摘　　要：中国含煤地层中高岭岩 (土 )分布广泛 ,成矿时代多 ,成因复杂 ,储量丰富 ,质地优良 ,是一种重要的自然资源和非金属矿产 ,具有极高的开发利用价值 ,在全世界独具特色。本文介绍了中国煤系高岭岩 (土 )资源概况、研究简史 ;根据成分、结构、地质产状等特征 ,提出了中国煤系高岭岩 (土 )的成因类型 ;对生物和有机质在其形成中的作用进行了分析和探讨 ,并结合有机酸溶解矿物模拟实验对其成矿作用做了初步探索 ;最后对煤系高岭岩的某些关键性加工技术进行了简述。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.
