Abstract

Abstract

The statistical results of major elements in the sediments collected from northern slope of the South China Sea indicate that the terrestrial element association are Ti,Al,Fe,K,Mn,Mg. The comparison of the Ti normalized ratios of the major elements curves (such as Al/Ti、Fe/Ti and K/Ti) and planktonic foraminifera oxygen isotopic curve are presented that, during the cooling events (Heinrich event, Younger Dryas event, PME event), the terrestrial major element ratios decreased significantly. On one side, these characteristics of major elements show that the cooling events might influence the chemical weathering intensity in terrigenous area, on the other, it also plays an obvious indication role in short time scales climate changes, which is similar to indicating large time scales climate changes．
