| 摘 要： | 在给出明确的命名原则基础上，将矿床的蚀变围岩划分为五类：黄玉石英交代岩、绿泥石石英交代岩、绢云母石英交代岩、电气石绿泥石化花岗斑岩、钾长石化花岗斑岩。在平面上岩体中心部位为黄玉石英蚀变带，其两侧为绿泥石石英蚀变带；在剖面上由上向下依次出现绿泥石石英蚀变带→黄玉石英蚀变带→绢英岩化带→钾化带→（电气石）绿泥石化带。从蚀变岩石地球化学角度阐述了铜银锡各自不同的成矿部位。

| Abstract: | n the basis of giving nomenclature,the altered rocks of this deposit can be divided into five types:topaz-quartz metasomatite,chlorite-quartz metasomatite,sericite-quartzmetasomatite,tourmaline-chloritization granite-porphyry and potassifeldspar granite- porphyry.Horizontally,the topaz-quartz alteration zone is located in the central part,andthe chloritequartz alteration zone is on the both sides of it.In the vertical zone,from the up-per to below,there are following alteration zones:chloritequartz-topazquartz-sericitization- potassic-(tourmaline)chlorite.By means of geochemistry,this paper describes the differ-ent ore- forming postions of copper,silver and tin. |
