RESPONSE OF COCCOLITH RECORDS IN THE SOUTH CHINA SEA TO CARBON ISOTOPE MINIMUM EVENTS

More Information
  • 摘要: 发生在冰消期时的碳同位素低值事件是晚第四纪以来大洋碳同位素变化的普遍特征。通过对南海北部MD05-2904柱状样(19°27.32'N、116°15.15'E,水深2 066 m,岩心长度4 498 cm)930个沉积物样品中颗石藻属种鉴定,发现颗石藻主要属种Florisphaera profunda,Gephyrocapsa oceanicaEmiliania huxleyi相对百分含量与浮游有孔虫碳同位素变化具有相关性。MIS5期以来δ13C值逐渐变重,颗石藻G.oceanica含量增多,下透光带种F.profunda含量逐渐降低,海水初级生产力升高。对应3次δ13C低值期,颗石藻属种含量都发生明显变化,海水初级生产力出现峰值,说明碳同位素低值事件与浮游植物群落和海洋环境变化有密切关系,颗石藻记录能够为研究大洋碳储库的变化提供依据。
