This book was released on 2021-08-20 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas of Deformed and Metamorphosed Rocks from Proterozoic Orogens is a richly illustrated reference book featuring over 660 full-color field images of a range of lithologies from some Proterozoic terrains that were subjected to multiple events of magmatism, deformation, metamorphism, and metasomatism. The Atlas focuses on amphibolite to granulite facies lithologies and associated ma?c-ultrama?c rocks from Proterozoic orogens of India, Sri Lanka, Botswana, South Africa, East Antarctica, and Western Australia. Each chapter in the book begins with a brief review of geology, including deformation and metamorphic history, along with a regional geological map to help readers to visualize the ?eld observations in the relevant geological context. Each image is accompanied by a concise description providing location, lithology, structural fabric, possible deformational history, metamorphic features, partial melting, metasomatism, and other important crustal processes. This Atlas is an important source of information for a broad range of earth scientists, graduate and undergraduate students, researchers, academicians, and other professionals. This book will form a great treasure to those geoscientists who never had an opportunity to visit any of the Proterozoic orogenic belts. Features over 660 full-color photographs representing typical lithologies and associated structural, metamorphic features, and other crustal processes from different Proterozoic orogens Highlights the significance of field photographs in advancing new knowledge which may provide pathways for new research Covers many important Proterozoic terranes of East Gondwana Presents regional geologic maps from each Proterozoic orogen

This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 1976 Lucian B. Platt organized a highly successful Penrose Confer ence on The Formation of Rock Cleavage at Bryn Mawr College in Penn sylvania, U. S. A. The meeting drew together about 70 specialists from both sides of the Atlantic and from Australasia, who contributed discussions on various aspects of rock cleavage and its formation. Even early in the meet ing it became clear to the participants that they lacked a common terminol ogy, that often the same technical word implied different things to different people and that observables and descriptors were loosely defined. In an at tempt to improve communication the present editors contacted about 190 workers after the conference with a view to compiling a set of photographs with captions to illustrate exactly what workers were talking about. As a re sult the compilation was published as a limited edition by an inexpensive offset process at the University of Tasmania. The success of that provisional edition of the Atlas of Rock Cleavage and the responses of the readers prompted us to make a more extensive collection of material, contact a wider range of workers and, with the support of Dr. Konrad Springer, to publish the present higher-quality reproduction of the contributors' plates.

Download or read book Proterozoic Orogens of India written by T.R.K. Chetty and published by Elsevier. This book was released on 2017-07-12 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proterozoic Orogens of India: A Critical Window to Gondwana provides a unique opportunity to understand a cross-section of the well-exposed and best-studied part of Earth’s crust and the processes of continental collision. It covers pulses of reworking processes and their impact on magmatism, metamorphism and deformational history of Proterozoic orogens vis-à-vis the supercontinental formation. The details of structural architecture, crustal blocks, shear zone systems, magmatism, metamorphism, geochemical and isotopic signatures, mineralization and tectonic models of all the Proterozoic orogens of India are discussed along with excellent illustrations reflecting the field-based, multi-scale structural and geological data sets. The spatial distribution, geometry, kinematics and transpressional strain of the shear zone systems (mostly suture zones), which are critical to all conceptual models dealing with tectono-metamorphic history of Proterozoic orogens of India, are also covered. The book summarizes and integrates the state-of -the art understanding of the structural architecture, lithological assemblages, petrological, geochemical, geochronological and geophysical aspects of the Proterozoic orogens of India. Includes a much needed state-of-the-art tectonic summary of the voluminous data that has emerged from the Protrozoic orogens of India in the last 2-3 decades Authored by a well-established expert with more than 30 years of experience in the field based, multi-scale structural geological studies of the ancient orogens of India Covers up-to-date reviews and models of Proterozoic orogens developed in the Indian shield over the past 2.5 billion years of Earth history
Download or read book Nature and Style of Deformation in the Foreland of the Early Proterozoic Penokean Orogen Northern Michigan written by J. S. Klasner and published by . This book was released on 1991 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evidence for Early Proterozoic north-verging folding and thrusting in the continental foreland of the Penokean orogen is present in two widely separated areas in northern Michigan. In the eastern part of the exposed orogen, asymmetric to over-turned folds in the Early Proterozoic Michigamme Formation suggest an initial (D1) phase of possibly north verging thin-skinned deformation. A second phase (D2 ) is characterized by a more thick skinned deformation consisting of northward thrusting of Archean gneiss and overlying Early Proterozoic quartzite along ductile thrust faults. Crosscutting shear zones indicate a third phase (D3 ) of deformation involving east- northeast thrusting of Archean gneiss. Thick-skinned deformation D2 and D3 phases include spaced fracture cleavage, kink folds, and lineations in D1, foliation surfaces. Near the west end of the exposed orogen in Michigan, bedding-cleavage relationships in the Early Proterozoic Tyler Formation also indicate northward tectonic transport. These structures, which are interpreted as D1 lie along the north edge of the Archean Puritan batholith and associated Archean greenstone. The north-verging structures in the northern Michigan segment of the Penokean orogen were formed approximately 1,850 Ma during collision of the Wisconsin magmatic terranes with the continental foreland of Michigan, Wisconsin, and Minnesota.

Download or read book The Minor Structures of Deformed Rocks written by Lionel E. Weiss and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perhaps the most striking impression gained by a geologist during twenty years of field work with deformed rocks in many parts of the world is that the minor structures in these rocks are surprisingly uniform in their properties and restricted in their variety. In fact, a relatively short and simple list can include all structures which are both of common occurrence and of use to the structural geologist in his attempts to understand the structure and evolution of a deformed geologic body. The photographs in this book have been selected to illustrate as clearly as possible the obvious characteristics of the common minor structures of deformed rocks. I have tried to make this selection truly representative in spite of two factors that have affected the choice. First, I have included only photographs made during my own field work. No doubt the selection could have been greatly improved in both quality and variety by including photographs made by other geologists. Second, the photographs necessarily reflect my own inte rests and not those of every geologist concerned with deformed rocks. Consequently, for example, great emphasis has been placed on folds, whereas faults and joints are entirely omitted.
