Book Synopsis The Tectonic Setting and Origin of Cretaceous Batholiths within the North American Cordillera by : Robert S. Hildebrand
Download or read book The Tectonic Setting and Origin of Cretaceous Batholiths within the North American Cordillera written by Robert S. Hildebrand. This book was released on 2017-10-03. Available in PDF, EPUB and Kindle. Book excerpt: In this Special Paper, Hildebrand and Whalen present a big-picture, paradigm-busting synthesis that examines the tectonic setting, temporal relations, and geochemistry of many plutons within Cretaceous batholithic terranes of the North American Cordillera. In addition to their compelling tectonic synthesis, they argue that most of the batholiths are not products of arc magmatism as commonly believed, but instead were formed by slab failure during and after collision. They show that slab window and Precambrian TTG suites share many geochemical similarities with Cretaceous slab failure rocks. Geochemical and isotopic data indicate that the slab failure magmas were derived dominantly from the mantle and thus have been one of the largest contributors to growth of continental crust. The authors also note that slab failure plutons emplaced into the epizone are commonly associated with Cu-Au porphyries, as well as Li-Cs-Ta pegmatites.

Book Synopsis Andean Tectonics by : Brian K. Horton
Download or read book Andean Tectonics written by Brian K. Horton. This book was released on 2019-06. Available in PDF, EPUB and Kindle. Book excerpt: Andean Tectonics addresses the geological evolution of the Andes Mountains, the prime global example of subduction-related mountain building. The Andes forms one of the most extensive mountain belts on Earth, spanning approximately an 8,000 km distance along the western edge of South America, from 10°N to 55°S. The tectonic history of the Andes involves a rich record of diverse geological processes, including crustal deformation, magmatism, sedimentary basin evolution, and climatic interactions. This book addresses the range of Andean tectonic processes and their temporal and spatial variations. This critical resource is ideal for researchers interested in the causes and consequences of Andean-type orogenesis and the long-term evolution of fold-thrust belts, magmatic arcs, and forearc and foreland basins. Evaluates the history of Andean mountain building over the past 250 million years (the Mesozoic and Cenozoic eras) Integrates recent results and provides new perspectives on the complementary records of deformation, magmatism and sedimentary basin evolution, along with their interactions in time and space Provides insights into the development of the northern, central and southern Andes, all of which have typically been considered in isolation

Book Synopsis Evolution of an Andean Margin by : Suzanne Mahlburg Kay
Download or read book Evolution of an Andean Margin written by Suzanne Mahlburg Kay. This book was released on 2006-01-01. Available in PDF, EPUB and Kindle. Book excerpt: "The objective of this volume is to examine the Cenozoic tectonic and magmatic evolution from the arc to the retroarc of a distinctive end-member of the Andean accretionary orogen between 35*S and 39*S. The evolution of the Andes in this region provides an outstanding case study of an orogen where periods of contraction and extension, crustal shortening and normal faulting, and differences in retroarc volcanism reflect a tectonic regime that alternates in space and time. Structural, magmatic, and paleogeographic patterns correlate strongly with the dynamics of the subduction zone. The region includes the Neuquen basin which is one of the most prolific of the Central Andes. The tectonic setting is important in understanding hydrocarbon systems of the sub-Andean basin and the potential for ore deposits in the cordillera. The book is fundamental for researchers working on tectonics and magmatism in Andean type systems as well as those involved in exploration."--Publisher's website.

Book Synopsis The Geology of Chile by : Teresa Moreno (Ph. D.)
Download or read book The Geology of Chile written by Teresa Moreno (Ph. D.). This book was released on 2007. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive account in English of the geology of Chile, providing a key reference work that brings together many years of research, and written mostly by Chilean authors from various universities and other centres of research excellence. The 13 chapters begin with a general overview, followed by detailed accounts of Andean tectonostratigraphy and magmatism, the amazingly active volcanism, the world class ore deposits that have proven to be so critical to the welfare of the country, and Chilean water resources. The subject then turns to geophysics with an examination of neotectonics and earthquakes, the hazardous frequency of which is a daily fact of life for the Chilean population. There are chapters on the offshore geology and oceanography of the SE Pacific Ocean, subjects that continue to attract much research not least from those seeking to understand world climatic variations, and on late Quaternary land environments, concluding with an account examining human colonization of southernmost America. The geological evolution of Chile is the c. 550 million year history of a continental margin over 4000 km long. During his voyage on H.M.S. Beagle, an extended visit to Chile (1834-35) had a profound impact on Charles Darwin, especially on his understanding of volcanoes, earthquakes and tsunamis.
