The area of the Himalayas covered by this book is virtually unknown and can only be visited by Indian nationals. The information is from terra incognita covering more than 20,000 square kilometres from the central Himalayan region with an average height of 3000 to 8000 metres. Various maps and geotraverses are published here for the first time. The stratigraphic columns have been updated and revised and the tectonic framework has also been updated.
History of geological investigations; outline of geology and stratigraphy of central Himalayan zone; tectonic framework of central Himalaya with special reference to higher zone; geotraverses through central Himalayan segment; synthesis of the problem of structural-formational zonation, thrust structures, crustal evolution and compression and history of geological development of central Himalaya; geochronology of magmatic and metamorphic episodes; petrochemistry; barite-polymetallic mineralization.
