The natural heavy mineral anomaly characteristics and ore potential analysis of the Nanling metallogenic belt in Jiangxi Pvovince

The Nanling metallogenic belt, as an important natural heavy mineral anomaly belt of such resources as tungsten, tin, and rare earth elements, is located in the southwest of Jiangxi Province. The individual mineral anomalies in the belt, occurring in complicated shapes, are significantly controlled by natural geographical conditions and have close relationship with granitic intrusions as well as mineral deposits. The combination of anomalies trends in NNE direction and is accordant with structural lineation. According to the geological conditions and combined anomaly characteristics, the anomalies can be divided into two secondary natural heavy mineral anomaly belts and fourteen ore concentration areas. The natural heavy mineral anomalies in the study area fully demonstrate the potential of the mineral resources and can serve as important anomaly information indicators for the mineral resources investigation and appraisal.
