摘　　要：平果堆积型铝土矿常与红色粘土混杂在一起,多分布在农田与耕地之下。作者利用ETM+遥感影像,通过主成分分析方法成功提取了堆积型铝土矿的矿化信息,并利用提取的遥感矿化异常信息直接圈定铝土矿矿体,对平果矿区乃至桂西地区的堆积型铝土矿的找矿勘探提供了一条有效的新途径。Piugguo accumulated bauxite often mixes with the red clay and distributed under fields and farmland. The author successful extracted mineralization information of accumulated bauxite from ETM ＋ remote sensing images, through the principal component analysis method and ring directly the bauxite ores by the mineralization abnormalities extracted. This provided a new and effective ways for exploration and prospecting of accumulated bauxite in Pingguo district and west of Guangxi.
