Abstract In order to evaluate mineral resources in Ningxia, the authors used ETM+ satellite remote sensing data to extract linear and circular structure information of Ningxia by means of manual visual interpretation and computerization. At the same time, information of iron and hydroxide radical anomalies was collected by the principal components analysis and spectral-angle mapper. In combination with regional geological structure conditions, the authors made an integrated analysis of remote sensing linear character, circular structure and distribution characteristics and anomaly information in Ningxia and its indicative significance for mineral resources. The results show that remote sensing linear structure is almost identical with regional structure distribution of Ningxia, and the remote sensing linear structure and anomaly information can be employed to act as the main forecast factors for mineral resource potential evaluation in Weining North Mountain and Helan Mountain. The identified prospecting targets have provided an ideal indicative reference for mineral exploration, and some targets has already been verified by exploration results.
