| 摘 要： | 矿区高岭土严格受岩性和地层层位控制。矿石含矿率高。质量好，矿物组成主要为高岭石和石英，其次有伊利石，高岭石为自形的假六方片状晶体，有序度高，晶体粒度细，伊利石多属边界圆滑的等度片状晶体。矿床的形成经历了原始的沉积阶段和成岩改造阶段，为“沉积改造”成因。

| Abstract: | The orebodies are controlled strictly by lithologic character and stratigraphic sequence.The ores are composdeof Kaolinite,quartz,illite and other minerals,and has high kaolinite content.Crystal form of the Kaolinite is Pseudo-hexagonal lamella.The kaolinite has high crystallinity and fine grain size.Crystal form of the illite is lamella that resem-bles round and has smoothedge.Vndergoing through the initial sedimentary stage and the diagenetic transformationstage,the present industrial ore deposit was formed. |
