摘要
鉴于矿化信息在植被稀少的地区反映在遥感图像上有明显的色调异常,故而遥感在地质找矿中的应用如今越来越广泛。通过对阿尔金地区某地的ETM+图像进行一系列比值、主成分分析,提取出蚀变信息,圈定找矿金属靶区,为大规模的找矿缩短了周期。
Because in seldom vegetation areas, the mineralization information reflected in remote sensing images has obvious hue ahnormity, the remote sensing is applied in looking mine in geology more and more widely. In this paper, take for Aerjin as an example, firstly, fusing its ETM＋ image, and then making ratio-prime component analysis （PCA）, extract the mineralization information. The results have proved this method is feasible and effective in extracting mineralization information from remote sensing image.
