Abstract:

Gouli gold deposits with complex structural features，intense magmatism，extensive deformation and metamorphism，it has the geological conditions of forming large-super large gold deposits.Based on the Quickbird，ASTER and ETM images of different resolution，we have been doing the man-machine interactive ring structural interpretation and tonal anomaly analysis.The analysis result shows that image features of typical gold deposits in the area and finds out the favorable metallogenic line-ring structures.Analysis of tone anomaly area and geochemical results concludes that its alignment is high.Finally，combining with geological data，remote sensing information and geochemical information，we have classified the target and marked out favorable prospecting area.

Key words: high-resolution remote sensing, ring structure, structural interpretation, remote sensing image, prospecting targets, East Kunlun orogenic belt
