Alteration and mineralization of the northern half of the Aurora mining district, Mineral County, Nevada
(University of Nevada, Reno, 1985)
Alteration and mineralization of the Aurora Mining District has been studied. Epithermal precious metal mineralization of the district is confined to 10.3 m. y. old quartz adularia veins in altered andesite. Alteration ...
Mineralization, alteration, and fluid inclusion studies of the Camas and Princess Blue-Ribbon mines in the Hailey gold belt, Camas and Blaine Counties, Idaho
(University of Nevada, Reno, 1991)
Mineralization, alteration, and fluid inclusions were studied at the Camas and Princess Blue-Ribbon mines.
Geology of the eastern portion of the Indian Wells Canyon mining district, Kern County, California
(University of Nevada, Reno, 1981)
Metamorphic and metasomatic alteration of fine grained Mesozoic carbonate sediments by a late Cretaceous granodiorite has produced a series of small calc-silicate skarns, most containing tungsten mineralization, in the ...
The geology of the Klondike mining district, Esmeralda County, Nevada
(University of Nevada, Reno, 1969)
The geology of the Klondike mining district has been studied and is described in this thesis.
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.
Petrography, alteration, and mineralization of igneous dikes of the Jerritt Canyon District, Elko County, Nevada
(University of Nevada, Reno, 1994)
The petrography, alteration, and mineralization of igneous dikes of the Jerritt Canyon District have been studied. Four types of igneous dikes intrude the sedimentary rocks and two are locally gold ore. The oldest and most ...
The geology and mineralization of the Grayback Mountains, Yavapai County, Arizona
(University of Nevada, Reno, 1992)
The geology and mineralization of the Grayback Mountains were studied. Extrusive and intrusive rocks exposed in the study area document magmatic activity and evolution from the late Cretaceous through the early Tertiary. ...
Geological investigation and ore reserve estimation of the Copper Chief (Ruby Hill) mine, Douglas County, Nevada
(University of Nevada, Reno, 1977)
The geology of the Copper Chief Mine was studied and the ore reserves were estimated. Copper mineralization occurs mainly in the middle two members of the Veta Grande Formation. Ore reserve estimations indicate that 5279 ...
Porphyry-type gold mineralization of late Neogene age at the Zule volcanic center, Sierra County, California
(University of Nevada, Reno, 1992)
The volcanic setting, alteration, geochemical characteristics, and association of gold with quartz stockwork, hydrogene iron oxides, and hypersaline fluid inclusions suggest this is a shallowly-exposed porphyry gold system.
Paragenetic and fluid-inclusion study of Pb-Zn-Ag mineralization at Mina Teresita, Huachocolpa district, Peru
(University of Nevada, Reno, 1983)
This study describes the mineralization process at Mina Teresita and estimates the most probable depth of mineralization.
