摘　　要：白腊水锡矿是骑田岭芙蓉矿田的重要组成部分,与锡矿化有关的围岩蚀变有钠长石化、绿泥石化、矽卡岩化、云英岩化、黑(绿)鳞云母化、萤石化等。以野外观观察和镜下分析为基础,结合矿体中石英包裹体的化学成分研究和绿泥石的电子探针分析结果,认为钠长石化、绿泥石化、复杂矽卡岩化和云英岩化与区内锡的成矿关系最为密切,蚀变强度与矿化强度呈正相关关系。The Bailashui mine constitute the main part of the Furong orefield in Qitianling area. Alterations related to tin mineralization in the mine include albitization, chloritization, skarnization, greisenization, lepidolitization and fluoritization. Field geological observation and microscopic identification as well as study of chemical compositions of quartz inclusion in the tin ore bodies and microprobe analysis of chlorites show that the albitization, chloritization, complicated skamization and greisenization are closely associated with tin mineralization and that the stronger the wallrock alteration, the better the tin enrichment.
