Abstract:
We investigated the evolution of the southwestern wall of the Baikal Rift Zone (BRZ) based on the seismic structure of the sedimentary cover beneath Lake Khubsugul (Mongolia), a marginal member of the BRZ. The Khubsugul Depression formed along the boundary between the Riphean Tuva–Mongol microcontinent and the Early Paleozoic mobile zone. The Khubsugul Depression is a semigraben with steep western and gentle eastern walls. At present, the depression represents a lake with an average depth of approximately 140 m.
