湖南省通道县黄垢矿区金成矿地质条件与找矿潜力分析

Analysis of gold metallogenic geological conditions and prospecting potential in Huanggou deposit area Tongdao County Hunan Province

黄垢矿区位于雪峰弧形金多金属成矿带的西南段。矿区构造活动较频繁,区域性寨牙断裂于矿区东部贯穿全区,为矿区成矿作用提供了物质来源及动力基础,其两侧的次级硅化破碎带是金矿的主要赋存部位。矿区Au、As、Sb等地球化学异常发育,异常强度较高,各元素吻合性较好,异常形态与构造展布基本相似。矿区已发现7条矿脉,以石英脉型为主,Au品位一般0.1×10^(-6)-15.0×10^(-6),最高26.9×10^(-6)。矿区找矿潜力较大。

The huanggou deposit is located in the southwest of xuefeng arcuate stucture belt-Gold polymetallic metallogenic belt.The regional Zhaiya fault runs through the whole area in the east of the mining area,which provides the material source and dynamic basis for the mineralization of the mining area.The Au,As and Sb geochemistry in the mining area are well developed with high anomaly intensity,good agreement among the elements and similar in shape and distribution of structures.Seven veins have been found in the mining area,mainly of quartz vein type.The Au grade is generally 0.1×10^(-6)-15.0×10^(-6),and the highest is 26.9×10^(-6).The prospecting potential in the mining area is great.
