MINERALIZATION MECHANISM OF KAOLINITIC ROCKS IN CHINA'S COAL MEASURES,AND THEIR DEVELOPMENT AND UTILIZATION

Kaolinitic rocks in China's coal measures are unique in the world. They are characterized by widespread distribution, multi-staged formation, complicated genetic types, abundant reserves, and better qualities. These kaolinitic rocks constitute one of the major natural resources and non-metallic deposits, and are of important development and utilization value. In this paper, the distribution and research history of the kaolinitic rocks in Chinese coal measures are briefly introduced and the composition, texture and geological occurrence of these deposits are investigated. The genetic types of the kaolinitic rocks have been further proposed. In addition, the contributions of organisms and organic matter to the formation of kaolinites are analyzed and the mineralization mechanisms were discussed on the basis of simulation experiments with the minerals dissolved by organic acid. Finally, some critical processing technologies for the kaolinitic rocks are addressed.
