We report new multisystem detrital thermochronology data from the most proximal Neogene clastic sediments downstream of Namche Barwa and use a thermo-kinematic model constrained by new and published data to explore its exhumation history. We collected ten sandstone samples from three sedimentary sections close to the Siang-Brahmaputra confluence. These sections are described by Govin et al. (2018), who also determined depositional ages ranging from 0.5 ± 0.3 Ma to 10.0 ± 2.0 Ma. Provenance data indicate that the source region for these deposits included the Namche Barwa massif (Govin et al., 2018). Here we present new zircon fission-track (ZFT), muscovite 40Ar/39Ar (MAr) and rutile U-Pb (RUPb) data from these sedimentary rocks.
