Abstract
The Tankhoi foothill plain is situated on the southern coast of the Lake Baikal, between the Lake and Khamar-Daban mountain Range. Present climate of this area is wetter and less continental than the climate of the Baikal region. Such climatic conditions provided here broad development of a wet dark-coniferous taiga forest where Siberian pine and Siberian fir are the main elements. Uniqueness of the area is emphasized also with preservation of relic plants in local vegetation. Despite of the high importance of the paleogeographical studies on the southern coast of the Lake Baikal, this area knows not so many reliably dated sedimentary records with rather high temporary resolution. Meanwhile, changes of environment during the Late Glacial and Holocene could be important for socio-cultural development in this area. The main goals of the present study are: reconstruction of environmental changes of the Tankhoi foothill plain for the last 14 thousand years, (2) identification of their causes. For this purposes we present (1) results of the palynological and radiocarbon analysis of sedimentary cores from two peatlands – Dulikha and Ochkovoe reconstruction of vegetation and climate in the Late Glacial and Holocene.
