The Lithosphere Beneath the Indian Shield by Ashoka G. Dessai Pdf

This book explores the geotectonic evolution of the lithosphere beneath the Indian Shield, which comprises a collage of cratons variously bounded by mobile belts and palaeo-rifts. The lithosphere beneath these is fairly thin compared to other cratons worldwide, petrologically varied and shows considerable variation in thickness with depth both intra-craton and among cratons. Moreover, it has been subjected to the influence of repeated magmatic episodes from Proterozoic to Palaeocene, which have variously impacted different parts of the shield. The thermotectonic influence on constituent cratons is variable depending on the evolutionary history. This book discusses the impact of successive tectonomagmatic events on the evolution of the deep crust and shallow mantle, and their Phanerozoic modification as gleaned through the xenolith window. The book provides a petrotectonic perspective on the deep crust and shallow mantle from direct samples brought up as xenoliths of deep lithologies, and offers a comprehensive overview for students, researchers, academics and professionals, integrating the results of petrological studies of deep lithologies and geophysical investigations to (i) shed light on the physico-chemical and thermal structure of the lithosphere from an array of geotectonic settings and (ii) gain insights into the spatio-temporal evolution of the Indian Shield. An in-depth guide critical thinking on the complex issue of mantle differentiation, magmatism, lithosphere modification and crustal growth over time, the book allows readers to gain a better understanding of the processes that affect the lithosphere and shape the crust on which we live.

Geodynamics of the Indian Plate by Neal Gupta,Sampat K. Tandon Pdf

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.

Zagros, Hindu Kush, Himalaya by F. M. Delany,H. K. Gupta Pdf

Published by the American Geophysical Union as part of the Geodynamics Series, Volume 3. The International Geodynamics Project focussed attention on processes within the earth responsible for the movement of the lithospheric blocks. At anyone time, strong tectonic activity appears limited to a few mobile belts. Most of the present-day seismic activity is confined to the Circum-Pacific belt, the Alpide belt and the mid-oceanic ridges. These belts include oceanic and continental rift systems, the island arcs and young folded mountains. Continent to continent collision of the Eurasian and the Indian plates is generally believed to be responsible for the origin of the Himalaya, the tectonics of this region and the neighbouring south and central Asia. To focus attention on geodynamic problems in this relatively much less known Alpine-Himalayan region bounded by Iran in the West and Burma in the East, the Inter-Union Commission on Geodynamics formed a separate Working Group 3b under the Chairmanship of Hari Narain. Later, in 1975, this Working Group 3b on "Geodynamics of the Alpine-Himalayan region, East" was given independant status and re-numbered as Working Group 6.

Dyke Swarms: Keys for Geodynamic Interpretation by Rajesh Srivastava Pdf

Dykes occur in a wide variety of geological and tectonic settings and their detailed study through space and time is imperative for understanding several geological events. Dykes are believed to be an integral part of continental rifting and when they occur as spatially extensive swarms of adequate size, they can be of immense utility in continental reconstructions and also help to identify Large Igneous Provinces (LIPs). It is known that continental flood basalts and major dyke swarms have their origin related in some way to the up-rise of hot mantle plumes which may lead to rifting and eventual continental break-up. Dykes signify crustal extension and are important indicators of crustal stabilisation events, supercontinental assembly and dispersal, crust-mantle interaction and play a significant role in the delineation of crustal provinces as well as in deciphering crustal evolution events. Many economic mineral deposits of the world are also associated with a variety of dykes. The volume will provide state-of-the-art information on all aspects of dykes with emphasis on the origin, evolution and emplacement of dykes.

Tectonics of the Eastern Continental Margin of India by Dr. K. S. R. Murthy,A. S. Subrahmanyam,Vandrapu Subrahmanyam Pdf

Passive continental margins are formed within a single lithospheric plate in which the continental crust adjoins the oceanic crust. Assessment of the geological potential of these margins requires a comprehensive knowledge on the history of the ocean—from the time of pre-rifting events to the present. Tectonics of the Eastern Continental Margin of India presents the different aspects of a passive margin such as its evolution, tectonics, and associated hazards, taking the Eastern Continental Margin of India (ECMI) as a case study. It discusses the passive margin and focuses on its origin, morphology, structure, and exploration potential; describes the major structural lineaments delineated from the geophysical data over the ECMI; and attempts to explain the geodynamic evolution of this passive margin. A preliminary estimate on the seismic hazards associated with ECMI is also presented in the book.

Structural Geometry of Mobile Belts of the Indian Subcontinent by Tapas Kumar Biswal,Sumit Kumar Ray,Bernhard Grasemann Pdf

This book summarizes the latest research on the structural geology of the mobile belts of the Indian subcontinent including the Himalayas, NE Himalayas, Bangladesh thrust belt, Andaman subduction zone, the Aravalli‐Delhi, the Central India Tectonic Zone, the Singhbhum, the Eastern Ghats and the Southern granulite terrane. It offers essential information on deformational structures in the mobile belt, such as folding patterns, the character of the shear zone, shear strain analysis, and faults, as well as fault zone rocks. The findings presented here are based on field observations, mapping, sampling and analysis work (e.g. petrographic studies), as well as limited geochemical and geochronological analysis to support the findings. A discussion on the structural evolution of these mobile belts and their connections with other belts rounds out the coverage.

Geological and Geo-Environmental Processes on Earth by Arun Kumar Shandilya,Vinod Kumar Singh,Suresh Chandra Bhatt,Chandra Shekhar Dubey Pdf

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.

Tectonics of the Indian Subcontinent by A.K. Jain,D.M. Banerjee,Vivek S. Kale Pdf

This books documents the salient characters of the tectonic evolution of the Indian subcontinent. It showcases the well investigated subcontinent of Gondwana. The book is linked to an updated geological and tectonic map of this region on 1:12,000,000 in scale. The Indian subcontinent displays almost uninterrupted and unique the geological history since about Eo-Archean (~3800 Ma) to recent, with the development of many Proterozoic deformed and metamorphosed fold belts around Archean nuclei, and enormously thick undeformed platform deposits. After their stabilization during late Proterozoic, the subcontinent underwent Paleozoic rifting and deposition of coal-bearing thick sequences, followed by enormously-thick outpouring of Deccan volcanics as a consequence of huge mantle plume. The youngest event in its evolution is the Cenozoic Himalayan Orogenic Mountains, spanning the area between Nanga Parbat and Namcha Barwah; a part of which extends both in Pakistan and Myanmar.

Bouguer Gravity Regional and Residual Separation by K. Mallick,A. Vasanthi,K.K. Sharma Pdf

The process of regional-residual separation in potential field is age-old. Broadly, there are two techniques for regional-residual resolution, viz., graphical and analytical. Both the techniques have their own respective shortcomings. In this book, the authors have described the technique based on finite element method in which only eight (or twelve) nodal observed gravity values are used for the regional computation, thereby eliminating the possible contamination of anomalous fields and also the technique does not assume an explicit model and physical properties like density of rocks etc. in the regional computation. The book discusses the advantages of this technique viz., it is not site-specific; the computation is independent of any prior assumptions as to the form and depth of shallow or deeper structures; it can handle data distributed at random or on a regular grid on the map space; and the neighbouring surveys join smoothly. The book focuses on application of this new technique which has been demonstrated in different fields, such as hydrocarbon, minerals and groundwater, structural studies, earthquake and engineering studies and impact structures.
