Book Description
Field, petrologic, and geochemical data presented herein constrain the origin of porphyry copper mineralization in the Jurassic Yerington batholith. The batholith, with 58-68% SiO2, Peacock index 56, high K2O (3.0 wt% at 60% SiO2), high strontium (1100 ppm), and low initial strontium isotopic composition (0.7040), is similar to high-K orogenic andesites. Three major units were emplaced, from oldest to youngest: granodiorite, quartz monzonite, and porphyritic quartz monzonite (PQM), including porphyry. They show progressive decrease in volume, increase in depth of roof emplacement (

Book Description
Wright (geology, U. of Georgia) and Shervais (geology, Utah State U.) edit selections from a symposium titled "Ophiolites, Batholiths, and Regional Geology: A Session in Honor of Cliff Hopson" held at the Cordilleran Section Meeting of The Geological Society of America in 2005. With contributions from geologists and earth scientists from throughout the United States, the title contains separate sections for papers on the topics of ophiolites, arcs, and batholiths. The publication is illustrated in both black-and-white and color, but contains no index.

Book Description
Scientific analyses of the geology, metallogeny, and mineralization of gold, silver and other high-value elements in the western USATechnical details on working mines, exploration results, new depositsPresentations produced with the United States Geological Survey, Society of Economic GeologistsTwo-volume book set printed in full color with full-text searchable CD-ROM Produced under the auspices of the Geological Society of Nevada and published every five years, this two-volume book of peer-reviewed papers focuses on the geological analysis of ore-rich deposits in the western United States, especially ones containing gold and other high-value elements. Hundreds of stratigraphic, lithographic, remote-sensing and core sample examples are presented, particularly of areas likely to host Carlin-type gold deposits. The two volumes contain a wealth of data on specifically named mines, as well as technical information on high-potential areas for exploration. The book is profusely illustrated with full-color maps, photographs and charts for geology and mining engineering. A searchable CD accompanies the book and includes the full text of papers from the printed book, as well as abstracts and information from poster sessions not found in the printed book. Chapters in the text are fully refereed versions of presentations originally delivered at a symposium supported by the Geological Society of Nevada, along with the United States Geological Survey, Society of Economic Geologists and the Nevada Bureau of Mines. Sample key words: metallogeny, gold, epithermal ore, magmatism, Carlin trend, square array void mapping (SAVM), porphyry copper, tungsten, orogeny, lithogeochemistry, 3-D resistivity and modeling, fault-surface mapping, airborne electromagnetics and more. *The CD-ROM displays figures and illustrations in articles in full color along with a title screen and main menu screen. Each user can link to all papers from the Table of Contents and Author Index and also link to papers and front matter by using the global bookmarks which allow navigation of the entire CD-ROM from every article. Search features on the CD-ROM can be by full text including all key words, article title, author name, and session title. The CD-ROM has Autorun feature for Windows 2000 or higher products and can also be used with Macintosh computers. The CD includes the program for Adobe Acrobat Reader with Search 11.0. One year of technical support is included with your purchase of this product.
