Abstract
The uplift history of the Tibetan Plateau remains one of most intriguing and controversial issues in the Cenozoic history of our planet, and has a significant impact on regional and global climate. Here, we report new lowerature thermochronology apatite and zircon data from the Gangdese batholith in southern Tibet. Thermal history modeling of the data show that the batholith experienced a phase of rapid Early Cenozoic cooling probably associated with exhumation resulting from the initial India-Asia's collision, but possibly also due to postarc volcanic activity in the region. The batholith, then transitioned to low erosion rates (<0.05 mm/yr) between the Middle Eocene and Early Miocene, foll..
