Abstract <p>The Tunka rift valley is a south-western segment of Baikal rift zone. Its whole territory is a part of the national park of the same name. The Tunka Pribaikalye relief and its elements are the base for the inimitable landscapes of the national park. The Tunka rift system presents a uniform alternation of the following neostructural forms: tilted horsts and asymmetrical block uplifts on the northern flank; the central system of the rift valleys; and the arched uplift of the southern flank. This is a standard set of morphostructural elements for the Baikal rift system. The main morphological feature of the Tunka rift is the strong inclination of its floor, ranging from 900 m to 200 km in general elevation above Lake Baikal. Such traits of recent geodynamics as volcanism, thermal activity, and seismicity are also different from other parts of the rift zone. Thus, the Tunka depression intertwines traits most typical for neotectonic and geomorphologic structure and development of the upland grabens of the Baikal rift zone, etalon expression, making the structure suitable as a morpho- and tectonotype, and very peculiar properties, even unique ones, not discovered anywhere else within intercontinental rift systems of the Earth. This paper provides a brief overview of the general features of the geomorphological and morphotectonics structure of the Tunka Rift and the most pressing problems of its study.</p>
