Available in PDF, EPUB and Kindle. Book excerpt: In Earth evolution, mountain belts are the loci of crustal growth, reworking and recycling. These crustal-scale processes are unravelled through microscale investigations of textures and mineral assemblages of metamorphic rocks. Multiple episodes of metamorphism, re-equilibration and deformation, however, generally produce a complex and tightly interwoven pattern of microstructures and assemblages. Over the last two decades, the combination of advanced computing and technological capabilities with new concepts has provided a vast array of novel petrological tools and high-resolution/high-sensitivity techniques for microanalysis and imaging. Such novel approaches are proving fundamental to untangling the enigma represented by metamorphism with an unprecedented level of detail and confidence. As a result, the first decade and a half of this century has already seen the tumultuous development of new research avenues in metamorphic petrology. This book aims to provide a timely overview of the state of the art of this field, of newly developed petrological techniques, future advancements and significant new case studies.
Download or read book Precambrian Ophiolites and Related Rocks written by T.M. Kusky and published by Elsevier. This book was released on 2004-10-26 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments have shown that many full and partial ophiolites are preserved in Precambrian cratons. This book provides a comprehensive description and discussion of the field aspects, geochemistry, geochronology and structure of the best of these ophiolites. It also presents syntheses of the characteristics of ophiolites of different ages, and an analysis of what the characteristics of these ophiolites mean for the thermal and chemical evolution of the earth. This title emphasizes new studies of Precambrian Geology that have documented ophiolites, ophiolitic fragments, and ophiolitic melanges in many Precambrian terranes. Each chapter focuses on individual Precambrian ophiolites or regions with numerous Precambrian ophiolites, and covers field aspects, petrology, geochemistry, geochronology, and other descriptive aspects of these ophiolites, it also delves into more theoretical and speculative aspects about the interpretation of the significance of these ancient ophiolites.

Download or read book Earth s Oldest Rocks written by Martin J. Van Kranendonk and published by Elsevier. This book was released on 2018-09-26 with total page 1114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth's Oldest Rocks, Second Edition, is the only single reference source for geological research of early Earth. This new edition is an up-to-date collection of scientific articles on all aspects of the early history of the Earth, from planetary accretion at 4.567 billion years ago (Ga), to the onset of modern-style plate tectonics at 3.2 Ga. Since the first edition was published, significant new advances have been made in our understanding of events and processes on early Earth that correspond with new advances in technology. The book includes contributions from over 100 authors, all of whom are experts in their respective fields. The research in this reference concentrates on what is directly gleaned from the existing rock record to understand how our planet formed and evolved during the planetary accretion phase, formation of the first crust, the changing dynamics of the mantle and style of tectonics, life's foothold and early development, and mineral deposits. It is an ideal resource for academics, students and the general public alike. - Advances in early Earth research since 2007 based primarily on evidence gleaned directly from the rock record - More than 50% of the chapters in this edition are new and the rest of the chapters are revised from the first edition, with more than 700 pages of new material - Comprehensive reviews of areas of ancient lithosphere from all over the world, and of crust-forming processes - New chapters on early solar system materials, composition of the ancient atmosphere-hydrosphere, and overviews of the oldest evidence of life on Earth, and modeling of early Earth tectonics
Download or read book A Scientific Bibliography of the Far Northern Drakensberg written by Rodney Moffett and published by UJ Press. This book was released on 2023-04-14 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Scientific Bibliography of the “Far Northern Drakensberg” is a continuation by the Afromontane Research Unit of the University of the Free State (ARU) to document published and other similar works on the mountains of the summer rainfall area of South Africa. It follows “A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands” which was published in 2020 (Moffett 2020), and which covered the area between the North-Eastern Cape and the North-Eastern Free State. The current work extends this northward by including articles and publications dating back to 1875 (E.Cohen, on the Lydenburg goldfields) reaching as far as the Wolkberg and Woodbush near Tzaneen in Limpopo Province. Figure 1 shows the boundary of the area covered, and although referred to as the Far Northern Drakensberg in this work, it is identical to that described as the LMEE, Limpopo, Mpumalanga & Eswatini Escarpment by Clarke et al (2022). Although slightly separate from the “lower” escarpment, the mountainous Barberton and adjacent Eswatini area, as well as the Leolo Mountains in eastern Sekhukhuneland are also included. Details on how the boundary in figure 1 was determined are given in Clark et al (2022). Bibliographies on two further ranges in the summer rainfall area, viz. the Magaliesberg in Gauteng province and the Soutpansberg in Limpopo province are to be the subject of future compilations.
Download or read book Earliest Life on Earth Habitats Environments and Methods of Detection written by Suzanne D. Golding and published by Springer Science & Business Media. This book was released on 2010-09-02 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume integrates the latest findings on earliest life forms, identified and characterised in some of the oldest rocks on Earth. New material from prominent researchers in the field is presented and evaluated in the context of previous work. Emphasis is placed on the integration of analytical methods with observational techniques and experimental simulations. The opening section focuses on submarine hot springs that the majority of researchers postulates served as the cradle of life on Earth. In subsequent sections, evidence for life in strongly metamorphosed rocks such as those in Greenland is evaluated and early ecosystems identified in the well preserved Barberton and Pilbara successions in Southern Africa and Western Australia. The final section includes a number of contributions from authors with alternate perspectives on the evidence and record of early life on Earth. Audience This volume will be valuable to researchers and graduate students in biogeosciences, geochemistry, paleontology and geology interested in the origin of life on earth.

This book was released on 2024-01-11 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation of key mineral phases such as zircon, apatite, titanite, rutile, monazite, xenotime, allanite, baddeleyite and garnet, explored in this book, has provided breakthroughs in our understanding of continental crust composition and evolution, as well as the timing, conditions, petrogenetic and geodynamic processes related to its growth and reworking. Therefore, the continuing development of analytical techniques, improvement of tools, data handling, processing, and interpretation allow us to extract and better understand these complex geological processes. This special publication aims at showcasing contributions reviewing the tools and applications of these key minerals, recent technique developments, and new applications using focused case studies investigating igneous, metamorphic and/or detrital rocks that help us put together the continental crust evolution puzzle. This volume highlights the progress made in studies using these key minerals and their future potential.
