| 摘 要： | 对南海中部5个沉积岩芯的粘土矿物做了定性分析和半定量估算。提出南海粘土矿物组合特征为陆架浅海型与大洋型间的过渡型,这一特征表明,南海沉积物以多源性为特征。研究指出,南海沉积岩芯中粘土矿物含量高低呈现出周期性的旋回变化,并且有可对比性,控制这种变化的主要因素是沉积过程中古气候冷暖的周期性旋回变化及其所影响的沉积环境的变化。

| Abstract: | Clay minerals in the cores from the South China Sea were qualitatively and quantitatively analyzed.The assemblage of clay minerals is a transition type from shallow seas to the ocean and shows that the sediments in the South China Sea are characterized by multi-sources.The contents of clay minerals in the cores exhibit cyclic changes from high to low or from low to high and the changes arc comparable among the cores.The factors controlling the changes of clay mineral contents are the cyclic changes of paleoclimate in the dcposirional process and the change of depositional environment affected by paleoclimate. |

| Keywords: | the South China Sea core clay minerals multi-sources of sediments change of paleoclimate |
