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...
Geology and coal deposits of Jarvis Creek coalfield, Alaska
Clyde Wahrhaftig, C.A. Hickcox
1953, Open-File Report 53-263
The Jarvis Creek coal field lies on the north side of the Alaska Range between latitudes 63°35' and 63°45 N., and longitudes 145°40' and 145°50 W. It is 2 to 6 miles east of the Richardson Highway. The coal field is about 16 square miles in area, the major part...
Measurement of earth pressure in the iron-ore mines of eastern France
M.E. Tincelin
1953, Open-File Report 54-30
The purpose of the tests, which will be reported later, is to measure as precisely as possible the tangential stresses exerted on the periphery of a gallery cut in the Lorraine iron ore. The values of the tangential stresses along the periphery being known, they will be compared with the values...
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...
Marine geology of the Near Islands Shelf, Alaska
Philip Challacombe Scruton
1953, Open-File Report 53-245
During the summer of 1950 on the insular shelf surrounding the Near Islands, Alaska, 193 oceanographic stations were occupied from aboard the U. S. Geological Survey vessel EIDER. Bottom character and temperature observations were made at these stations. The composition and size distribution characteristics of the bottom samples have been...
Potential industrial sites in the Lynn Canal area, Alaska
Arthur Johnson, William Stephens Twenhofel
1953, Circular 280
Full development of a proposal to divert the headwaters of the Yukon River drainage from Canada into the Taiya River valley of Alaska would make available more than a half million kilowatts of electrical energy. Utilization of this block of power, for which there is at present no local market,...
Yellow Canary uranium deposits, Daggett County, Utah
Verl Richard Wilmarth
1953, Circular 312
The Yellow Canary uranium deposit is on the west side of Red Creek Canyon in the northern part of the Uinta Mountains, Daggett County, Utah. Two claims have been developed by means of an adit, three opencuts, and several hundred feet of bulldozer trenches. No uranium ore has been produced...
Reconnaissance for radioactive deposits in the lower Yukon-Kuskokwim Highlands region, Alaska
M.G. White, P.L. Killeen
1953, Circular 255
Investigations in 1947 in the Lower Yukon-Kuskokwim region, Alaska found that previously reported radioactivity in the vicinity of Flat is due to uraniferous zircon, an accessory mineral in monzonite. The monzonite intrudes mafic igneous and Upper Cretaceous sedimentary rocks. The maximum equivalent-uranium content of the zircon is 0.14 percent, and...
