摘　　要：次火山岩型铜银多金属矿床是我国东部中生代火山岩区重要的矿床类型,次火山岩发育地区是寻找该类矿床的有利地区,硅化、绢云母化、冰长石化等是重要的找矿标志,化探是寻找该类矿床较有效的方法。The subvolcanic-type copper-silver deposits are important ores in volcanic rock area in the eastern China. Distributing area of subvolcanic rocks is favorable region for prospecting. Silicification, sericitization and adularization are better guide of prospecting. Geochemical exploration is more efficient method for search the deposits.
