| 摘 要： | 坪地钼矿位于福建武夷山五夫镇境内,由坪地、上西坑、东坑3个钼矿段组成.控矿地质条件有下元古界大金山组变质岩、晚侏罗世中细粒钾长花岗岩和南北向断裂构造.成矿可分为3个阶段,中高温热液成矿阶段形成坪地钼矿段,中温热液成矿阶段形成上西坑钼矿段.通过综合资料分析,表明坪地钼矿床成因类型属岩浆热液充填交代型钼矿床,成矿时代为晚侏罗世.

| Abstract: | The Pingdi molybdenum Deposit, located at Wufu Town, Wuyishan City, is made up of the three molybdenum allotments, namely Pingdi ore block, Shangxikeng ore block and Dongkeng ore block. The ore-control geological conditions include the metamorphic rock of Early Proterozoic, the intermediate-fine grain moyite of Late Jurassic and faulted structures of the northern and southern trend. It is considered that there are three ore-forming stages. The intermediate-high temperature hydrotherm ore-forming stage comes into be the Pingdi molybdenum ore block and the moderate temperature hydrotherm ore--forming stage takes shape of the Shangxikeng molybdenum ore block. The analysis results of the integrated data make it clear that the Pingdi molybdenum deposit belongs to the molybdenum deposit of the magmatic hydrothermal filling and metasomatic type and the metallogenetic time is Late Jurassic. |
