南黄海表层粘土组分中,按其主要粘土矿物的含量分布特征,可分为五个组合区: Ⅰ区为伊利石—绿泥石—蒙脱石—高岭石;Ⅱ区为伊利石—绿泥石—高岭石—蒙脱石;Ⅲ区为伊利石—蒙脱石—绿泥石—高岭石;Ⅳ区为伊利石—高岭石—绿泥石—蒙脱石;V区为伊利石—绿泥石—高岭石—蒙脱石。 其分布范围与沉积环境大体一致。
According to the content distribution characteristics of the main clay minerals in the South Yellow Sea surface clay component, there are five assemblages: Ⅰ area is illite-chlorite-montmorillonite-kaolinite; Ⅱ is illite- Chlorite-kaolinite-montmorillonite; Ⅲ area is illite-montmorillonite-chlorite-kaolinite; Ⅳ is illite-kaolinite-chlorite-montmorillonite; Illidite - chlorite - kaolinite - montmorillonite. Its distribution range and depositional environment are generally consistent.
