摘要

我国新疆—甘肃境内的北山裂谷位于重要的金、铜、钼、铁等多金属矿产成矿带内,具有较大的成矿潜力。为更好地发挥遥感技术在该地区蚀变信息提取和找矿预测中的作用,选取成矿带西段红十井地区和磁海南一带为研究区,利用传统主成分分析法和波段比值法提取与金矿有关的羟基异常、碳酸根异常和铁染异常。但是,受区域变质作用影响,提取的异常中存在大量干扰信息。针对此问题,通过波段运算成功去除了多数干扰信息,筛选出的异常区与已知矿点具有较高的吻合度。在磁海南一带利用该方法筛选蚀变异常,经野外验证在异常区内发现2处金矿,因此认为该方法在北山地区寻找韧性剪切带型金矿的工作中具有重要先行指导意义。

Abstract：

The Beishan rift is an important metallic zone in China. The principal analysis component (PCA) technique and band ratio were used to extract alteration information related to gold deposits in the study areas in Hongshijing region and south of Cihai region lying in the west of Beishan rift. As a result of regional metamorphism, the alteration zones extracted by PCA and band ratios contain a great deal of interference information. With the method proposed in this study, most useless alteration information was eliminated and the gold deposits were located at or near the selected alteration areas in Hongshijing region. To prove the capability of this method, the authors validated the selected alteration areas south of Cihai region by fieldwork and found two gold ore spots. It is concluded that this method is effective in eliminating useless alteration information and thus is recommended for application in similar geological settings in Beishan rift.

Key words： ASTER data Beishan rift selection of alteration zone gold deposit
