Galiuro Volcanics, Pinal, Graham, and Cochise counties, Arizona
S.C. Creasey, Medora H. Krieger
1978, Journal of Research of the U.S. Geological Survey (6) 115-131
The Galiuro Volcanics occurs in the Galiuro, Winchester, and Little Dragoon Mountains, east and northeast of Tucson, Ariz. The sequence comprises lava flows and ash-flow tuffs ranging in composition from andesite to rhyolite. In general they can be subdivided into two parts separated by a major erosional unconformity. The lower...
Implications of the petrochemistry of palladium at Iron Canyon, Lander County, Nevada
Norman J. Page, Ted G. Theodore
1978, Journal of Research of the U.S. Geological Survey (6) 107-114
Approximately one-half of the 270 samples from the Iron Canyon area, Nevada, analyzed for platinum-group metals, contain measurable amounts of palladium in the 0.001- to 0.02-part per million range with an average of 0.0034 ppm. The rocks include lower Paleozoic sedimentary and volcanic rocks, Tertiary granitic porphyries, and breccia, all...

Igneous and metamorphic petrology of the southwestern Dana Mountains, Lassiter Coast, Antarctic Peninsula
Walter R. Vennum
1978, Journal of Research of the U.S. Geological Survey (6) 95-106
The southwestern Dana Mountains of the southern Antarctic Peninsula are underlain by the western part of a composite concentrically zoned Upper Cretaceous batholith consisting largely of granodiorite. The granodiorite (felsic phase) was intrusive into older heterogeneous gabbro-diorite (mafic phase) which makes up the margin of the batholith. Flat-lying pegmatite bodies...
Petrology of the Precambrian intrusive center at Lake George, southern Front Range, Colorado
R. A. Wobus, R. S. Anderson
1978, Journal of Research of the U.S. Geological Survey (6) 81-94
The intrusive center at Lake George, at the western margin of the Pikes Peak batholith (1030 m.y.) of central Colorado, contains rocks of both the potassic and sodic differentiation trends recognized in the batholith. Finer grained variants of the Pikes Peak Granite initially formed a texturally zoned stock 8 kilometers...
Metamorphic forsterite and diopside from the ultramafic complex at the Tuolumne River, California
B. A. Morgan
1978, Journal of Research of the U.S. Geological Survey (6) 73-80
Metamorphic forsterite (Fo=98) and diopside (Wo:En:Fs=48.5:49.5:2.0) have been, formed from serpentinite within intensely sheared zones in the large ultramafic complex at the Tuolumne River near Sonora, Calif. Bladelike grains of forsterite are elongate, parallel to c, and have prominent idiomorphic faces developed in (010). Metamorphic diopside occurs as small grains,...
Potential applications of satellite imagery in some types of natural resource inventories
Wayne G. Rohde
H. Gyde Lund, Vernon J. LaBau, Peter F. Ffolliott, David W. Robinson, editor(s)
1978, Conference Paper, Integrated inventories of renewable natural resources: Proceedings of the workshop
Landsat satellite imagery has been routinely available to researchers and resource scientists since 1972. Many studies have demonstrated the application of Landsat imagery for conducting inventories and mapping various natural resources. Examples of applications presented in this paper include: timber volumeinventory, range productivity inventory, wildland vegetation mapping, inventory of rangeland...
Porphyry copper exploration model for northern Sonora, Mexico
Gary L. Raines
1978, Journal of Research of the U.S. Geological Survey (6) 51-58
The regional tectonic pattern of the porphyry copper province of northern Sonora, Mexico, is similar to, but more complex than, the Colorado mineral belt. Four northeast-trending shear zones, spaced at 30- to 50-kilometer intervals from Hermosillo, Mexico, north to Nogales, Mexico, are interpreted from analysis of lineament data from Landsat-1...
Hypothesis: Many earthquakes in the central and southeastern United States are causally related to mafic intrusive bodies
F. A. McKeown
1978, Journal of Research of the U.S. Geological Survey (6) 41-50
Assessment of earthquake hazards in the United States is based largely upon knowledge acquired in the seismically active parts of the western United States. Earthquakes in the central and southeastern United States are seismologically and geologically very anomalous, however, compared with those in the western United States. For example, shallow...
Accuracy and consistency comparisons of land use and land cover maps made from high-altitude photographs and Landsat multispectral imagery
Katherine Fitzpatrick-Lins
1978, Journal of Research of the U.S. Geological Survey (6) 23-40
Accuracy analyses for land use and land cover maps of the 74712-km2 Central Atlantic Regional Ecological Test Site were performed for a 1-percent sample of the area. Researchers compared Level II land use and land cover maps produced at three scales, 1:24000, 1:100000, and 1:250000 from high-altitude photographs, with point...
Determination of runoff coefficients of storm-water-basin drainage areas on Long Island, New York, by using maximum-stage gages
D. A. Aronson
1978, Journal of Research of the U.S. Geological Survey (6) 11-21
A method for determining runoff coefficients indirectly without direct measurement of volume of runoff was developed for drainage areas of selected storm-water basins on Long Island, N.Y., to expedite evaluation of basin performance. The method requires a maximum-stage gage to record the maximum water level attained in the basin...
Cartographic research 1977
Water Resources Division, U.S. Geological Survey
1978, Report
Two major subjects of the current research of the Topographic Division as reported here are related to policy decisions affecting the National Mapping Program of the Geological Survey. The adoption of a metric mapping policy has resulted in new cartographic products with associated changes in map design that require new...
Hydrochemistry and hydrodynamics of injecting an iron-rich pickling liquor into a dolomitic sandstone: A laboratory study
Stephen E. Ragone, Francis S. Riley, Robert James Dingman
1978, Journal of Research of the U.S. Geological Survey (6) 1-9
Waste pickling liquor containing high concentrations of iron salts was injected into cores of quartzite, sandstone, and dolomite in a laboratory study to determine what effect this procedure might have on the permeability of these rock types. Experiments were performed at field conditions 40°C and 13.8 MPa (megapascals) in a...
Think Metric
Water Resources Division, U.S. Geological Survey
1978, Report
The International System of Units, as the metric system is officially called, provides for a single "language" to describe weights and measures over the world. We in the United States together with the people of Brunei, Burma, and Yemen are the only ones who have not put this convenient system...
