Abstract
Cenozoic continental rifting in southern East Siberia and northern Mongolia has been associated with subsidence and broadening of rift basins at the account of their mountain borders. This neotectonic trend is, however, superposed with continuous or periodic tectonic inversions in which the basin floor may uplift while marginal fault steps and saddles between basins may subside. Cenozoic geomorphic inversions are expressed in changes of river flow out of Lake Baikal.
