P.F. Watson, editor(s)
1978, Book chapter, Artificial Breeding of Non-Domestic Animals.
Captive breeding of non-domestic birds has increased dramatically in this century, and production of young often exceeds that of the same number of birds in their native habitat. However, when infertility is a problem, artificial insemination can be a useful method to improve production. Artificial insemination programs with non-domestic birds...
Significance of age relations above and below upper jurassic ophiolite in the Geysers-Clear Lake region, California
R. J. McLaughlin, E.A. Pessagno Jr.
1978, Journal of Research of the U.S. Geological Survey (6) 715-726
In The Geysers-Clear Lake area of northern California, a fragmented Upper Jurassic ophiolite overlain depositionally by the Great Valley sequence is juxtaposed over deformed and metomorphosed rocks of the Franciscan assemblage along the Coast Range thrust. The basal strata of the Great Valley sequence consist of thick breccias of mafic...
A reexamination of the Pennsylvanian trace fossil Olivellites
Ellis L. Yochelson, David E. Schindel
1978, Journal of Research of the U.S. Geological Survey (6) 789-796
The original interpretation of Olivellites plummeri Fenton and Fenton as the trace of an infaunal gastropod, is reconsidered and rejected. The original slab bearing several examples of O. plummeri has been reexamined and reillustrated. The slab came from the type-locality of O. plummeri in Eastland County, Tex., and is a shallow...
Upper Devonian radiolarians separated from chert of the Ford Lake Shale, Alaska
Brian K. Holdsworth, D. L. Jones, C. Allison
1978, Journal of Research of the U.S. Geological Survey (6) 775-788
Leaching of black bedded chert from the Ford Lake Shale, Kandik Basin, Alaska, with dilute hydrofluoric acid resulted in the complete separation of moderately well preserved radiolarians. Preliminary study of an assemblage obtained from the lower half of the formation revealed six to eight forms apparently identical to specimens previously...
Solubility of highly soluble salts in aqueous media - Part 1, NaCl, KCl, CaCl2, Na2SO4, and K2SO4 solubilities to 100°C

1978, Journal of Research of the U.S. Geological Survey (6) 701-705
A modified visual method for determining the solubility of highly soluble salts in aqueous media up to 100° C is presented. The solubilities of NaCl, KCl, CaCl2, Na2SO4, and K2SO4 were determined up to 100° C. The tabulated experimental data and the fitted equations describing the data indicate that the...
Application of four input-output models for nutrients in Lake Okeechobee, Florida
Ronald L. Miller
1978, Journal of Research of the U.S. Geological Survey (6) 821-828
R. A. Vollenweider's (1975) nonconservative model described concentrations of nitrogen and phosphorus for 1969-70 in Lake Okeechobee, Fla., better than the models of F. Biffi in 1963, R. H. Rainey in 1967, and R. Piontelli and V. Tonolli in 1964. Vollenweider's model predicted concentrations of 1.4 milligrams per liter of...
Conductive heat flows in research drill holes in thermal areas of Yellowstone National Park, Wyoming
Donald E. White
1978, Journal of Research of the U.S. Geological Survey (6) 765-774
In convection systems with boiling springs, geysers, fumaroles, and other thermal features, the modes of heat flow become increasingly complex as a single liquid phase at depth rises into the near-surface environment where heat flows by convection of liquid and vapor and by conduction in high thermal gradients. This paper...
The geochemical nature of the Archean Ancient Gneiss Complex and Granodiorite Suite, Swaziland: A preliminary study
D.R. Hunter, F. Barker, Hugh T. Millard Jr.
1978, Precambrian Research (7) 105-127
The Ancient Gneiss Complex (AGC) of Swaziland, an Archean gray gneiss complex, lies southeast and south of the Barberton greenstone belt and includes the most structurally complex and highly metamorphosed portions of the eastern Kaapvaal craton. The AGC is not precisely dated but apparently is older than 3.4 Ga. The...
A sediment-dispersal model for the South Texas continental shelf, northwest Gulf of Mexico
G. L. Shideler
1978, Marine Geology (26) 289-313
Textural-distribution patterns of sea-floor sediments on the South Texas continental shelf between Matagorda Bay and the U.S.-Mexico international boundary were evaluated as part of a regional environmental-studies program. Sediment textural gradients support a conceptual model for the regional sediment-dispersal system, which is characterized by both net offshore transport and net...
Distribution and character of upper Mesozoic subduction complexes along the west coast of North America
D. L. Jones, M.C. Blake Jr., E. H. Bailey, R. J. McLaughlin
1978, Tectonophysics (47) 207-222
Structurally complex sequences of sedimentary, volcanic, and intrusive igneous rocks characterize a nearly continuous narrow band along the Pacific coast of North America from Baja California, Mexico to southern Alaska. They occur in two modes: (1) as complexly folded but coherent sequences of graywacke and argillite that locally exhibit blueschist-grade...
Arctic continental shelf morphology related to sea-ice zonation, Beaufort Sea, Alaska

1978, Marine Geology (28) 179-210
Landsat-1 and NOAA satellite imagery for the winter 1972–1973, and a variety of ice and sea-floor data were used to study sea-ice zonation and dynamics and their relation to bottom morphology and geology on the Beaufort Sea continental shelf of arctic Alaska.In early winter the location of the boundary between...

Timothy Wyant
1978, Open-File Report 78-334
An oil spill risk analysis was conducted to determine the relative envionmental hazards of developing oil in different regions of the Eastern Gulf of Mexico Outer Continental Shelf lease area. The study analyzed the probability of spill occurrence, likely paths of the spills, and locations in space and time of...
A simple-harmonic model for depicting the annual cycle of seasonal temperatures of streams
Timothy Doak Steele
1978, Open-File Report 78-155
Due to economic or operational constraints, stream-temperature records cannot always be collected at all sites where information is desired or at frequencies dictated by continuous or near-continuous surveillance requirements. For streams where only periodic measurements are made during the year, and that are not appreciably affected by regulation or by...

Richard I. Grauch
1978, Open-File Report 78-949
Uraninite of Precambrian age occurs locally in and around a massive sulfide deposit at Camp Smith, Westchester and Putnam Counties, New York. The host rocks are believed to be part of a sequence of marine sediments and submarine volcanogenic rocks that were metamorphosed to leucogneisses, amphibolites, and amphoholite gneisses in...

R.H. Simmons, D.H. Carpenter
1978, Water-Resources Investigations Report 78-93
A flood-estimating method is presented which applies to drainage basins in Delaware without urban development and covers selected recurrence intervals from 2 to 100 years. The method was developed by multiple-regression techniques. The State is divided into two regions and sets of equations for calculating peak discharges based on physical...

Ronald Wayne Kistler, Zell E. Peterman
1978, Professional Paper 1071
Initial 87Sr/ 86 Sr was determined for samples of Mesozoic granitic rocks in the vicinity of the Garlock fault zone in California. These data along with similar data from the Sierra Nevada and along the San Andreas fault system permit a reconstruction of basement rocks offset by the Cenozoic lateral...
