South Siberian Mountains

The South Siberian Mountains ( rus, Южно-Сибирские горы) are one of the largest mountain systems of the Russian Federation. The total area of the system of mountain ranges is more than 1.5 million km². The South Siberian Mountains are located in the Siberian and Far Eastern Federal Districts of Russia, as well as partly in Mongolia. The territory of the mountain system is one of the Great Russian Regions.

Geography

The system is composed of a number of ranges aligned in an east–west direction stretching for almost . Part of them are near the border with Mongolia and China, while others rise further north.
To the south the South Siberian ranges merge with the Mongolian and Chinese mountain chains and plateaus. In the west lies the Dzungarian Basin and to the east the Mongolian Plateau. To the north the South Siberian Mountains merge with the West Siberian Lowland and the Central Siberian Plateau, both on the Russian side. To the southeast the Baikal Range is separated from the Eastern Sayan by the Baikal Rift Zone and the Tunkin Depression. To the northeast of its eastern end the South Siberian mountain system merges with the East Siberian Mountains.''(Mountains of South Siberia)''

Geologically the mountains of the system underwent a process of rejuvenation during the Alpine orogeny. Earthquakes are common all across the area of the system.Altai-Sayan Mountain Country
(in Russian)

Owing to the mountainous terrain, large swathes of the South Siberian system are uninhabited. The main cities of the vast region are, from west to east: Krasnoyarsk, Angarsk, Irkutsk, Ulan-Ude and Chita.Google Earth
