The results of research on the Palaeolithic site Sedova in Irkutsk

The new paleolithic site Sedova shows paleoecological conditions and a development stage of technomorphogenesis in a final stage of Karginsky interstadial, taking a certain place in a compound of known sites of the interglacial period in Irkutsk. The terrain of a site Sedova settles down on a step slope of the right bort of the Angara's valley. The processes of destruction and redeposition of paleosoils formations, the general intensive slope movings of soils from high marks in depressings are expressed in dynamics of formation of culture-bearing sediments. The technological remains of paleolithic culture has been involved in these locomotions. The techniques of flat-faced, blade and microblade knapping are presented. Geological age of formation of culture-bearing sediments in Sedova can be defined by the end of Karginsky Interstadial (kr3) and the beginning of Sartan glaciation (sr1). The new geoarchaeological object Sedova, on the one hand, can be considered as a phenomenon with the specific features and chronology, occupying a certain niche in technocultural space of paleolith of Southern Angara Krai, with another, to be presented in a compound with known archaeological sites of Irkutsk, supplementing a consecutive chain of the ancient cultures deployed in the city territory.
