Collection, chemical analysis, and evaluation of coal samples in 1975
Vernon Emanuel Swanson, J.H. Medlin, J. R. Hatch, S.L. Coleman, G.H. Wood Jr., S.D. Woodruff, R.T. Hildebrand
1976, Open-File Report 76-468
During 1975, the U.S. Geological Survey, in cooperation with other Federal and State agencies, university groups, and private companies, continued its program to augment and refine information on the composition of coal in the United States. This report includes all analytical data on 799 channel samples of coal beds from...
Radioactive mineral springs in Delta County, Colorado
Robert A. Cadigan, John N. Rosholt, J. Karen Felmlee
1976, Open-File Report 76-223
The system of springs in Delta County, Colo., contains geochemical clues to the nature and location of buried uranium-mineralized rock. The springs, which occur along the Gunnison River and a principal tributary between Delta and Paonia, are regarded as evidence of a still-functioning hydrothermal system. Associated with the springs are...
Geological reconnaissance of some Uruguayan iron and manganese deposits in 1962
Roberts Manning Wallace
1976, Open-File Report 76-466
The Valentines iron deposit, Florida, Uruguay This report is the result of a request by the Uruguayan Government for technical assistance in the field of geology by the U.S. Geological Survey under the auspices of the U.S. Agency for International Development and the Corps of Engineers, United States Army. Geological reconnaissance...
Mean annual runoff in the upper Ohio River basin, 1941-70, and its historic variation
Robert M. Beall
1976, Open-File Report 76-384
A map of the Ohio River basin above the Muskingum River shows patterns of mean annual runoff for the climatologic and hydrologic reference period, 1941-70. The primary data base consisted of 98 long-term gaging-station records collected within this 27,300-square-mile headwater area of the Ohio River basin. Supplemental information was derived...
Hydrology of the solid waste burial ground as related to potential migration of radionuclides, Idaho National Engineering Laboratory
Jack T. Barraclough, J.B. Robertson, V.J. Janzer, L.G. Saindon
1976, Open-File Report 76-471
A study was made (1970-1974) to evaluate the geohydrologic and geochemical controls on subsurface migration of radionuclides from pits and trenches in the Idaho National Engineering Laboratory (INEL) solid waste burial ground and to determine the existence and extent of radionuclide migration from the burial ground. A total of about...
Geologic interpretation of an aeromagnetic map of the west-central Columbia Plateau, Washington and Oregon
Donald A. Swanson, Thomas L. Wright, Isidore Zietz
1976, Open-File Report 76-51
A low altitude, total intensity aeromagnetic map of the ?west-central Columbia Plateau, underlain principally by the Yakima Basalt,. shows Positive and negative anomalies that stand out from a moderate intensity .background reflecting .interbedded flows of normal and reversed magnetic polarity. One set of anomalies is related to anticlinal ridges, nother...
The hydrologic setting of lakes in Minnesota and adjacent states; with emphasis on the interaction of lakes and ground water
Thomas C. Winter
1976, Open-File Report 76-81
The hydrologic settings of 150 randomly-selected lakes in the north-central United States were investigated by principal component analysis as a first attempt to develop a general classification of the hydrologic setting of lakes. Precipitation-evaporation balance and the water quality parameters have high factor loadings on the first principal component. Highest...
