Abstract
The Cretaceous-Eocene sedimentary sequences of the Sangdanlin section at Saga, SW Tibet, within the India-Asia collisional zone, have been studied in detail for constraining the timing of initial collision. However, the post-depositional history has not been investigated. Here, we report new low temperature thermochronology data along the classic Sangdanlin section, to reveal the cooling/exhumation history of the Indus-Yarlung suture zone (IYSZ) and northern Tethyan Himalaya. Samples from the IYSZ, all yield latest Oligocene-Miocene ages, with most zircon (U-Th)/He ages ranging between ~18 and 27 Ma and apatite fission track (AFT) ages of ~12–9 Ma. Thermal history modelling indicates a consi..
