Summary • New GPS show a pattern of discontinuous deformation from south to north across Tibet. • The thrusting slip rates on Gangdes, Banggong-Nujiang and Jinsha Suture are 6-8 mm/yr • Intra-crustal subduction along the sutures has thickened the uppermiddle crust under Tibet. • This is facilitated by continuous insertion of the Indian lower crust into the Tibetan lower curst, raising Tibet
