Short summary
The low-relief, mean-elevation Baima Xueshan massif experienced slow exhumation at a rate of 0.01 km/Myr since at least 22 Ma and then regional rock uplift at 0.25 km/Myr since ~10 Ma. The high-relief, high-elevation Kawagebo massif shows much stronger local rock uplift related to the motion along a west-dipping thrust fault, at a rate of 0.45 km/Myr since at least 10 Ma, accelerating to 1.86 km/Myr since 1.6 Ma. Mekong River incision plays a minor role in total exhumation in both massifs.
