Tectonics of the Western, Sikkim and Arunachal Himalaya

Abstract

During the period 2016-2020, the Indian scientists undertook extensive research in the Himalayan Orogen, which incorporated extensive field mapping, structural analysis, geochemistry, metamorphic and igneous petrology, stratigraphy and palaeontology, Ar/Ar and U-Pb geochronology, besides low-temperature thermochronology. These activities were almost spread throughout the belt from western sector through Garhwal-Kumaon, Sikkim, Bhutan and Arunachal Pradesh. In addition, research was also undertaken using magnetotelluric methods for large-scale tectonics, seismology, paleoseismology and other disciplines, which are covered in other contributions. National laboratories have now started generating high-resolution U-Pb dates, which have been providing impetus to model Himalayan tectonics, besides modelling its Paleoproterozoic and Neoproterozoic configuration. © 2020 Indian National Science Academy.
