Their main mineral is kaolinite, usually in pisolitic, oolitic or clasticstructure.
主要矿物是高岭石，常见豆状、鲕状和碎屑状构造。

The clastic rocks in this depression are characterized by low maturation of the mineral composition, and low maturation in structure, thus diagenesis due to burial is very strong.
该凹陷沉积的碎屑岩具有矿物成分成熟度低和结构成熟度低的特征，所以其埋藏成岩作用十分强烈。
