Abstract: In order to expand the application of remote sensing prospecting technology in gold prospecting,this paper takes the Zhuanshanzi area in Inner Mongolia as an example,and selects Landsat 8 OLI remote sensing data.On the basis of image data preprocessing,the regional tectonic information is enhanced by the fusion of B7B5B3 band.The principal component analysis is used to extract the alteration anomaly information through threshold segmentation.Based on the geological characteristics and remote sensing interpretation information of the region and Zhuanshanzi Gold Deposit,the prospecting indicator of gold deposits in Zhuanshanzi area is established,and 3 prospect areas for prospecting prediction are delineated.The field verification shows that there is gold mineralization in the prospect area.It is believed that the linear and ring structure and remote sensing anomaly information extraction based on OLI remote sensing images can be used as auxiliary means for gold prospecting prediction.
