In order to learn the application effect of airborne hyperspectral remote sensing data in mineral resources exploration in northwestern regions and to investigate the metallogenic geologic environment in Shijinpo of Gansu,the paper uses airborne hyperspectral remote sensing information for prospecting in the region.Shijinpo gold deposit is analyzed using airborne hyperspectral remote sensing interpretation,the characteristics of the hyperspectral remote sensing anomaly are summarized,and based on the ore-forming regularities,airborne hyperspectral remote sensing model is constructed to delineate the prospecting targets for gold polymetallic remote sensing.It is verified by outdoor investigation that hyperspectral remote sensing has prominent effect of ore guiding and revealing on many newly discovered gold and gold polymetallic mineralization clues in previously ignored primary section,providing basis for afterwards geologic applications of hyperspectral remote sensing in Shijinpo region.The study can also be used as an practical case for exploration of polymetalic deposit in other mineralization areas.
