Chongjiang,  a component part of the Gangdise metallogenic belt, has aroused interest among geologists for its favorable metallogenic conditions and mineral resources potentials. Geochemical information plays an important role in ore prospecting. Based on geochemical data of Majiang in Chongjiang, the authors obtained important information by applying MapGIS and MRAS to extracting geochemical information. The information obtained provides scientific evidence for further anomaly selection and anomaly investigation.
