- The processing techniques of coal series kaolinite are introduced.
- The age of Coal Series and its overlying Red Beds of Yunnan and szechuan has been aconflicting problem for almost half a century.
- Shanle oilfield is an ultra-low permeability coal series interbred reservoir in Tuha field with special geologic condition and complex structures.
- The research reported in this paper, has provided a new industrial application for Anyang coal series kaolinite with high ironcontent.
- According to research of mineralogy, petrology and geochemistry, we discuss kaolin Mineral composition, chemistry composition, and change rules and origin of Datong coal series.
- On thebasis of describing mineralogy characteristics such as combination electron minro-form, crystallinity of clay minerals, the relationship between coal series clay minerals in theMesozoic Era in Ningxia Area and coal metamorphism was analyzed.
