广东英德大湾水岩头铅锌矿地质特征及前景浅析

Geological characteristics and prospect of Shuiyantou lead-zinc deposit in Dawan,Yingde,Guangdong

大湾水岩头铅锌矿区处于南岭成矿带中段,湘粤坳褶带南部,粤北山字型构造前弧西翼,区域成矿地质条件优越;在勘查区内出露一套浅海台地相碳酸盐岩地层,活泼的地球化学性质,有利于热液型多金属矿床的形成,是粤西北乃至我省有色金属矿最重要赋矿层位之一;区域断裂及褶皱构造发育,长期的构造活动为(层间)破碎带的形成、成矿物质的活化转移及后生叠加改造再富集创造有利的条件。

The Shuiyantou lead-zinc deposit in Grand-Baie lies in the middle of the Nanling Mountains metallogenic belt,the south of the Yueao fold belt in Hunan,and the West Wing of the front arc of the Yuebei mountain-type structure,the active geochemistry is favorable for the formation of hydrothermal polymetallic deposits,and is one of the most important ore bearing strata of the Non-ferrous metal deposits in northwest Guangdong and even in our province,long-term tectonic activity has created favorable conditions for the formation of interlayer fracture zone,the activation and transfer of oreforming materials,and the subsequent superimposition,transformation and re-enrichment.
