Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 122. This excursion will present an overview of the stratigraphy, structure, and tectonic evolution of the margin of early Mesozoic North America in the Great Basin and of terranes tectonically accreted above and against this margin. Exposures to be visited will show the following features: 1) the Golconda allochthon, a tract of oceanic Paleozoic rocks that was thrust some 100 km across the edge of Triassic North America; 2) shelfal and platformal lower Mesozoic strata that unconformably cover the Golconda allochthon; 3) basinal lower Mesozoic strata that accumulated seaward of the inherited continental edge; 4) Mesozoic and Paleozoic arc volcanics; and 5) Jurassic and Cretaceous foreland structures developed in all the preceding rocks after accretion of terranes had left the early Mesozoic sialic margin well inboard of the active convergent margin. This guide begins with introductions to the neotectonic and Phanerozoic paleotectonic evolutions of the Great Basin. Thereafter, its contents are organized in sequence with field trip stops which are as follows [route map in Figs. 5 and 6]: Day 1. Battle Mt. Golconda allochthon. Day 2. Tobin, Stillwater, and southern Humboldt Ranges. Stratigraphy of platform to basin transition of Triassic cover, Jurassic foreland thrusting; 1915 Pleasant Valley earthquake scarp. Day 3. Sand Springs and Paradise Ranges. Terranes of volcanogenic Triassic and Paleozoic rocks structurally outboard of parautochthonous lower Mesozoic basinal and shelf edge rocks. Days 4 and 5. Mina and Candelaria. North-south traverse across structurally condensed Early Triassic collision zone of exotic Paleozoic arc, Golconda allochthon plus serpentinite melange, Golconda foreland basin strata on Early Triassic North America; these units were covered by Middle and Upper Triassic strata and imbricated with the cover in late Mesozoic foreland thrusting. Day 6. Yerington. Stratigraphy and structure of possibly oldest continental magmatic arc rocks in western Great Basin.

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.

Through a remarkable combination of intellect, self-confidence, engaging humility, and prodigious output of published work, William R. Dickinson influenced and challenged three generations of sedimentary geologists, igneous petrologists, tectonicists, sandstone petrologists, archaeologists, and other geoscientists. A key figure in the plate-tectonic revolution of the 1960s and 1970s, he explained how the distribution of sediments on Earth's surface could be traced to tectonic processes, and is widely recognized as a founder of modern sedimentary basin analysis. This volume consists of 31 chapters related to Dickinson's research interests; many of the authors are his former students, their students, and their students' students, demonstrating his continuing profound influence. The papers in this volume are an impressive tribute to the depth and breadth of Bill Dickinson's contributions to the geosciences.

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.
