Barguzin rift valley: Sedimentogenesis and paleogeography (Baikalian area, Russia)

Research on subdivision of sediments in the Barguzin rift valley based on paleofluvial studies and paleogeographic reconstructions showed that the deposits of high terraces (VII–IV) formed mostly in alluvial-lacustrine environments, whereas the lower terraces (III–I) are essentially fluvial. The Late Cenozoic activation of the tectonic movements was marked by the rise of the Baikal Lake level and the lake water inundation into river valleys and dry depressions. During the Late Pleistocene the flood water flowed gradually, a set of low terraces being formed in the process.
