For the purpose of understanding the performance of the high resolution satellite image in the geological prospecting field and finding out the metallogenic geological environment of Hongshan Region in Gansu Province, the authors interpreted the ore-controlling strata, structures and rock masses in Hongshan Region by using the Gaofen-1 satellite(GF-1)remote sensing images. On the basis of reviewing and summarizing the results of previous studies and field verification, the geological characteristics and metallogenic regularity of Hongshan Region were analyzed comprehensively, the geological bodies closely related to the polymetallic deposit were summarized, and the GF-1 image interpretation keys of the important ore-controlling strata, ore controlling structure and ore rock were established. Based on the analysis of metallogenic geological characteristics and metallogenic regularity of the important ore-controlling geological units, the authors analyzed and excavated the characteristics of the ore-controlling geological factors of typical ore deposits, integrated the geological environment of the typical ore deposits and ore-controlling information; the multi-source anomaly characteristics of the typical polymetallic deposit were comprehensively analyzed, and the ore-prospecting model was established. The remote sensing prospecting was carried out, and the favorable areas for prospecting were delineated. Copper, molybdenum, iron, zinc and other metal mineralization clues were newly discovered through the field investigation, which are located in the important ore- controlling geological units according to the GF-1 image interpretation, and the better results of prospecting were achieved. The results show that the domestic satellite data can obtain good application results in the field of geological mineral exploration.
