This book addresses the geology of the entire Himalayan range in Nepal, i.e., from the Gangetic plain in the south to the Tethyan zone in the north. Without a comprehensive look at the various Himalayan zones, it is practically impossible to fully grasp the processes at work behind the formation and development of the spectacular Himalaya. However, the goal is not merely to document all the scientific ontology but rather to reveal a sound basis for the prevailing concepts. Both the early literature on Himalayan geology and contemporary trends are fully covered. For the first time, the origin, use, and abuse of common Himalayan geological terms such as the Siwaliks, Lesser Himalaya, Main Boundary Thrust, Main Central Thrust, and Tethys are discussed. The book will help readers to progress from a cognitive approach to a constructive one by linking various types of knowledge, such as seeking relations between various geological structures as well as between earlier thoughts or views and contemporary approaches.

This major review contains important new information on an area that is of considerable interests to geologists: the higher central Himalaya. Coverage includes field observations, route maps, fossil finds, stratigraphic columns, geochemical age determinations, chemical rock analyses, and recently discovered mineral deposits. Its focus on parts of the Himilayas that are not accessible to non-Indians lends it added significance, as well as the dearth of recent works on this area: the classic book by Heim and Gansser is almost 50 years old. Includes numerous illustrations.

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.

The Himalaya–Karakoram–Tibet mountain belt resulted from Cenozoic collision of India and Asia and is frequently used as the type example of a continental collision orogenic belt. The last quarter of a century has seen the publication of a remarkably detailed dataset relevant to the evolution of this belt. Detailed fieldwork backed up by state-of-the-art structural analysis, geochemistry, mineral chemistry, igneous and metamorphic petrology, isotope chemistry, sedimentology and geophysics produced a wide-ranging archive of data-rich scientific papers. The rationale for this book is to provide a coherent overview of these datasets in addressing the evolution of the mountain ranges we see today. This volume comprises 21 specially invited review papers on the Himalaya, Kohistan arc, Tibet, the Karakoram and Pamir ranges. These papers span the history of Himalayan research, chronology of the collision, stratigraphy, magmatic and metamorphic processes, structural geology and tectonics, seismicity, geophysics, and the evolution of the Indian monsoon. This landmark set of papers should underpin the next 25 years of Himalayan research.

Hardbound. During the past two decades the pace of geological work in the Himalayas has considerably increased. Of the different sectors, the Western Himalaya has been studied more extensively than the other parts. A fairly good amount of data on different aspects, viz. stratigraphy, sedimentology, geochemistry, geochronology and structure has been generated from different tectonic zones of Western Himalaya. This book compiles and synthesizes the post-1964 data of the Western Himalaya. The geology of Western Himalaya is described under a tectonic zone framework, and wherever necessary, different regions are discussed separately under each tectonic zone. A geological map of the Western Himalaya has been compiled on 1:1,000,000 scale.

Geology of the Himalayan Belt: Deformation, Metamorphism, Stratigraphy presents sophisticated metamorphic and igneous rock data across various Himalayan geographic sectors, capturing their petrography, metamorphism, structure, mineralization, and regional tectonic research. With an east-west extension of about 3000 kilometers and numerous 8000 meter peaks, the Himalayas are the most spectacular mountain ranges on earth. Since the 19th century, they have provided a testing ground of global importance for the development of geodynamic concepts, from isostasy over continental collision, to more recently, feedback mechanisms between tectonics and climate. This book collects the broad range of data that's been gathered on the Himalayas over the past 50 years, providing a comprehensive analysis and interpretation on the available data that brings the scientific community a better understanding of the geological diversity and structure of the Himalayan belt, along with new techniques that have applications in a host of global geological settings. - Features a vast amount of geological research data collected in the Himalayas over the past half century - Authored by a recognized global expert on the geology of the Himalayan belt - Presents analysis and interpretation techniques to aid scientists in conducting fieldwork and research - Provides the latest information on geodynamic concepts, from isostasy over continental collision, to more recently, feedback mechanisms between tectonics and climate

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.
