This book was released on 2012-04-13 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a length of about 1200 km, the Son-Narmada-Tapti Lineament (NSL) is one of the most prominent geomorphic features in the Indian subcontinent. Anomalous conductive bodies are delineated at mid-lower crustal depths below major earthquake epicentral zones. The region has been interpreted as the collision zone of the Indian Plate with the Eurasian Plate. The NSL zone is therefore also known to be the second most important tectonic feature in the Indian geology, after the Himalayas. The present thesis describes significant new insight into the seismotectonics of this Central India tectonic zone, based on thorough magnetotelluric studies. The main objectives of the present study are: (i) to delineate subtrappean sediments across the NSL region along four different traverses, (ii) to understand the characterization of geo-electrical structure of the crust and examine the nature of geo-electrical signatures of the known faults, (iii) to integrate the results with other geophysical data such as seismicity, gravity and heat flow, in order to understand the tectonic scenario of the region. Deep electromagnetic (magnetotelluric) analyses were integrated in this study with gravity, seismic and heat flow studies and distinct, delineated deep crustal features. The resulting high conductivity is justified with the presence of fluids at mid-lower crustal depths. The migration of these fluids from mantle to mid-lower crustal depths through pre-existing brittle fracture/fault zones were obviously caused by the plume related to the Deccan volcanism. Migration of the fluids generated a higher fluid pressure along the faults and resulted in earthquakes. Based on the geo-electric sections derived along the four traverses of the Narmada-Son Lineament Zone, the present study gives important clues on the subduction/collision history in this important tectonic zone.

The book presents both background and applications in one cohesive volume for researchers and students of geophysics and geology. Presents all the information and metadata of the Indian continental crust and its neighbouring regions in a cohesive way Provides basic knowledge of the Indian subcontinent to support the discussion of seismic studies related to crustal structure Includes all new chapter covering global applications and synthesis of the findings and observations
Book Synopsis The Lithosphere Beneath the Indian Shield by : Ashoka G. Dessai
Download or read book The Lithosphere Beneath the Indian Shield written by Ashoka G. Dessai and published by Springer Nature. This book was released on 2020-09-24 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2008-08-22 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the outcome of about 30 years of research in the field of earthquake seismology in various parts of South Asia. It comprehensively deals with topics raning from plate tectonics to seismic waves in general. State-of-the-art techniques in earthquake location/relocation, fault plane solution, waveform inversion, seismic tomography, fractals etc. are discussed, and the results are interpreted in terms of seismic source processes in the region.
Book Synopsis Earthquakes of the Indian Subcontinent by : C. P. Rajendran
Download or read book Earthquakes of the Indian Subcontinent written by C. P. Rajendran and published by Springer Nature. This book was released on 2022-02-28 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights some of the interesting recent and historical earthquakes (1803 Uttarkashi, 1819 Kutch, 1897 Shillong, 1905 Kangra, 1934 Nepal-Bihar, 1950 Upper Assam, 1967 Koyna, 1993 Killari, 1997 Jabalpur, 2001 Bhuj, 2004 Sumatra-Andaman, 2005 Kashmir, and 2015 Nepal) that occurred in India and in the vicinity. The tectonic and geodynamic significance of the modern (after the advent of global network) earthquakes in relation to some of the historical earthquakes like the 1819 Kachchh and 1897 Shillong and 1934 Nepal-Bihar earthquakes in the light of newer understanding is discussed. It also contains detailed expositions of seismotectonics and mechanisms of each earthquake. It concludes with touching upon future earthquake hazard scenario in India in view of the present and past earthquakes.

Book Synopsis Precambrian Basins of India by : R. Mazumder
Download or read book Precambrian Basins of India written by R. Mazumder and published by Geological Society of London. This book was released on 2015-04-02 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Memoir provides a comprehensive review of the Precambrian basins of the four Archaean nuclei of India (Dharwar, Bastar, Singhbhum and Aravalli-Bundelkhand), encompassing descriptions of the time-space distribution of sedimentary-volcanic successions, the interrelationship between tectonics and sedimentation, and basin histories. Studies of 22 basins within the framework of an international basin classification scheme deepen an understanding of the basin architecture especially for cratonic basins. Most Indian sedimentary successions formed as cratonic to extensional-margin rift and thermal-sag basins, some reflecting mantle plume movement, subcrustal heating or far-field stress. This Memoir shows that Phanerozoic plate-tectonic and sequence stratigraphic principles can be applied to the Precambrian basins of large Archaean provinces. The differences between the stratigraphic architecture of the Indian Precambrian and examples of Phanerozoic basin-fill successions elsewhere are ascribed to variable rates and intensities of the controls on accommodation and sediment supply, and changes inherent in the evolution of the hydrosphere-atmosphere and biosphere systems.
