Ladoga transgression and landscapes of the Holocene second half in the Southern Ladoga area (according to the study of the archaeological site Podolje-1)

Abstract

In Southern Ladoga area, we studied the new archaeological site Podolje 1, located 4 km from Lake Ladoga. Studies included archaeological, lithological, geochemical, pollen, botanical, diatom and radiocarbon analyzes. As a result, new data were obtained that specified the development of the Ladoga transgression in the second half of the Holocene in the Southern Ladoga area. The dependence of the formation of cultural layers on changes in the hydrodynamic conditions of its existence is established. The lower cultural layer was formed before the beginning of the Ladoga transgression. The upper cultural layer was formed after the transgressive stage. At absolute elevations from 10 to 12 m above Sea level in the Southern Ladoga area from 6480 to 4446 cal. BP peatlands were formed. In this case, 64805944 cal. BP there was a period of some humid climate. 45344446 cal. BP, the beginning of the Ladoga transgression is recorded on the territory of the site. The completion of the Ladoga transgression was marked at the beginning of the Subatlantic period.
