of Homer-Preble Valley, 1 to 2 miles wide and 9 miles long, in central New York, were appraised because the area is expected to undergo considerable residential development in the near future. The main source of water supply to the residents of the area is the glacial-outwash aquifer....
Preliminary analytical results for a new U.S. Geological Survey Devonian Ohio Shale Standard SDO-1
Joel S. Leventhal, J.G. Crock, W. Mountjoy, J.A. Thomas, V.E. Shale, Paul H. Briggs, J.S. Wahlberg, M.J. Malcolm
1978, Open-File Report 78-447
Using several analytical techniques, results of analysis of U. S. Geological Survey new standard SDO-1 are given for selected elements. The Devonian black shale shows an organic carbon content of approximately 10.3 percent, a sulfur content of approximately 5.6 percent, and a uranium content of approximately 56 ppm. Some elements...
Potentiometric surface of the Mississippian aquifer in parts of Trigg, Lyon, Caldwell, and Christian Counties, Mississippian Plateau region, Kentucky
Raymond O. Plebuch
1978, Water-Resources Investigations Report 78-25
Ground-water levels in a 600 square mile area of the Cumberland River drainage basin in parts of Trigg, Lyon Caldwell, and Christian Counties, Mississippian Plateau Region, Kentucky are shown by means of contours on the potentiometric surface. Generaly, ground water moves toward and with the surface drainage to Lake Barkley...
