Preliminary balanced palinspastic reconstruction of Cenozoic deformation across the Himachal Himalaya (northwestern India)
A line-length balanced palinspastic reconstruction across the Himachal Himalaya is presented, highlighting different phases of Himalayan tectonic development: Eocene shortening of the north Indian margin, Early–Middle Miocene emplacement of the crystalline core, and subsequent growth of the range by underplating. The total preserved shortening is 518 km (72%). The reconstruction demonstrates ge...
متن کاملGenetic Issues of Some of the Non Metallic Minerals in Lesser Himalaya
A brief account of the representative and workable industrial minerals namely magnesite, talc and barite in Lesser Himalaya, is presented here emphasizing their genesis. Deposits of magnesite and talc are found associated with Neoproterozoic, plateform type, shelf-slope limestone-dolomite host rocks from inner Lesser Himalayan sequences. Field, textural, geochemical signatures and fluid inclusi...
متن کاملIntegrated tectonostratigraphic analysis of the Himalaya and implications for its tectonic reconstruction
The isotope geochronology of isochronously deposited Cambrian strata from different tectonostratigraphic zones of the Himalaya confirms new stratigraphic, sedimentological, and faunal evidence indicating that the Himalaya was a single continental margin prior to collision of India with Asia. Lesser, Greater, and Tethyan Himalaya represent proximal to distal parts of a passive continental margin...
متن کاملGeochronologic Constraints on the Tectonic Evolution and Exhumation of Nanga Parbat, Western Himalaya Syntaxis, Revisited
We examine the timing of deformation and exhumation of the Nanga Parbat-Haramosh massif in the western syntaxis of the Himalaya. This study presents geochronologic and thermochronologic data obtained from basement, shear zone, and intrusive units within the massif to reveal the Cenozoic tectonic evolution of the massif and to document the extent of the Plio-Pleistocene tectonic activity. These ...
متن کاملTiming and mechanism of the rise of the Shillong Plateau in the Himalayan foreland
The Shillong Plateau (northeastern India) constitutes the only significant topography in the Himalayan foreland. Knowledge of its surface uplift history is key to understanding topographic development and unraveling tectonic–climate–topographic coupling in the eastern Himalaya. We use the sedimentary record of the Himalayan foreland basin north of the Shillong Plateau to show that the paleoBrah...
