Dating and recurrence frequency of prehistoric mudflows near Big Sur, Monterey County, California
Lionel E. Jackson Jr.
1977, Journal of Research of the U.S. Geological Survey (5) 17-32
Botanical evidence based on the dendrochronology and root horizons of redwoods (Sequoia sempervirens) and radiocarbon dating were used to date prehistoric mudflows near Big Sur, Calif. At least three periods of mudflow activity were delineated for the approximate prehistoric period 1370-1800. Two historic periods of mudflow activity have occurred, 1908-10...
Muscle scars of late Paleozoic freshwater ostracodes from West Virginia
I. G. Sohn
1977, Journal of Research of the U.S. Geological Survey (5) 135-141
Different adductor muscle attachment scar patterns of the three ostracode genera Darwinula Brady and Robertson, 1885, Gutschickia Scott, 1944, and Whipplella Holland, 1934, from Pennsylvanian and Permian rocks of 'West Virginia are illustrated for the first time. Gutschickia and Whipplella have been considered as junior synonyms of Carbonita Strand, 1928,...
Radiate shell structures in Paleozoic Myodocopid and Palaeocopid ostracodes are epigenetic
I. G. Sohn
1977, Journal of Research of the U.S. Geological Survey (5) 125-133
The radiate structures in the shell of Paleozoic ostracodes are interpreted to be epigenetic in origin. On the basis of this interpretation, the genus Radiicypridina Bless, 1973, is a junior synonym of Eocypridina Kesling and Ploch, 1960. The type-series of Eocypridina radiata (Jones, Kirkby, and Brady, 1874), from the Coal...
Transverse mixing in the Mobile River, Alabama
William Meyer
1977, Journal of Research of the U.S. Geological Survey (5) 11-16
Transverse dispersion in the Mobile River was measured by (1) ground-based techniques using water samples and a fluorometer and (2) by aerial photography. Magnitude of the transverse mixing coefficient obtained by the two methods was 6.2 feet squared per second (0.58 metre squared per second) and 5.0 feet squared...
Surface deformation in part of the San Jacinto Valley, southern California
Douglas M. Morton
1977, Journal of Research of the U.S. Geological Survey (5) 117-124
Ground fissuring and subsidence occur in a deep alluvium-filled graben between the Casa Loma and San Jacinto faults, San Jacinto Valley, southern California. These processes are attributed chiefly to compaction due to withdrawal of ground water. Subsidence due to compaction is estimated to be a maximum of 3.5 centimetres per...
International training in remote sensing
Donald T. Lauer
1977, Conference Paper, Eighth United Nations Regional Cartographic Conference for Asia and the Far East
The training and assistance programme at the Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, South Dakota (United States of America), is designed to provide for the transfer of remote-sensing technology to land managers and resource specialists, both domestic and foreign. The programme does not emphasize research and development...
Use of infrared imagery in bank-storage studies
T. H. Thompson
1977, Journal of Research of the U.S. Geological Survey (5) 1-10
The use of thermal infrared imagery as a reconnaissance tool to identify bank seepage was investigated at Franklin D. Roosevelt Lake in northeastern Washington. The banks of the lake are generally composed of glacial lacustrine sediments deposited when the Cordilleran ice sheet dammed the Columbia River at least three times...
Chemical variability in the Lakeview Mountains pluton, southern California batholith: A comparison of the methods of correspondence analysis and extended Q-mode factor analysis
A.T. Miesch, Douglas M. Morton
1977, Journal of Research of the U.S. Geological Survey (5) 103-116
An extended method of Q-mode factor analysis that has been described previously offers a number of important advantages over conventional Q-mode factor analysis and correspondence analysis when applied to compositional data. Among these are the ability to compute the compositions, in the original units of the data, represented by the...
Topographic control and accumulation rate of some Holocene coral reefs: south Florida and Dry Tortugas
E.A. Shinn, J.H. Hudson, R. B. Halley, B. H. Lidz
D.L. Taylor, editor(s)
1977, Conference Paper, Proceedings: Third International Coral Reef Symposium
Core drilling and examination of underwater excavation on 6 reef sites in south Florida and Dry Tortugas revealed that underlying topography is the major factor controlling reef morphology. Carbon-14 dating on coral recovered from cores enables calculation of accumulation rates. Accumulation rates were found to range from 0.38 m/1000 years...
Some characteristics of Pele's hair
Wendell A. Duffield, Everett K. Gibson Jr., Grant Heiken
1977, Journal of Research of the U.S. Geological Survey (5) 93-101
Pele's hair is a filamentous variety of brown sideromelane glass that forms during eruption of basaltic lava. Strands of Pele's hair form from droplets of lava that are spun or stretched into filaments during quenching, and others may form as chilled streamers of lava. Common elongate vesicles, sometimes twisted, indicate...
Limestone compaction: an enigma
Eugene A. Shinn, Robert B. Halley, J. Harold Hudson, Barbara H. Lidz
1977, Geology (5) 21-24
Compression of an undisturbed carbonate sediment core under a pressure of 556 kg/cm2 produced a “rock” with sedimentary structures similar to typical ancient fine-grained limestones. Surprisingly, shells, foraminifera, and other fossils were not noticeably crushed, which indicates that absence of crushed fossils in ancient limestones can no longer be considered...
A comparison of some analytical techniques for determining uranium, thorium, and potassium in granitic rocks
John S. Stuckless, Hugh T. Millard Jr., Carl M. Bunker, Ignatius T. Nkomo, John N. Rosholt, Charles A. Bush, Claude Huffman Jr., Ronald L. Keil
1977, Journal of Research of the U.S. Geological Survey (5) 83-91
Geochemical exploration for uranium requires accurate and precise determinations of low-level concentrations. We have used seven different techniques and four different treatments of the fluorometric method to analyze for uranium in granitic rocks. In addition we have used four analytical techniques for thorium and three analytical techniques for potassium,...
