A topology of mineralization and its meaning for prospecting
George Joseph Neuerburg
1980, Open-File Report 80-298
Epigenetic mineral deposits are universal members of an orderly spatial-temporal arrangement of igneous rocks, endomorphic rocks, and hydrothermally altered rocks. The association and sequence of these rocks is invariant whereas the metric relations and configurations of the properties of these rocks are unlimited in variety. This characterization satisfies the doctrines...
Ground water in the Piedmont Upland of central Maryland
Claire A. Richardson
1980, Water-Resources Investigations Report 80-18
Aquifers in a 130-square-mile area of the central Maryland and Piedmont, are shown to be the sole or principal source of water. The study area is underlain chiefly by crystalline rocks and partly by unaltered sandstones and siltstones. The groundwater is derived from local precipitation and generally occurs under water-table...
Makah Formation — A deep-marginal-basin sequence of late Eocene and Oligocene age in the northwestern Olympic Peninsula, Washington
P. D. Snavely, A. R. Niem, N. S. MacLeod, J. E. Pearl, W. W. Rau
1980, Professional Paper 1162-B
The Makah Formation of the Twin River Group crops out in a northwest-trending linear belt in the northwesternmost part of the Olympic Peninsula, Wash. This marine sequence consists of 2800 meters of predominantly thin-bedded siltstone and sandstone that encloses six distinctive newly named members--four thick-bedded amalgamated turbidite sandstone members, an...
Chemical analyses of coal from the Dakota and Straight Cliffs formations, southwestern Utah region, Kane and Garfield counties, Utah
Ronald H. Affolter, Joseph R. Hatch
1980, Open-File Report 80-138
As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 26 coal samples were collected from the Cretaceous Dakota and Straight Cliffs Formations, Southwestern Utah Region, Kane and Garfield Counties, Utah. Seven samples are from four core holes in...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Little Laughery Creek, Ripley and Franklin counties, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1980, Open-File Report 80-74
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing Limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Little Laughery Creek tributary and Little Laughery Creek was used to predict alternatives for future waste loadings that would...
Geohydrology of the Delta-Clearwater area, Alaska
Dorothy E. Wilcox
1980, Water-Resources Investigations Report 80-92
The alluvial aquifer in the Delta-Clearwater area, Alaska, is composed of lenticular, interbedded deposits of silt, sand, and gravel. Ground water occurs under both confined and unconfined conditions in the area. The potentiometric surface slopes approximately northward at gradients ranging from about 1 to 25 feet per mile. The aquifer...
