Geology, alteration, and mineralization in the pyroclastic and sedimentary deposits of the Bretz-Aurora Basin, McDermitt Caldera, Nevada-Oregon
(University of Nevada, Reno, 1981)
Miocene to Pliocene age sediments in the Bretz-Aurora basin, 16 miles west of McDermitt, Nevada, form as a series of blanketing phreatomagmatic and plinian, ash and lapilli, subaerial and subaqueous deposits. Epithermal ...
Uniaxial test and mechanical behavior analysis of the tuffaceous beds of Calico Hills, Yucca Mountain, Nevada
(University of Nevada, Reno, 1993)
Uniaxial compression tests were performed on specimens of the tuff found in the Calico Hills near Yucca Mountain. The mechanical properties of the tuffs from the same stratigraphic location are highly consistent and vary ...
Geology of the Buckskin mine, Douglas County, Nevada
(University of Nevada, Reno, 1987)
The Buckskin Mine, developed on a quartz-chlorite-sulfide-gold vein, is hosted by altered meta-andesite and rhyolite porphyry. The vein may have formed in Late Cretaceous time.
Geology of the Lantern property near Scossa mining district, Pershing County, Nevada
(University of Nevada, Reno, 1985)
The Lantern property and Scossa mining district o-f northern Pershing County, Nevada, exhibit gold-silver mineralization characteristic o-f epithermal systems. Mineralized boulders deposited as clasts in a mid-Tertiary ...
The geology and petrography of the Millet Ranch plutons; a mixed magma
(University of Nevada, Reno, 1980)
A combined field and petrographic study of the Millet Ranch Plutons was undertaken in order to describe the spatial, mineralogical and textural variations between and within two granitic plutons.
Lineaments in north-central Nevada and their relations to geothermal areas
(University of Nevada, Reno, 1978)
A lineament map of the Winnemucca Army Map Service sheet was constructed from studies of Skylab photographs, ERTS images, topographic maps and geologic maps. The relations between hot springs and lineaments were then determined.
Geology and hydrothermal alteration of a portion of the eastern Excelsior Mountains, Mineral County, Nevada
(University of Nevada, Reno, 1987)
The eastern Excelsior Mountains are underlain by Permian, Triassic and Cretaceous volcaniclastic sedimentary rocks and porphyry stocks that are unconformably overlain by Tertiary ash-flow tuff, andesite lava flows, and ...
Mesozoic and Cenozoic structural geology of the CP Hills Nevada Test Site, Nye County, Nevada; and regional implications
(University of Nevada, Reno, 1991)
An in-depth study regarding the structural geology of the CP Hills at the Nevada Test site was conducted and the regional implications are discussed.
The geology and mineralization of the Chalk Mountain and Westgate mining districts, Churchill County, Nevada
(University of Nevada, Reno, 1972)
The geologic study of the Chalk Mountain and Westgate mining districts was conducted to identify the lithology and prominent structures in the area.
Geology of a uranium deposit in the Virginia Mountains, Washoe County, Nevada
(University of Nevada, Reno, 1956)
The rocks found in the area of study are mainly Mio-Pliocene welded rhyolite tuffs and are part of the acid and intermediate pyroclastic rocks that cover much of west central Nevada. Uranium minerals have been found in the ...
