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.

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.

The Himalayan region forms an excellent field laboratory in which to study the continuing orogenic-related processes of deformation, crustal thickening, metamorphism and melting, and foreland basin evolution. The studies that make up this volume represent all aspects of the geological sciences and have been divided into six regionally and tectonically distinct settings: Karakoram and Afghanistan; North and West Pakistan; Tethyan Himalaya; High Himalaya; Main Central Thrust Zone; Main Boundary Thrust, Lesser Himalaya and beyond.

This book helps a novice to explore the terrain independently. Geoscience fieldwork with a focus on structural geology and tectonics has become more important in the last few years from both academic and industrial perspectives. This book also works as a resource material for batches of students or geological survey professional undergoing training as parts of their course curriculum. Industry persons, on the other hand, can get a first-hand idea about what to expect in the field, in case no academic person is available with the team. This book focused on structural geology and tectonics compiles for the very first time terrains from several regions of the globe.
