- Abstract:
- This project will elucidate the thermal and rheological evolution of the crust during tectonic thickening in the hinterland of the Himalayan orogen and assess constraints on surface uplift rates. Combined field and geochemical studies of mid-Miocene granites and dykes intruding a >1000 km-long, crustal-scale antiform south of the Tsangpo suture zone will (i) provide insights into deeper crustal processes than have been deduced from the High Himalayan granites to the south, and (ii) assess the role of the controversial 'partial melt zone' in the mid-crust inferred from seismic imaging. Detailed mapping coupled with accessory-phase chronometry, Sr-Nd isotope systematics and Ar-Ar cooling age profiles will determine the source of crustal melts and the relative timing of anatexis, doming and thrusting, thus identifying the causes of magmatism in this crucial part of the collision zone.
