摘要
叶坑铅锌银矿位于浦城—建阳多金属成矿带与浦城-宁德钼多金属成矿带交汇处,矿体赋存于北西向断裂破碎带中,为岩浆期后中(低)温热液脉状矿床,控矿的北西向断裂带是多期次构造活动的产物,其性质大致由压扭性-张性演变,主成矿期为燕山晚期,叶坑周围尚有较大的找矿远景。
The Yekeng led-zinc-silver deposit is situated on the intermediate section of the Pucheng-Jianyang polymetallogenic belt and the Pucheng-Ninde molybdenum polymetallogenic belt. The orebody consists in the rupture zone of the northwestern faults. It belongs to the intermediate （low）temperature hydrothermal vein deposit of the magmatic post-stage. The northwestern faulted zone controlling the ore deposit is the product of multi-stage tectonic activities, which is characteristic of the evolution from compresso shear to tensional condi- tions. It is in{erred that the main metallizing phase is the late stage of Yanshan Period. It is considered that it is better for hunting for minerals in the periphery of the Yekeng area.
