Abstract Zhalantun area in Inner Mongolia is located in the middle part of Daxing ’ an Mountains metallogenic belt. Restricted by the thick cover and complex natural geographical conditions ， uranium prospecting degree is relatively slow. Multi-source information of ore-controlling factors for typical uranium deposits was analyzed in aerial gamma-ray spectroscopy ， geochemistry and remote sensing ， the AHP model for volcanic-type uranium deposits was constructed based on GIS ， and seven uranium prospective sectors were predicted ， and two of them are brand new target which have excellent geological conditions ， rich
prospecting clues of metallization.
