Abstract

Abstract

Two cores from the Prydz Bay, Antarctica have been recorded paleoclimatic change in 15 000 years.The characteristics of the grain size,mineral composition,diatom assemblage and geochemistry are sensitive to the paleoclimatic change, and especial the Heinrich Eventaround 14.31 ka is discovered.On the basis of the above study, paleoclimatic evolution can be divided into eight stages:Ⅰ.Older Dryas,Ⅱ.Heinrich Event 1,Ⅲ.Bolling-Allerod,Ⅳ.Younger Dryas,Ⅴ.changing warm period,Ⅵ.suitable period, Ⅶ warm period,Ⅷ.cool period.
- Antarctica,
- the Prydz Bay,
