Geology of the central and northern parts of the Western Cascade Range in Oregon
Dallas L. Peck, Allan B. Griggs, Herbert G. Schlicker, Francis G. Wells, Hollis M. Dole
1964, Professional Paper 449
This report pt·esents a description of the stratigraphy, structure, and petrology of the volcanic rocks of the central and northern parts of the Western Cascade Range of Oregon. The study is a part of a long-range cooperative program between the U.S. Geological Survey and the Oregon State Department of Geology...
Cambrian rocks of the Pioche mining district, Nevada: With a section on Pioche shale faunules
Charles Warren Merriam, Allison R. Palmer
1964, Professional Paper 469
The Pioche mining district in the Ely Range, southeastern Nevada, is one of several districts in the Great Basin where Cambrian rocks are hosts of important ore deposits. Cambrian strata underlying the Ely Range are intruded by porphyritic granite and other dikes. Tertiary volcanic rocks and Pliocene fresh-water clastic deposits...
Preliminary report on tests of the application of geophysical methods to Arctic ground water problems
David F. Barnes, Gerald R. MacCarthy
1964, Open-File Report 64-9
Seismic refraction and electrical resistivity surveys were made during the summer and fall of 1952 in the Tanana Valley near Fairbanks, Alaska, as part of the studies of the application of geophysical techniques to ground-water problems in Alaska instigated in 1951 by the U.S. Army Engineer Research and Development Laboratories....
Foraminifera from the Northern Olympic Peninsula, Washington
Weldon W. Rau
1964, Professional Paper 374-G
Foraminifera from a Tertiary sequence that crops out on the northern part of the Olympic Peninsula, Wash., show stratigraphic and ecologic significance. Forty-two species that are important both to correlations and to ecologic interpretations are illustrated and systematically discussed. The Foraminifera indicate that some of the rocks may be as...
Giant Upper Cretaceous oysters from the Gulf coast and Caribbean
Norman F. Sohl, Erle G. Kauffman
1964, Professional Paper 483-H
Two unusually massive ostreid species, representing the largest and youngest Mesozoic members of their respective lineages, occur in Upper Cretaceous sediment of the gulf coast and Caribbean areas. Their characteristics and significance, as well as the morphologic terminology of ostreids in general, are discussed. Crassostrea cusseta Sohl and Kauffman n. sp....
Geology of the Guadalupe Mountains, New Mexico
Philip Thayer Hayes
1964, Professional Paper 446
After the discovery of oil in Permian rocks in Winkler County, Tex., in 1920, petroleum exploration intensified in adjacent parts of western Texas and southeastern New Mexico. Almost immediately unusual stratigraphic complexities were discovered in the Permian rocks. Thus began a long period of stratigraphic investigations, chiefly reconnaissance studies, of...
