摘　　要：福建永定县大排矿区是历经多次地质工作的老矿区,之前仅作为一个小锰矿在开采。本项目成功运用新理论正确指导找矿、运用新方法实施找矿,发现并基本查明该矿为一以铅锌矿为主,并共、伴生铁矿、铜矿、钼矿、银矿、锰矿等多种矿产的大型多金属矿床,矿种为浅部铅锌多金属矿经铜多金属至深部磁铁矿,成因类型为层控-矽卡岩型→层控-热液叠加改造型,该矿床的发现进一步丰富了区域矿床成因理论,拓展了区域找矿思路。Dapai old mine in Yongding county, Fujian Province, is a small-sized manganese deposit that has experienced many geological works. In this project, new theories and new methods were employed to guide the exploration work, and a large-scale lead-zinc polymetallic deposit was found accompanied by iron, copper, molybdenum, silver, manganese and so on. The mineral composition includes lead and zinc in the top, copper in the middle, and magnetite in the bottom. The genetic types change from strata bound-skarn type to strata bound- hydrothermal superimposed deformation type. The discovery of this deposit further enriches the genetic theories of regional ore deposits, and expands the way of regional prospecting.
