摘　　要：福建东部火山岩区的铜多金属矿找矿问题是福建地矿工作者长期研究和争议的热点。通过对研究区成矿地质背景、矿化蚀变特征的研究,并与紫金山铜多金属矿床的成矿地质条件和矿化、蚀变规律进行对比,发现许多区域(如平和大矾山等)具有紫金山式高硫浅成热液型铜多金属矿的成矿地质条件,存在巨大的找矿潜力。并分析了紫金山式铜多金属矿的区域成矿要素,初步建立区域成矿模式,提出了今后的找矿方向。Copper polymetallic deposit exploration problems in eastern Fujian volcanic area are of hot spots in long term research and dispute by the geological and mineral workers. According to the studies of metallogenic background and the mineralization alteration features, and comparison with the Zijinshan copper polymetallic deposit on ore forming geological conditions, law of mineraliztion and alteration, it indicates that there are same characteristics of high sulfur hypabyssal epithermal Zijinshan type copper polymetallic deposits in many areas（such as Dafanshan Pinghe county） with great prospecting potential. This paper also analyses the regional ore forming geological essential factors of Zijinshan type copper polymetallic deposit, preliminarily establishes the regional metallogenic model and proposes the prospecting direction in future.
