Plant microfossils of the Hazard No. 7 coal, Perry County, Kentucky
Robert M. Kosanke
1965, Open-File Report 65-89
The cooperative mapping program between the Kentucky Geological Survey and the U. S. Geological Survey has yielded a number of interesting and valuable by-products. As a part of the stratigraphic studies involving Carboniferous coal fields, R. M. Kosanke has been involved in a detailed analysis of spore floras from various...
Tectonic deformation, subaqueous slides, and destructive waves associated with the Alaskan March 27, 1964, earthquake: an interim geologic evaluation
George Plafker, L.R. Mayo
1965, Open-File Report 65-124
The great earthquake which struck Alaska on Good Friday, March 27, 1964, caused severe damage to the coast of south-central Alaska mainly through vertical tectonic displacements, subaqueous slides, and destructive waves of diverse origins.Notable changes in land level occurred over an area in excess of 50,000 square miles in a...
Allanites from the Boulder Creek batholith, Colorado
Nelson L. Hickling
1965, Open-File Report 65-70
This study of accessory allanites from the Boulder Creek batholith is an adjunct to the comprehensive petrologic study that batholith by George Phair and David Gottfried of the U.S. Geological Survey....
Gravity survey in southern Cascade Range, California
Thomas R. LaFehr
1965, Open-File Report 65-92
A regional gravity survey in the southern Cascade Range and environs was made during the summers of 1962 and 1963. Twelve hundred gravity stations were established within the area enclosed by lat 41°00'N, lat 42°301N, long 120°00'W, and long 124°00'W. Most of the stations are concentrated in an area overlapping...
Plant and miscellaneous microfossils of the Pierre Shale
Estella B. Leopold, Bernadine D. Tschudy
1965, Open-File Report 65-97
This preliminary report summarizes part of a Survey program to study, in detail, the stratigraphy and paleontology of a nearly complete sequence of Pierre Shale near Redbird, Wyoming. The physical stratigraphy and correlations are being analyzed by James Gill and W. A. Cobban. Various groups of invertebrate fossils are under...
A field method for the determination of silver in soils and rocks
H. M. Nakagawa, H. W. Lakin
1965, Open-File Report 65-182
A rapid, sensitive, and specific field method useful in geochemical exploration has been developed for the determination of silver in geologic materials. In this method the sample is digested with nitric acid and the silver is extracted with triisooctyl thiophosphate (TOTP) in benzene and stripped from the organic phase with...
Density comparison method for the measurement of isotopic variations in prepared waters
Joseph Howard McCarthy Jr., Thomas Seward Lovering, Herbert Williams Lakin
1965, Open-File Report 65-103
The falling-drop method of density determination has been modified so that the densities of a standard and a sample water are compared simultaneously. A constant temperature bath that does not vary more than 0.0001°C and an accurate double micropipet are described. The method has sufficient sensitivity and precision to distinguish...
Geology and ore deposits of the central York Mountains, western Seward Peninsula, Alaska
C.L. Sainsbury
1965, Open-File Report 65-142
In the central York Mountains, carbonate rocks of Lower and Middle Ordovician age and aggregating at least 8,000 feet thick are thrust northward over slate and argillaceous limestone of pre-Ordovician age which were intruded by gabbro in pre-Ordovician time. Normal faults of four distinct systems cut the thrust plates, and...
Hot brines and recent iron deposits in deeps of the Red Sea
A.R. Miller, C.D. Densmore, E.T. Degens, J.C. Hathaway, F.T. Manheim, P.F. McFarlin, R. Pocklington, A. Jokela
1965, Open-File Report 65-180
Sedimentary iron and heavy-metal deposits of undetermined size have been found in the middle of the Red Sea some 2000 meters below the surface of the sea. This discovery has been made from the Research Vessel Atlantis II, which is still at sea engaged in a series of oceanographic investigations which...
Geology of the Romanzof Mountains, Brooks Range, northeastern Alaska
Edward G. Sable
1965, Open-File Report 65-141
This remote 700 square mile area in the Brooks Range is topographically rugged and geologically diverse; it contains a granitic pluton, low-grade metamorphic rocks, sedimentary rocks, and mafic igneous rocks, as well as glacial features.Rocks of sedimentary origin include from oldest to youngest:1.Neruokpuk Formation Middle and Upper Devonian(?), more than...
