Book Synopsis Himalayan Neotectonics and Channel Evolution by : Harendra Nath Bhattacharya

Download or read book Himalayan Neotectonics and Channel Evolution written by Harendra Nath Bhattacharya. This book was released on 2022-07-07. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on neotectonic movements and river channel evolution of the Indian subcontinent, with special reference to the Himalayan Neotectonics. Neotectonic movements have played an important role in channel evolution in tectonically active zones especially for the mountain chains, foredeeps and active deltas. The book addresses the issues of the channel evolution in neotectonically active domains of India. It aims at readers of India as well as abroad, interested in earth sciences, geomorphology, tectonics, physical geography and river forms and processes of India.

Book Synopsis Floods in the Ganga–Brahmaputra–Meghna Delta by : Aznarul Islam

Download or read book Floods in the Ganga–Brahmaputra–Meghna Delta written by Aznarul Islam. This book was released on 2023-02-14. Available in PDF, EPUB and Kindle. Book excerpt: This volume covers the floods of the major rivers of the Ganga-Brahmaputra-Meghna (GBM) Delta, and storm surge related coastal floods in these regions. The book is dedicated to addressing floods from an integrated physical-social perspective to provide students and researchers with a holistic understanding of floods in terms of both human and geomorphological aspects. The systematic coverage of all the major rivers and coastal areas in the GBM delta and surrounding regions will foster a clear comprehension of this dense reservoir of population, where thousands of people are impacted every year due to flood hazards and agricultural destabilization. This comprehensive treatment of flood issues in the region covers flash floods, fluvial floods, fluvio-tidal floods, and coastal floods, and outlines flood management strategies to maintain ecological integrity and environmental stability, and prevent harmful impacts of future floods. The book is intended for students and researchers in earth and environmental sciences, especially geomorphology, hydrology, geography, geology, natural resources management, and regional planning.

Book Synopsis Neotectonism in the Indian Subcontinent by : K.S. Valdiya

Download or read book Neotectonism in the Indian Subcontinent written by K.S. Valdiya. This book was released on 2017-11-16. Available in PDF, EPUB and Kindle. Book excerpt: An erudite work on tectonic resurgence in Late Quaternary time of the Indian subcontinent embracing India, Pakistan, Nepal, Bhutan, and Bangladesh, Neotectonism in the Indian Subcontinent dwells on the causes and consequences of tectonic events that fashioned the landscape of a land characterized by a fragmented framework. The narratives on the structural and geomorphic developments during the morphogenic phase of the geodynamic history of the Indian subcontinent explain many phenomena. These include the tremendous height and spectacular structural-geomorphic architecture of the Himalaya, and the behaviour of wayward rivers in the sinking and rising Indo-Gangetic Plains. In addition are the shifting, deflection, piracy, and even disappearance of rivers and streams in the dry desertic terrane of western India, as well as the unique drainage pattern of the ruptured and rifted plateaus and coastal belts of Peninsular India. The formation of huge lakes due to river ponding in the stable continental shield in Karnataka is also explained. All of these phenomena are accompanied by profuse illustrations. Neotectonism in the Indian Subcontinent portrays the evolution of the extraordinary landforms and landscapes of the subcontinent, constituted by multiple terranes of contrasted lithostructural architecture and distinctive geomorphic layout—each with an altogether different geological history. It chronicles events of crustal unrest or tectonic turmoil manifested as displacement, subsidence, and uplift of the ground with bizarre drainage changes and episodic seismicity. This book caters to planners, engineers, and hazard managers, but also satisfies the curiosity of those who are interested in understanding the formation of the Indian subcontinent. Identifies areas and belts recurrently ravaged by geological hazards resulting from neotectonic activities Provides a wealth of information on neotectonic movements and consequent modification of landscape, drainage aberrations, and ground vulnerability, including references that also provide additional resources for those who seek to pursue comprehensive investigations Includes much new observation and refreshing interpretation to explain many of the striking landforms of the region

Book Synopsis Tectonics of the Himalaya by : S. Mukherjee

Download or read book Tectonics of the Himalaya written by S. Mukherjee. This book was released on 2015-09-28. Available in PDF, EPUB and Kindle. Book excerpt: The Himalayan mountain belt, which developed during the India–Asia collision starting about 55 Ma ago, is a dramatically active orogen and it is regarded as the classic collisional orogen. It is characterized by an impressively continuous 2500 km of tectonic units, thrusts and normal faults, as well as large volumes of high-grade metamorphic rocks and granites exposed at the surface. This constitutes an invaluable field laboratory, where amazing crustal sections can be observed directly in very deep gorges. It is possible to unravel the tectonic and metamorphic evolution of litho-units, to observe the mechanisms of exhumation of deep-seated rocks and the propagation of the deformation. Himalayan tectonics has been the target of many studies from numerous international researchers over the years. In the last 15 years there has been an explosion of data and theories from both geological and geophysical perspectives. This book presents the results of integrated multidisciplinary studies, including geology, petrology, magmatism, geochemistry, geochronology and geophysics, of the structures and processes affecting the continental lithosphere. These processes and their spatial and temporal evolution have major consequences on the geometry and kinematics of the India–Eurasia collision zone.

Book Synopsis Crustal Architecture and Evolution of the Himalaya-Karakoram-Tibet Orogen by : R. Sharma

Download or read book Crustal Architecture and Evolution of the Himalaya-Karakoram-Tibet Orogen written by R. Sharma. This book was released on 2019-09-27. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises 17 contributions that address the architecture and geodynamic evolution of the Himalaya–Karakoram–Tibet (HKT) system, covering wide aspects, from the active seismicity of the present day to the remnants of the Proterozoic orogen. The articles investigate the HKT system at different scales, blending field research with laboratory studies. The role of various lithospheric components and their inheritance in the geodynamic and magmatic evolution of the HKT system through time, and their links to global geological events, are studied in the field. The laboratory research focuses on the (sub-)micrometre scale, detailing micro-structural geology, crystal chemistry, geochronology, and the study of circulating fluids, their preservation (trapped in fluid inclusions) and their evolution, distribution, migration and interaction with the solid host. An orogen over 2000 km long can be understood only if the processes at the nanometre and micrometre scales are taken into account. The contributions in this volume successfully combine these scales to enhance our understanding of the HKT system.
