HOLOCENE OF THE MIDDLE TAIGA SUBZONE OF WESTERN SIBERIA ACCORDING TO PALYNOLOGICAL DATA OF THE SECTION IN THE VALLEY OF THE R. MULYMYA

The purpose of the research was a comprehensive palaeoecological study peat deposits from core in floodplain Mulymya river, reconstruction changes climatic parameters and vegetation Holocene according to spore-pollen analysis (SPA) radiocarbon dates. In course study, new data were received SPA core, provided with series AMS dates, which made it possible record transformation forest formations Konda left-bank middle taiga province for period 10180–2720 BP / 8463–977 BC. late glacial (up 10,000 8250 BC), territory represented open spaces widespread permafrost. Early Holocene, 9750–8200 7750–650 BC, expansion woody began: there an areas sparse forests closed forests. From beginning, grew islands spruce admixture larch birch moss-shrub cover. Pine dominated composition by Middle spruce, larch, fir Siberian cedar found admixtures. instability climate is reflected variegated stratigraphy deposit: alternation sedge-cotton grass participation sphagnum mosses indicates hydrological regime fluctuations. Late (from 4760–3670 2850–1650 BC) characterized relatively stable conditions; spruce-cedar-pine under consideration. communities associations. 3670 2900 1650–1100 ВС, afforested, indicated remains wood peat.
