The swamps, marshes, and open waters of Tsala Apopka Lake, Florida, were mapped and the hydrologic connection between the lake and the Floridan limestone aquifer was studied from October 1975 to September 1976. Tsala Apopka Lake is a series of shallow , interconnected lakes, ponds, and marshes whose water surface...
Geology of the Monterey Bay region
H. Gary Greene
1977, Open-File Report 77-718
Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history. Uplift and depression have produced a succession of regressive and transgressive sedimentary units, while contemporaneous...

1977, Water-Resources Investigations Report 76-123
The Englishtown Formation of the Matawan Group of Late Cretaceous age is exposed in the western part of the New Jeresy Coastal Plain along a northeast-southwest trending zone extending from Raritan Bay to Delaware Bay. In outcrop, in the northern part of the Coastal Plain, the Englishtown typically consists of...

W. P. Irwin, D. L. Jones, E.A. Pessagno Jr.
1977, Geology (5) 557-562
Ribbon cherts and siliceous tuffs of the North Fork and Rattlesnake Creek terranes of the Klamath Mountains yield Mesozoic radiolarians. Rocks of the North Fork terrane were previously considered to be of Paleozoic age and those of the Rattlesnake Creek to be of Paleozoic and Triassic age, on the basis...
Deposition of the Tapeats Sandstone (Cambrian) in central Arizona
Richard Hereford
1977, GSA Bulletin (88) 199-211
Grain size, bedding thickness, dispersion of cross-stratification azimuths, and assemblages of sedimentary structures and trace fossils vary across central Arizona; they form the basis for recognizing six facies (A through F) in the Tapeats Sandstone. Five of these (A through E), present in western central Arizona, are marine deposits containing...
Lower Tertiary biostratigraphy of the northern Santa Lucia Range, California
Richard Z. Poore, William V. Sliter, M. H. Link
1977, Journal of Research of the U.S. Geological Survey (5) 735-745
Lower Tertiary strata in .the northern Santa Lucia Range of California are correlated by means of planktonic and benthonic foraminifers. Benthonic foraminiferal assemblages from eight stratigraphic sections range in age from Ynezian to possible basal Refugian. The Paleocene mudstone contains a Ynezian benthonic foraminiferal assemblage. The Ulatisian benthonic assemblage of...

R. A. Loney, Glen R. Himmelberg
1977, Journal of Research of the U.S. Geological Survey (5) 761-781
The terrane bordering the alpine-type Josephine Peridotite on the north in the Vulcan Peak area, southwestern Oregon, is composed of intrusive hornblende gabbro (Middle Jurassic) and scattered remnants of clinopyroxene-bearing ultramafic rocks and amphibolite. The amphibolite, which preliminary analyses suggest is of andesitic composition, has undergone regional metamorphism to the...

R.E. Miller
1977, Journal of Research of the U.S. Geological Survey (5) 497-509
A steady-state simulation model was applied to the shallow hydrothermal system in the East Mesa area of Imperial Valley, Calif. The steady-state equations of flow and heat transport were solved by use of a Galerkin, finite-element method. A solution was obtained by iterating between the temperature and pressure equations, using...

K.F. Higgins
1977, Journal of Wildlife Management (41) 232-242
A study to determine the major factors limiting duck nesting and production on intensively farmed areas in eastern North Dakota was conducted from 1969 through 1974. A total of 186 duck nests was found during searches on 6,018 ha of upland. Nest density per km2 for 5 major habitat types...
Geology and water-supply potential of the Anoka Sand Plain aquifer, Minnesota
J. O. Helgesen, G. F. Lindholm
1977, Technical Paper 6
Intensified land development on the Anoka sand plain necessitates a better understanding of the hydrogeology of the surficial outwash deposits of the area. The Anoka sand-plain aquifer consists of outwash attributable to two different ice lobes. Predominant grain size of the upper outwash decreases and sorting coefficient increases from west...

John R. Donnell, Van E. Shaw
1977, Journal of Research of the U.S. Geological Survey (5) 221-226
Mercury has been reported in concentrations as high as 4 parts per million from oil shale in the Green River Formation near the Federal oil-shale prototype lease-tracts U-a and U-b in eastern Utah. This high concentration of mercury if present throughout a minable zone, would be of concern in commercial...
