摘　　要：20多年来 ,对闽北变质岩的研究 ,证实了闽北变质火山岩的存在 :早期为变拉斑玄武岩建造 ,晚期为双峰式的细碧角斑岩建造。通过变质岩时空分布规律及构造演化分析 ,将闽北变质岩地层中的矿床归纳为 3大类 ,两大不同特征的成矿系列 ,并提出找矿前景。The researches on metamorphic rocks in Northern Fujian for about 20 years give the verification of the existence of metavolcanics in Northern Fujian, The metavlocanics formed in the early stage belongs to the metatholeiite construction and the metavlocanics formed in the late stage is the spillite-keratophyre construction. Based on the space-time distribution pattern of metamorphic rocks and the characteristics of structural evolution, the deposits discovered in the strata of metamorphic rocks in Northern Fujian can be grouped into three categories and two ore-forming series of different characteristics. Finally, an ore-finding future prospect is put forward in the paper.
