Digital models of a glacial outwash aquifer in the Pearl-Sallie Lakes area, west-central Minnesota
S. P. Larson, Mark S. McBride, R. J. Wolf
1975, Water-Resources Investigations Report 75-40
-p^e need for study of lake-ground-water interchange has been accentuated by eutrophication of lakes in the Pearl-Sallie Lakes area of west-central Minnesota. The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at...
Perspective diagrams showing geochemical abundance of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in the Nabesna Quadrangle, Alaska
Sherman P. Marsh
1975, Miscellaneous Field Studies Map 655-G
The seven perspective diagrams on this sheet show the distribution patterns of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in stream sediments in the Nabesna quadrangle. The diagrams portray the distribution and abundance of the elements and their relation to some of the geologic units (Richter, 1975) in easy-to-visualize,...
Basic data for some recent Australian heat-flow measurements
Robert J. Munroe, J.H. Sass, G.T. Milburn, J.C. Jaeger, H.Y. Tammemagi
1975, Open-File Report 75-567
This report has been compiled to provide background information and detailed temperature and thermal conductivity data for the heat-flow values reported in Sass, Jaeger, and Munroe (in press). The data were collected as part of a joint heat-flow study by the Australian National University (ANU) and the U.S. Geological Survey...
Chemical analyses (raw laboratory data) and locality index maps of the Confederate Gulch area, Broadwater and Meagher Counties, Montana
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-212
Analysis of the side looking airborn radar imagery of Massachusetts, Connecticut and Rhode Island indicates that radar shows the topography in great detail. Since bedrock geologic features are frequently expressed in the topography the radar lends itself to geologic interpretation. The radar was studied by comparisons with field mapped geologic...
Lithology and chemical analyses of core and cuttings from USGS drill hole near Gold Acres, Lander County, Nevada
Chester T. Wrucke
1975, Open-File Report 75-363
Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
