南黄海EY02-2孔碳酸盐含量特征与沉积物来源

Carbonate content character and Sediment source from the core EY02-2 in the southern Yellow Sea

南黄海中部泥质区EY02 -2孔柱样碳酸盐含量在0～34、55 %之间变化 ,呈现为大西洋型CaCO3 溶解旋回 ;冰后期以来碳酸盐高含量与高碳酸盐的现代黄河和废黄河物质有关 ;

The carbonate content varied from 0 to 34.55% in the column of the drilling core EY02-2, the dissolved cycle appeared to be the carbonate dissolved cycle of the Atlantic Mode. The higher carbonate content related to materials of modern and old Yellow River in the postglacial period, while the peak carbonate content related to shell fragment in the sediment during the last interglacial period.
