Stratigraphic relations of the Shakopee dolomite and the St. Peter sandstone in southwestern Wisconsin
Arthur Emerson Flint
1953, Open-File Report 53-71
This paper is concerned with the origin and geologic history of the boundary that separates the widespread St. Peter sandstone from the underlying Shakopee dolomite. That international surface is highly undulatory, and most contemporary geologists who have examined it believe that the contact irregularities result from pre-St. Peter subaerial erosion...
Domestic phosphate deposits
V.E. McKelvey, J.B. Cathcart, Z. S. Altschuler, R. W. Swanson, Katherine Lutz
1953, Open-File Report 53-165
Most of the worlds phosphate deposits can be grouped into six types: 1) igneous apatite deposits; 2) marine phosphorites; 3) residual phosphorites; 4) river pebble deposits; 5) phosphatized rock; and 6) guano. The igneous apatites and marine phosphorites form deposits measurable in millions or billions of tons; the residual deposits...
Stratigraphic sections at White Pine copper mine, Ontonagon County, Michigan
Walter S. White, J.C. Wright
1953, Open-File Report 53-269
The lithology and stratigraphy of the ore zones near the base of the Nonesuch formation in the vicinity of the White Pine copper mine, Ontonagon County, Michigan, are shown on preliminary stratigraphic sections that have been made available for examination.Partial logs of 91 holes, drilled by the Copper Range Company...
Results of exploration at the Old Leyden coal mine, Jefferson County, Colorado
A.J. Gude, F. A. McKeown
1953, Open-File Report 53-82
Six diamond core holes totaling 2, 201 feet were drilled by the. U, S. Bureau of Mines under contract to the U. S. Atomic Energy Commission at the Old Leyden coal mine, Jefferson County, Colo. The holes were spotted on the basis of geologic mapping by the U. S. Geological...
The Alberhill and other clay deposits of Temescal Canyon, Riverside County, California
Steven Norman Daviess, M. N. Bramlette
1953, Open-File Report 53-52
Clay is mined in open pits by several companies in the Alberhill district, and the refractory clays of relatively high alumina sediment are used largely for fire brick. The Alberhill Coal and Clay Company is the largest operator and has produced a little over 2,000,000 tons of clay, of which...
Quaternary geology of the Nenana River and adjacent parts of the Alaska Range, Alaska
Clyde Wahrhaftig
1953, Open-File Report 53-262
The Nenana River flows northward across the Alaska Range near 149° west longitude. Sedimentary bedrock formations of its basin include pre-Cambrian schist undifferentiated Paleozoic and Mesozoic rocks, continental upper Cretaceous rocks and poorly consolidated continental Tertiary rocks. Igneous rocks include pre Devonian quartz orthoclase schist, greenstone, granitic and basic intrusives...
Clay deposits of the Tierra Colorado district, southern Orange County, California
Steven Norman Daviess, M. N. Bramlette
1953, Open-File Report 53-51
The clay of this district is being mined for fire brick by the Vitrofrax Corporation. Much of the clay contains 35 percent or more of alumina and between 1 and 2 percent of iron oxide. Production is largely from an underground mine as the best clay deposit known in the...
