The Klarkssaiyi mining area in southern Zhaosu has harsh climatic conditions,alpine hypoxia,inconvenient transportation,deep snow cover,complex structure and rich mineral resources.It is of great significance for the future prospecting work in the study area to give full play to the unique advantages of remote sensing technology.Taking Landsat-8 OLI as the data source,based on the preprocessing,according to the mineral geological conditions of the study area and the alteration characteristics of the surrounding rocks,the principal component analysis method is used to extract the iron staining and hydroxyl alteration information.The results show that the distribution characteristics of the alteration anomaly information in the study area have certain rules,and the anomaly information is distributed in bands,which is basically consistent with the structural trend,the hydroxyl anomaly and the iron staining anomaly are well combined with high intensity.The results are well combined with the known mineralization points in the study area,which proves that the alteration information is a good prospecting indicator and has important guiding significance for the prospecting work in the study area.
