The Research by Remote Sensing of Iron Mining Area Prediction of the Skarn Type in the Area of Xi′an Li

By using remote sensing alteration information extraction and remote deciphering,this paper analyzed the characteristics of image,liner and ring structure by extracting skarn type alteration spectrum information in Xi′an Li area,and established a new skarn type area.The evaluation of iron resources potentiality was conducted by field work and a prediction model was established based on the remote sensing alteration information anomaly and image geology characteristics in the area.
