摘　　要：在北武夷篁碧——梨子坑中生代火岩区通过1∶20万铅锌银铜成矿预测优选找矿靶区后,运用“511”综合找矿方法开展异常查证、普查及勘查工作。其基本步骤为首先布置1∶50000水系沉积物地球化学测量,以分解区域异常,逐步缩小找矿靶区,查找成矿有利地段;然后布置1∶10000-1∶20000土壤地球化学测量,以发现与矿化有关的各类次生异常,并查清致矿异常源,追踪矿化线索;最后展开1∶10000-1∶25000地质填图,并施工地表槽探、浅部坑探、中深部钻探等,最终发现生米坑、蔡家坪、金竹坪等找矿前景巨大的铅锌银铜钼矿区,找矿效果显著。The 1 ： 200 000 lead-zinc-silver-copper mineralization forecast was conducted in Mesozoic igneous district in Huangbi-Lizikeng area, Northern Wuyi After optimized the prospecting targets areas, anomalies inspection, geological survey and exploration work applying the ＂511＂ synthetic prospecting methods were followed. The basic steps are follows： first we did layout of 1：50000 stream sediment geochemical survey in order to decompose the regional anomalies gradually narrowing the prospecting targets areas for finding the favorable mineralization areas. Then we conducted the 1 ： 10000-2： 0000 survey of soil geochemistry in the favorable mineralization areas in order to find all types of secondary anomalies related to mineralization. Finally we found lead-zinc-silver-copper- molybdenum mining areas of great prospects in Shengmikeng, Caijiaping and Jinzhuping. The methods we used showed notable effects in mining prospecting.
