| 摘 要： | 矿化蚀变信息是遥感找矿重要的标志。在总结前人研究的基础上,以青海省拉陵灶火地区为实例,对经典的Crosta主成分分析方法进行改进,采用ETM+1+ETM+2、ETM+3/ETM+1、ETM+4/ETM+3、ETM+5和ETM+1+ETM+2、ETM+4/ETM+3、ETM+5、ETM+7提取铁染和羟基蚀变异常信息;通过对比,认为改进后的方法找矿效果更好,为今后该区遥感蚀变信息提取提供新思路。 |

| Abstract: | Mineralization alteration informations are the important mark in remote sensing ore-prospec- ting, extraction of remote sensing alteration informations is one of the important researches of remote sensing geology. Remote sensing ore-prospecting that based on ETM data source has experienced process of development ranging from simple to comprehensive. In order to carry out the extraction of alteration in- formations more efficiently, being on the previous researches, and taking Lalingzaohuo area of Qinghai Province as an example, the traditional Crosta PCA method is improved by using ETM＋ 1 ＋ ETM＋2, ETM＋ 3/ETM＋ 1, ETM＋ 4/ETM ＋ 3, ETM ＋ 5 and ETM ＋ 1 ＋ ETM ＋ 2, ETM ＋ 4/ETM ＋ 3, ETM ＋ 5, ETM＋7 to extract anomalies of iron stained and hydroxy alteration informations. Through comparative analyses, the improved method accesses the more efficient ore-prospecting effect, thus providing a new way to extract remote sensing alteration informations in this area for the future work. |
