大同高岭岩煤矸石资源的矿物学研究

Mineralogy Research of Gangue Resource of Datong Kaolin

大同高岭岩资源赋存在C-P纪煤系地层中,主要是煤层夹矸及顶、底板高岭岩,其厚度大、分布广.其中,3-5#煤层夹矸、8#煤层底板高岭岩质量优,最具开发利用价值.通过矿物学、岩石学和地球化学研究,对大同煤系高岭岩矿物组成、化学组成,及其变化规律和成因进行了系统探讨.

Datong kaolin resource depot in C-P period coal series strata which is chief coal gripping gangue and bed s roof and floor kaolin.It is thick and has extensive distribution.3-5#coal bed grips gangue,kaolin quality of 8#coal bed floor is the best,development utility value is the greatest of all.According to research of mineralogy,petrology and geochemistry,we discuss kaolin Mineral composition,chemistry composition,and change rules and origin of Datong coal series.
