摘要
广西苍梧县板山金矿矿体主要产于矿区北西向断层构造破碎带中,近矿围岩为寒武系黄洞口组第三段(∈h^3)浅变质碎屑岩,近矿围岩蚀变有强硅化、黄铁矿化和褐铁矿化,属中-低温热液型矿床。鉴于板山金矿位于广西大瑶山金成矿带,矿区内Au、Ag、As、Hg等元素异常分带性好,尤其Au异常规模大、强度高,显示了该矿区有较好的金矿找矿前景。
The orebody of Banshan Cu deposit in Cangwu,Guangxi is mainly in the NW fault fracture zone of orefield.The wall rock near orebody is Cambrian Huangdongkou Formation Member 3(∈h^3)epimetamorphic clastic rock.The wall rock alteradtion near orebody is intense silification,pyritization,ferritization,which belongs to the middle-low T hydrothermal deposit.Because it is in the Dayaoshan Au metallogenesis zone,Au,Ag,As,Hg,etc anomaly zonation is good,especially the Au anomaly large scale and intensity,the Au metallogenesis conditions in this orefield are very well.
