Book excerpt: Granitoids form the bulk of the Archean continental crust and preserve key information on early Earth evolution. India hosts five main Archean cratonic blocks (Aravalli, Bundelkhand, Singhbhum, Bastar and Dharwar). This book summarizes the available information on Archean granitoids of Indian cratons. The chapters cover a broad spectrum of themes related to granitoid typology, emplacement mechanism, petrogenesis, phase-equilibria modelling, temporal distribution, tectonic setting, and their roles in fluid evolution, metal delivery and mineralizations. The book presents a broader picture incorporating regional- to craton-scale comparisons, implications for Archean geodynamic processes, and temporal changes thereof. This synthesis work, integrating modern concepts on granite petrology and crustal evolution, offers an irreplaceable body of reference information for any geologist interested in Archaean Indian granitoids.

Book Synopsis Geological and Geo-Environmental Processes on Earth by : Arun Kumar Shandilya

Download or read book Geological and Geo-Environmental Processes on Earth written by Arun Kumar Shandilya. This book was released on 2021-11-01. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume dedicated to late Prof. P.S. Saklani addresses the multidisciplinary themes pertaining to role of tectonism and magmatism in Crustal Evolution and global distribution of metallic and non metallic mineral deposits. It gives valuable information on geodynamic evolution, structural, petrological, isotopic, metamorphic, geochemical and geochronological attributes of continental and oceanic crust and is challenging reassessments of the existing paradigms. It addresses the implication of magmatism, metallogeny and application of geochronological ages (U-Pb SHRIMP age, Lu-Hf isotopic system; detrital zircons). This book also advocates the role of tectonics in contamination of ground water, and control on drainage pattern and geothermal systems. It explores the vulnerability of earth towards natural hazards viz. earthquakes, floods, cyclones, tsunami, volcanism, cyclones and drought. This volume throws light on the applications of remote sensing, GIS (Geographical Information System) and SRTM data for evaluation of the morphometric and morphotectonic parameters and exploring the susceptibility of river basins toward erosion and flood. It will be beneficial to graduate and post-graduate students as well as professionals and researchers.

Book Synopsis Geodynamics of the Indian Plate by : Neal Gupta

Download or read book Geodynamics of the Indian Plate written by Neal Gupta. This book was released on 2020-02-28. Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights on new geological, tectonic, and climatic developments in India through a time progression from the Archean to the Anthropocene that are captured via authoritative entries from experts in earth sciences. This volume aims to bring graduate students and researchers up to date on the geodynamic evolution of the Indian Plate; concepts that have so far resulted in a rather uneven treatment of the subject at different institutions. The book is divided into 4 sections and includes perspectives such as the formation and evolution of the Indian crust in comparison to its neighbors such as Antarctica, Africa and Australia; the evolution of Precambrian cratons and sedimentary basins of India; and a summary account of early life reported in the Indian stratigraphic record. Readers will also discover the key recent research into the neotectonics, tectonic geomorphology, and paleoseismology of the Himalayan Front. Researchers and students in geology, earth sciences, sedimentology, paleobiology and geography will find this book appealing.

Download or read book Post-Archean Granitic Rocks written by V. Janoušek. This book was released on 2020-07-02. Available in PDF, EPUB and Kindle. Book excerpt: Granites (sensu lato) represent the dominant rock-type forming the upper–middle continental crust but their origin remains a matter of long-standing controversy. The granites may result from fractionation of mantle-derived basaltic magmas, or partial melting of different crustal protoliths at contrasting P–T conditions, either water-fluxed or fluid-absent. Consequently, many different mechanisms have been proposed to explain the compositional variability of granites ranging from whole igneous suites down to mineral scale. This book presents an overview of the state of the art, and envisages future avenues towards a better understanding of granite petrogenesis. Particular emphasis of this Volume is on the following topics: Compositional variability of granitic rocks generated in contrasting geodynamic settings during Proterozoic to Phanerozoic Periods, Main permissible mechanisms producing subduction-related granites, Crustal anatexis of different protoliths, and the role of water in granite petrogenesis, New theoretical and analytical tools available for modelling whole-rock geochemistry, in order to decipher the sources and evolution of granitic suites.
