... and are characterized by numerous flat-topped peaks over 3000 m in elevation. The timing of Hangay Mountain uplift is poorly constrained, and it is not yet clear if the volcanism and uplift were related. Cenozoic volcanic rocks extend northward through the Selenga Basin into the Hovsgol rift zone, which is the southern...

.... Correlation of this erosion surface with counterparts in the basins south and west of the Hangay Mountains suggests ∼2000 m of surface uplift. At present, there are no firm data on the duration and timing of this uplift, though an increase in clastic sedimentation in surrounding basins in the mid-Oligocene...

.... In general, atmospheric and surface water play a bigger role in the development of the present-day Mongolian plateau than for the Tharsis bulge, as evidenced by highly developed drainages and thick accumulation of sediments in the basins of the Baikal rift system. On the Tharsis bulge, however, water appears...
