Sheeted dikes, gabbro, and pillow basalt in flysch of coastal southern Alaska
Russell G. Tysdal, J. E. Case, G. R. Winkler, S. H. B. Clark
1977, Geology (5) 377-383
A Paleocene to Eocene(?) mafic sequence of igneous rocks on Knight Island and a Cretaceous mafic and ultramafic sequence of the Resurrection Peninsula in coastal southern Alaska are characterized by pillow basalts, sheeted dikes, and gabbro intrusions. At both localities, pillow basalts are interbedded with flysch, and the gabbros intrude...
Mechanical twinning in diopside Ca(Mg,Fe)Si2O6: Structural mechanism and associated crystal defects
Stephen H. Kirby, J.M. Christie
1977, Physics and Chemistry of Minerals (1) 137-163
iopside twins mechanically on two planes, (100) and (001), and the associated macroscopic twinning strains are identical (Raleigh and Talbot, 1967). An analysis based on crystal structural arguments predicts that both twin mechanisms involve shearing of the (100) octahedral layers (containing Ca2+, Mg2+ and Fe2+ ions) by a magnitude of c/2. Small adjustments...
Geology of the Waynesboro East and Waynesboro West Quadrangles, Virginia
Thomas M. Gathright II, William S. Henika, John L. Sullivan
1977, Book, Virginia Division of Mineral Resources Publication
The Waynesboro East and Waynesboro West Quadrangles comprise an area of approximately 117 square miles (304 sq km) in portions of Albemarle, Augusta, and Nelson counties in north-central Virginia. Included in the quadrangles are portions of the Piedmont, Blue Ridge, and Valley and Ridge physiographic provinces and two major regional...
Saline-water intrusion related to well construction in Lee County, Florida
Durward Hoye Boggess, T.M. Missimer, T.H. O’Donnell
1977, Water-Resources Investigations Report 77-33
Ground water is the principle source of water supply in Lee County, Florida where an estimated 30,000 wells have been drilled since 1990. These wells ranges in depth from about 10 to 1,240 feet and tap the water table aquifer or one or more of the artesian water-bearing units or...
Geohydrology of Muscatine Island, Muscatine County, Iowa
R.E. Hansen, W. L. Steinhilber
1977, Water Supply Bulletin 11
Muscatine Island is a wide segment of the west bank of the Mississippi River flood plain that covers about 50 square miles in Muscatine and Louisa Counties; the project area encompasses the 30 square miles in Muscatine County. The flood plain is underlain by thick, permeable alluvial deposits that comprise...
Lakes of Oregon, Volume 5: Marion County
Joseph F. Rinella
1977, Report
An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never...
Tactical approach for determining impact of energy development on wildlife in Wyoming: special report number 1
Kent D. Keenlyne
1977, FWS/OBS 77/42
The U.S. Fish and Wildlife Service, within the Department of Interior, is responsible for providing national leadership in the management and protection of the nation's fish and wildlife resources, their habitat, and environment. Specifically, the Office of Biological Services obtains and assimilates biological and environmental data and identifies additional informational...
Geologic time: The age of the Earth
William L. Newman
1977, Report
The Earth is very old 4 1/2 billion years or more according to recent estimates. This vast span of time, called geologic time by earth scientists and believed by some to reach back to the birth of the Solar System, is difficult if not impossible to comprehend in the familiar...
Natural hazards on the island of Hawaii
D. W. Peterson, D. R. Mullineaux
1977, Report
The island of Hawaii and the other islands of the Hawaiian chain are products of volcanic eruptions. Lava flows from hundreds of thousands of eruptions through countless centuries have built the Hawaiian Islands. Some volcanoes on the island of Hawaii have been very active during historic time, and similar activity...
