The key of mineralization of remote sensing technology to detect lies in the tectonic and alteration minerals information extraction.By using ETM + remote sensing image to be data source, combined with the relevant geological data through visual interpretation tectonic interpretation signs,and thterpertation of lineartectonic interpretation and circular structure interpretation in in southeastern Chongqing and analysis of the spectral characteristics of the alteration minerals in the region,for remote sensing images,the use of threshold segmentation,PCA and mask analysis were extracted by means of the study area hydroxyl alteration and iron stainingalteration information.Finally,there are 6 metallogenic prediction prospects have been determinated conbined with regional geophysical and geochemical anomalies information.
