摘要
本文就铁帽这一重要找矿标志所包含的矿化信息在遥感影像上的反映进行了研究，通过对其地质特征及波谱特征的综合分析，进而选择合理的影像信息提取方法，以确定铁帽展布形态、空间展布特征、边界清晰程度及分辨真假铁帽，再结合野外地质调查，以达到指导找矿之目的．
The paper discusses the reflection of mineralization in remote sensing images which gos-san contains. Through synthesizing analyisis of gossan's geological characteristics and spec-trum characteristics,correct extracting means of imaging in formation are selected accordingto the result of analysis. Sequentlally,the spreading form,the spatial spreading characteris-tics, clear extent of boundary are confirmed and the distinetion between the mineralized gos-san and the immineralized gossan can be made. Combine with the field geological inspection,the purpose of prospecting can thus be achieved.
