PALEOCLIMATES AND CHRONOLOGY OF THE MIDDLE WüRM MEGAINTERSTADIAL ON THE WEST SIBERIAN PLAIN

Abstract

Three warming and two cooling episodes distinguished in the middle Würm (Karginskian in Siberia, 50–24 ka B.P.) are traced virtually everywhere and, in general, synchronously in northern Asia [1–4 and many others]. The amplitude of warming episodes is of importance for the status of this fragment of geological history. In Western Europe and North America, the warming episodes did not reach the parameters of the present-day climate, and the middle Würm–Wisconsinian is considered an interstadial virtually everywhere.
