Clay fraction is dominated by illite and kaolinite with small proportions of smectite , chlorite and vermiculite 粘粒组成主要为伊利石和高岭石，也有少量蒙皂石、绿泥石和蛭石。
3.
Comparing with traditional desiccant such as silica gel , the desiccant takes natural dioctahedral smectite as the noumenon of moisture absorption and refined by special technics 与传统干燥剂相比如硅胶等，该干燥剂采用天然蒙脱石矿物为吸湿本体，经特殊工艺精制而成。

The smectite - to - illite transformation has close relation with sedimentation and thermal history of basins . so illite can indicate period of oil formation . dating of authegenic illite is an important task 伊利石的形成与盆地的沉积和热演化有密切关系，它可以指示油气的形成时代，因此测定成岩伊利石的形成年龄是一个重要的课题。
6.
Clay minerals are of illite , chlorite , kaolinite and smectite assemlblage . the content of illite is very high and its crystallinity index is high too , which indicate the cool and arid climate condition in the time of sediment conformation 粘土矿物组合为伊利石、绿泥石、高岭石和蒙皂石，伊利石含量占绝对优势，其结晶度指数( hw )较高，反映东海南部外陆架粘土形成于寒冷干燥的气候环境。
