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,...
Coal: special report number 2
Kent D. Keenlyne
1977, FWS/OBS 77/43
The Fish and Wildlife Service has extensive biological expertise within the Department of Interior and exerts 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...
Crater clusters and light mantle at the Apollo 17 site: A result of secondary impact from Tycho
Baerbel K. Lucchitta
1977, Icarus (30) 80-96
The morphologies of Tycho secondary craters and their ejecta deposits were studied using full-Moon, Lunar-Orbiter, and Apollo panoramic photographs. These data were compared with similar data for the secondary craters and light mantle of the Apollo 17 landing site. The results indicate that (1) the central crater cluster and the...

Analysis and machine mapping of the distribution of band recoveries
L.M. Cowardin
1977, Special Scientific Report - Wildlife 198
A method of calculating distance and bearing from banding site to recovery location based on the solution of a spherical triangle is presented. X and Y distances on an ordinate grid were applied to computer plotting of recoveries on a map. The advantages and disadvantages of tables of recoveries by...

Some Bayesian statistical techniques useful in estimating frequency and density
Douglas H. Johnson
1977, Special Scientific Report - Wildlife 203
This paper presents some elementary applications of Bayesian statistics to problems faced by wildlife biologists. Bayesian confidence limits for frequency of occurrence are shown to be generally superior to classical confidence limits. Population density can be estimated from frequency data if the species is sparsely distributed relative to the size...
