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...

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...

N.L. Carter, S. H. Kirby
1978, Pure and Applied Geophysics PAGEOPH (116) 807-839
We review transient creep and semibrittle behavior of crystalline solids. The results are expected to be pertinent to crystalline rocks undergoing deformation in the depth range 5 to 20 km, corresponding to depths of focus of many major earthquakes. Transient creep data for crystalline rocks at elevated temperatures are analyzed...
Mars, highlands-lowlands: Viking contributions to mariner relative age studies
D. H. Scott
1978, Icarus (34) 479-485
Stratigraphic relations between lowland plains and highlands, two major types of Martian geologic-terrain units, were not directly distinguishable on Mariner-9 images. Morphologic characteristics and crater densities suggested that the lava plains beneath their eolian cover were younger than adjacent highland rocks, which form a plateau bounded in many places by...
Lithium in the McDermitt caldera, Nevada and Oregon
