中文摘要:
      亭贡地区位于班公湖-怒江成矿带上,是藏北地区最具资源潜力的铜金矿集区之一。通过利用多源遥感数据,提取了该区的遥感地质信息(岩石地层,线-环性构造,弱矿化蚀变),并结合已知铜、金矿(化)点的分布特征,综合分析了铜、金矿的遥感找矿规律和有利部位,发现该地区的铜、金矿化多具有一个共同点,即断裂伴中酸性岩体侵入,在遥感影像上形成“φ”字型结构,圈定了9个成矿远景区,并进行了野外验证,新发现了多处矿(化)点。
英文摘要:
      Tingong area is located in the Bangong Lake-Nujiang Mining Zone in Gaize country Tibet,it is one of the most resource-potential copper and gold mining concentration areas in northern TibetBy using multi-source remote sensing data,it extracted the remote sensing geological information (rock formation,line-ring structure,weak mineral erosion),combined with the distribution characteristics of known copper and gold mine (mineralization) points,the remote sensing rules and favorable parts of copper and gold mine are comprehensively analyzed,it also found that the copper and gold mining have a point in common:fracture accompanied by acid rock mass intrusion,and form a “φ” type structure on remote sensing imagesBased on this feature,It were delineated 9 far mineralization and mineral scenic zone that on this Based,and field verified,and many new mineral (chemical) points were found
