| 摘 要： | 利用1997年国土资源部青岛海洋地质研究所和韩国资源研究所合作在南黄海东南侧泥质沉积区所取得的两个全取芯钻孔(SYDP102,SYDP103)资料,对SYDP103孔黏土矿物进行了专门研究.结果表明,该孔黏土矿物组合特征为伊利石-绿泥石-高岭石-蒙脱石型,其物质来源于长江、周边陆源区及相邻海域细粒物质的再改造沉积.沉积区的涡旋作用是本研究区黏土矿物沉积的动力因素.该孔黏土矿物的分布特征和含量变化,与冰消期以来的孢粉组合有明显的对应关系,反映了气候特征决定了黏土矿物的形成组合特征,并与全新世全球性四个气候期(北方期、大西洋期、亚北方期、亚大西洋期)相吻合.

| Abstract: | The composition characteristic of the clay mineral in the core SYDP103 is most of the samples consisted of illite, chlorite, kaolinite and montmorillonite, which are sourced from the redeposite of the clay mineral in the Changjiang River, surrounding terreginous materials in origin and neighbouring sea areas. The dominate dynamic is eddying motion for sediment environment of the clay mineral in the study area. The distribution characteristic and change in content of this core SYDP103 have distinct corresponding relationship with spore assemblages from the last glacial stage. It was reflected that the climate characteristic determines the composition of clay mineral, which is coincident with four climatic stages of global(Boreal period, Atlantic period, Sub-Boreal period, Sub-Atlantic period) in the Holocene. |
