Abstract

The sediment core from the European Basin consisting of biogcnic calcareous ooze alternating with terrigenous sediments was studied by series of methods. The absolute age was determined by means of 230Thex and J3,PaCs and radiocarbon methods. The surface water paleotemperatures by means of planktonic foraminifera complexes and oxygen iso* tope ratio in their tests were reconstructed, the relation between terrigenous and bioge* nous components was determined, etc. The 1—8 stages of the Oxygen Isotopic Scale we¬re rccognized. The fluctuations of the paleoceanographic conditions for the core region are discussed.
