摘　　要：宝山铜钼铅锌银矿田主要由中部、东部、西部和北部４个矿床组成，属岩浆期后高中温含矿热液接触交代矽卡岩型铜钼钨铋矿床、中低温热液充填交代铅锌银矿床。矿田围岩蚀变强烈，并与矿化关系密切，具有以岩体为中心向外呈现明显的围岩蚀变和矿化分带特征，可作为找矿的重要标志。The Baoshan polymetallic mineralization field is mainly constitued of 4 deposits, i.e.,the middle,the eastern,the western and the northern deposits,The coppermolybdenumtungstenbismuth deposit belongs to the skarn type formed from the contact replacement of the postmagmatic highmedium temperature hydrothermal solutions,and the leadzincsilver deposit belongs to the mediumlow temperature hydrothermal replacement and filling type.The alteration of wall rock is strong and bears a close relation to mineralization,and displays an obvious alteration and mineralization zoning outer from the rockbodics,which may be an important indication for exploration.
