Active Tectonics of Kumaun and Garhwal Himalaya


Book Description

The book contributes to understanding the pattern of strain release and the level of seismic hazard imposed by large-great earthquakes in the frontal fold-thrust belts of Kumaun and Garhwal regions of Uttarakhand. The motivation for active fault studies and their characterization have been emphasized. The book presents the compilation of knowledge garnered in multidisciplinary or proxy studies involved in the understanding of seismic hazard in general and Kumaun–Garhwal Himalaya regions in particular with lucid new maps draped on modern Cartosat or SRTM DEM data. It also discusses satellite image calibration, active faults identifications, and map productions with flowchart. The book discusses window-wise active fault elements with attributes together with the tectonic geomorphic map. It also includes active fault scarp with topographic profile along with field photographs. Finally, it reviews all existing seismotectonic models of the Himalaya, its earthquake hazard, and its vulnerability, specifically for Kumaun and Garhwal regions.




Geodynamics of the Indian Plate


Book Description

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.

Ethnobotany of the Himalayas


Book Description

Research in recent years has increasingly shifted away from purely academic research, and into applied aspects of the discipline, including climate change research, conservation, and sustainable development. It has by now widely been recognized that “traditional” knowledge is always in flux and adapting to a quickly changing environment. Trends of globalization, especially the globalization of plant markets, have greatly influenced how plant resources are managed nowadays. While ethnobotanical studies are now available from many regions of the world, no comprehensive encyclopedic series focusing on the worlds mountain regions is available in the market. Scholars in plant sciences worldwide will be interested in this website and its dynamic content. The field (and thus the market) of ethnobotany and ethnopharmacology has grown considerably in recent years. Student interest is on the rise, attendance at professional conferences has grown steadily, and the number of professionals calling themselves ethnobotanists has increased significantly (the various societies, like the Society for Economic Botany, the International Society of Ethnopharmacology, the Society of Ethnobiology, and the International Society for Ethnobiology currently have thousands of members). Growth has been most robust in BRIC countries. This new MRW on Ethnobotany of the Himalayas takes advantage of the increasing international interest and scholarship in the field of mountain research. It includes the best and latest research on a full range of descriptive, methodological, theoretical, and applied research on the most important plants in the Himalayas. Each contribution is scientifically rigorous and contributes to the overall field of study.




Zagros, Hindu Kush, Himalaya


Book Description

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.




Tectonics of the Himalaya


Book Description

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.




Soils in the Hindu Kush Himalayas


Book Description

This book focuses on the nature and properties of soils of Hindu Kush-Himalayas and their management for agricultural land use. It discusses all aspects of climatic variations and potential of resources in the Himalayan region including examples from Afghanistan, Bangladesh, Bhutan, China (Tibet), India, Myanmar, Nepal and Pakistan. Chapters cover the geology of the parent material of native soils, soils microbes, flora and fauna. Soil classification has been given in detail to better understand the nature of soils for judicious management strategies. The authors present land use practices and suggestions for changes in land use to benefit from the full potential of the soils in this region. Their ultimate aim is to find ways of feeding the ever-increasing population and raising the standard of life for the people living in the Himalayan mountain region.




Neotectonism in the Indian Subcontinent


Book Description

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




Crustal Architecture and Evolution of the Himalaya-Karakoram-Tibet Orogen


Book Description

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.
