Book Synopsis Early Precambrian Basic Magmatism by : R.P. Hall
Download or read book Early Precambrian Basic Magmatism written by R.P. Hall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic magmatic rocks make up approximately three-quarters of the crust ofthe present day Earth. Because we can observe and study the volcanic products of present day tectonic regimes comprehensively, we can shed light on ancient tectono-magmatic provinces, and thereby deduce the petrogenesis and evolution of the oldest basic rocks. This is the primary objective of this book. The book was conceived in order to provide a comprehensive review of the basic rocks produced during the first half of the Precambrian, i.e. the Archaean and early Proterozoic, to about 1.8 Ga years ago. Two major questions are addressed. First, what basic magmas were generated during the early Precambrian: were these magmas globally uniform, and to what extent were prevailing tectonic controls and compo sitions analogous to those of the present day? Clearly, this can be answered only by bringing together fundamental information about all relevant basic magmatic events. Second, is there any systematic temporal variation in the nature of basic suites, and what implications might such variations have on our interpretations of early Earth history? Are there important differences between early Archaean, late Archaean, Proterozoic and modern basic magmatic suites? The book uses two approaches to address these questions. Early chapters examine the fundamental characteristics of these basic rocks, whilst later chapters assess regional distribution and development by providing an overview of each major early Precambrian craton.
Book Synopsis Proterozoic Crustal Evolution by : K.C. Condie
Download or read book Proterozoic Crustal Evolution written by K.C. Condie and published by Elsevier. This book was released on 1993-02-03 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a final product of the International Geological Correlation Program (IGCP) Project 217, this volume brings together significant advances in the understanding of Proterozoic crustal evolution. This IGCP Project focussed on nine research objectives: 1) Comparison of Archean and Proterozoic supracrustal assemblages to more fully understand differences between Archean and post-Archean tectonic regimes; 2) To more fully understand the geochemical differences between Archean and post-Archean sediments and to evaluate the various factors that control sediment composition; 3) From combined U/Pb zircon and whole-rock Sm/Nd studies, to see if the apparent 2.4-2.0 continental crust "generation gap" is real; 4) To employ new techniques in the dating of individual zircons to more fully understand Proterozoic tectonic history and the role of crustal reworking; 5) From trace element ratios and Nd isotopic data from basalts, to better understand Proterozoic mantle evolution; 6) To encourage more detailed studies of the anorogenic granite-anorthosite association to better understand its origin and significance in terms of crustal evolution; 7) From combined Nd, Pb, and Sr isotopic data, to more precisely estimate the amount of new continental crust formed during the Proterozoic; 8) To encourage joint P-T and geochronological studies of Proterozoic and high-grade terranes to better understand Proterozoic orogenesis: and 9) To try and understand why hydrothermal precious metal deposits are relatively rare in the Proterozoic compared to both the Archean and the Phanerozoic. The book should be of interest to professionals in the geosciences (especially geochemists, petrologists and structural geologists) and graduate students in the same fields.
Book Synopsis Earth Accretionary Systems in Space and Time by : Peter Anthony Cawood
Download or read book Earth Accretionary Systems in Space and Time written by Peter Anthony Cawood and published by Geological Society of London. This book was released on 2009 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accretionary orogens form at convergent plate boundaries and include the supra-subduction zone forearc, magmatic arc and backarc components. They can be broken into retreating and advancing types, based on their kinematic framework and resulting geological character.Accretionary systems have been active throughout Earth history, extending back until at least 3.2 Ga, and provide an important constraint on the initiation of horizontal motion of lithospheric plates on Earth. Accretionary orogens have been responsible for major growth of the continental lithosphere, through the addition of juvenile magmatic products, but are also major sites of consumption and reworking of continental crust through time.The aim of this volume is to provide a better understanding of accretionary processes and their role in the formation and evolution of the continental crust. Fourteen papers deal with general aspects of accretion and metamorphism and discuss examples of accretionary orogens and crustal growth through Earth history, from the Archaean to the Cenozoic.

Book Synopsis Supercontinents, Orogenesis and Magmatism by : R.D. Nance
Download or read book Supercontinents, Orogenesis and Magmatism written by R.D. Nance and published by Geological Society of London. This book was released on 2024-04-24 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a tribute to the career of J. Brendan Murphy and features papers by over 100 authors from countries all over the world: a testament to the high-profile and far-reaching influence of Brendan’s work. The topics covered fall into three broad categories that encompass Brendan’s main fields of influence: (1) supercontinents and the supercontinent cycle, including reconstructions and modelling; (2) orogenesis and terranes, with a focus on the Appalachian–Variscan and Central Asian orogenic belts and the oceans with which they are associated; and (2) magmatism and magmatic processes, centring on the geochemistry and isotopic compositions of magmas in arc and rift setting. Like Brendan’s own research, the scope of the papers spans the globe and ranges from strongly field-based studies to conceptual analyses. All of the articles, however, are focused on unravelling some critical aspect of geology or aimed at clarifying some crucial geological process. Hence, they also share a theme common to Brendan’s many contributions in emphasizing the importance of process-oriented research.
