珠江口伶仃洋表层沉积的粘土矿物

CLAY MINCRALS IN SURFACE SEDIMENT OF LINGDINGYANG BAY IN THE ZHUJIANG RIVER MOUTH

本文通过多种分析,对珠江口伶仃洋有代表性的14个粘土矿物样品进行了研究,论述了粘土矿物成分、组合类型和分布特征与伶仃洋的物质来源、动力条件及环境介质的相互关系。

Fourteen sampes of clay mineral from Lingdingyang Bay in the Zhujiang River Mouth have been analysed, Illite, kaolinite and chlorite are found to be the main clay minerals in the surface sediment, which may accordingly be divided into three mineral sections and three combinative mineral types. The three chief factors for the formation of clay mineral in Lingdingyang Bay are also studied in the paper. The elements of clay mineral, their combinative types, their distributive characteristics and their relationship with the source of matter, the hydraulic conditions and the environmental entity of Lingdingyang Bay are explained further. The trasformation and adverse trasformation of clay minerals in the estuary area with complex hydraulic conditions and changeful environmental entity result in the intergrowth of many kinds of clay mineral and forming different combinative types.
