In his latest paper, Yuntao (in collaboration with colleagues in Australia and China) has used the apatite fission track method to reveal a Miocene phase of rapid cooling in the eastern Tibetan crust. This cooling event is attributed to synchronous river incision, consistent with regional surface uplift generated by crustal extrusion along a detachment at depth.
