| 摘 要： | 本文通过对铁炉坪银、铅矿床围岩蚀变的研究，划分出６种基本蚀变类型，３种蚀变带。各蚀变带以矿体为中心对称分布，各带之间呈渐变过渡关系。并指出由蚀变作用引起围岩化学成分及微量元素含量的变化，岩石化学成分与矿物成分变化相一致，成矿与围岩蚀变相辅相成。还指出了围岩蚀变的找矿意义。

| Abstract: | Based on the studies of wallrock alteration of the Tieluping Ag-Pb deposit,three alterationbelts and six alteration types have been divided.Each alteration zone distributed symmetricallytaking orebody for the zonal centre,and to the relations of gradual change and transition amongthe each zone.Author points that the alteration led to the changes of the chemical composition ofthe wallrock and the changes between chemical composition and mineral composition of the rocksare identical, and the relation between mineralization and alteration is complement each other.Author also points that the wallrock alteration has the significance for the prospecting. |
