Detailed description has been given individually to the abnormal colours, lineament and circular structure and image features on the multi-geographycal information composite image. We have studied the ore control effect of circular and lineament structure to the multimetal ore, and come to the point that the Xianghualing region is a complex ore control area by circular and lineament structure.Therefore, we build a remote sensing imag model for ore field in the region.
