Download or read book Trace Elements in Igneous Petrology written by C.J. Allègre and published by Elsevier. This book was released on 2013-10-22 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Igneous Petrology, 5: Developments in Petrology: A Volume in Memory of Paul W. Gast focuses on the contributions and influence of Gast in petrology, including crystallization, magmatic processes, isotopic composition, and ocean ridge basalt chemistry. The selection first takes a look at quantitative models of trace element behavior in magmatic processes; application of trace elements to the petrogenesis of igneous rocks of granitic composition; and an assessment of local and regional isotopic equilibrium in the mantle. Discussions focus on evidence derived from time constraints, scale of isotopic disequilibrium, fractional crystallization, trace element modeling, geodynamics and tectonic setting, partition coefficients, quantitative models for trace elements, and parameter determination and inverse-problem solution. The publication then examines the isotopic composition of lead in oceanic basalt and its implication to mantle evolution; strontium isotopes in basalts from the Pacific Ocean basin; and trace elements in ocean ridge basalts. Concerns cover variations in ocean ridge basalt chemistry, trace elements in ocean ridge basalts, disequilibrium partial melting, seawater alteration, background for lead isotope tracer studies, and uranium, thorium, and lead concentrations in basalts. The book examines trace elements and anorthosite genesis, lead isotopes in Archaean plutonic rocks, early Archaean rocks and geochemical evolution of the earth's crust, and factors controlling the noble gas abundance patterns of deep-sea basalts. The selection is a valuable source of data for researchers interested in petrology.

This book was released on 2013-01-01 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this well-illustrated book, Hildebrand expands upon his model for the development of the North American Cordillera detailed in Special paper 457. Starting with an overview of Cordilleran geology he goes on to provide an in depth look at how the Rubian ribbon continent was assembled. He integrates the complex geology of the Cordillera into an actualistic model involving arc magmatism, arc-continent collision, slab failure magmatism, and transcurrent motion in both Rubia and the western North American margin. While much of the focus is on the assembly of the Rubian ribbon continent, Hildebrand explores its interactions with North America during the Sevier and Laramide events and concludes that North America was the lower plate in both"--Provided by publisher.

Download or read book Ancient Landscapes of Western North America written by Ronald C. Blakey and published by Springer. This book was released on 2017-10-03 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section

Download or read book The Tectonic Setting and Origin of Cretaceous Batholiths within the North American Cordillera written by Robert S. Hildebrand and published by Geological Society of America. This book was released on 2017-10-03 with total page 123 pages. 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.
