| 摘 要： | 冷水坑斑岩银矿由斑岩岩体中心向围岩，以铁绿泥石化和菱铁矿化为主的铁质交代作用广泛发育。蚀变碳酸盐亚种为以菱铁矿为主的ＦｅＣＯ３－ＭｎＣＯ３系列，菱铁矿中含Ｍｎ高对银矿化有利。含锰菱铁矿化在外带与浅部有增高的趋势，与银铅锌矿化关系密切

| Abstract: | Ferruginous metasomatism characterized by ferri chloritization and sideritization is commonly developed from the center of the porphyry rocks to the country rocks in the Lengshuikeng porphyry silver deposit. The subspecies of altered carbonate is the FeCO 3-MnCO 3 series dominant in siderite constituent. High content of manganese in siderite is favourable to the silver mineralization.The manganese bearing sideritization in the out belt and shallow part is trending to increase,and closely related to the silver,lead and zinc mineralization. |
