Earth Accretionary Systems in Space and Time 

Earth Accretionary Systems in Space and Time pdf

Book Description:

Accretionary orogens form at convergent plate boundaries, including 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’s history, extending until at least 3.2 Ga, and provide a significant constraint on the initiation of horizontal motion of lithospheric plates on Earth. Accretionary orogens have been responsible for the major growth of the continental lithosphere through the addition of juvenile magmatic products. Still, they are also significant 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 accretion and metamorphism and discuss examples of accretionary orogens and crustal growth throughout Earth’s history, from the Archaean to the Cenozoic. The Geological Society of London was founded in 1807; the Geological Society of London is the oldest geological society in the world and one of the largest publishers in the Earth sciences. The Society publishes a wide range of high-quality peer-reviewed titles for academics and professionals working in the geosciences and enjoys an enviable international reputation for the quality of its work. The many areas in which we publish in include:-Petroleum geology-Tectonics, structural geology and geodynamics-Stratigraphy, sedimentology and paleontology-Volcanology, magmatic studies and geochemistry-Remote sensing-History of geology-Regional geology guides
