Abstract

This study is an attempt to use closely related inter-complementary paleo-archives of a local landscape to access understanding of Late Pleistocene–Holocene environmental changes in the region. The study site is a small intermountain basin in the Sayan-Tuva Upland. Paleo-archives covering about 13 000 yrs were studied : paleosol-sedimentary sequences on a delta-alluvial fan of a small river, lacustrine sediments in bottom cores and on palsa-islands and soils of palsa-islands. Continental permafrost sub–arid/arid conditions persist in the basin within the studied period. The following sequence of environmental changes was established : 11 000 and 4 000 cal yrs BP are characterized by well balanced climatic moistening; progressive aridization started in the region about 6 200 cal yrs BP. In contemporary soils aridization is reflected in widely spread Natric features and progressive salinization
