Abstract: Potash micatization is one of the main hydrothermal alteration minerals genetically related to the lead-zinc-silver deposit. It usually shows as muscovitization, sericitization and illitization. This paper presents a comprehensive study on the chemical composition of potash mica, adapted the follow methods: electronic probe, differential thermal analysis, X-ray diffraction analysis. At last, the structu ral characteristics and the geological environment of potash mica forming have been discussed.

Key words: potash mica, polytype, Caijiaying, lead-zinc-silver deposit

摘要: 钾质白云母是铅锌银矿床中的主要热液蚀变矿物,通常表现为白云母化、绢云母化、伊利石化。系统地研究了钾质白云母化的矿物组成,采用了电子探针、差热分析、X射线分析等技术方法,探讨了钾质白云母的结构特征和形成的地质环境及找矿意义。
