Bright Angel and Mesa Butte fault systems of northern Arizona
Eugene Merle Shoemaker, R. L. Squires, M. J. Abrams
Robert B. Smith, Gordon P. Eaton, editor(s)
1978, Book chapter, Cenozoic tectonics and regional geophysics of the western Cordillera
Regional geologic mapping using pictures from the first Earth Resources Technology Satellite (ERTS-1) has led to the recognition of two parallel northeast-trending systems of normal faults, each of which can be traced more than 100 km. Many eruptive centers appear to be localized along these fault systems or along their...

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...
