摘　　要：建瓯八外洋地区位于福建省重要的铜、铅、锌、金、银成矿远景区内 ,具良好的找矿前景。通过综合归纳矿区已有的地质资料 ,系统地阐述了八外洋铅锌矿区的地质和矿床特征 ,并通过区内及其外围宏观和微观信息的研究与对比 ,认为该矿床成因类型为海底火山喷发 -沉积变质 (热液改造 )The Bawaiyang area is situated at the valuable prospective metallogenic province of copper, lead, zinc, gold and silver in Fujian Province and is one of favorable ore-finding targets. Based on the analysis results of the known geological data, the paper focuses on the discussion of geological and ore-deposit characteristics of the Bawaiyang lead-zinc minefield. By means of the research and comparison of macrocosmic and microcosmic geological information in the surveyed and periphery areas, it is inferred that the Deposit belongs to the massive-sulfides-type ore-deposit formed by the submarine volcano eruptive and diagenetic metamorphism ( hydrotherm alteration).
