福建光泽崩山铅锌多金属矿地质特征及找矿前景探讨

On the Geological Characteristics and Ore-finding Perspective of the Bengshan Lead-zinc Polymetallic Deposit in Guangze County,Fujian Province

光泽崩山铅锌多金属矿产于晚侏罗世下渡组酸性火山岩及碎斑熔岩中,受北东向断裂控制。目前已发现矿体4个,各矿体呈脉状、透镜状产出,矿石主要为方铅矿、闪锌矿,与硅化、黄铁矿化关系密切,属火山构造气成热液充填型矿床。分析认为其深部仍具有较好的寻找铅锌多金属矿的潜力。

The Bengshan lead-zinc polymetallic deposit exist in the acidic rock and Porphyroclastic lava of late Jurassic Xiadu formation, which is controlled by NE-trending faults. Four ore- bodys have been discovered at present, and the orebodys act like a veiny and lenticular oc- currence. The major ore minerals are gelena and sphalenite, which is closely associated with sillica, pyrite technology. The deposit belongs to the volcano-tectonic hot fluid filling gas deposit. It is considered that there are a better looking for Pb-Zn polymetallie ore potentiality in the deep.
