Geochemical anomalies can be used in mineral resource exploration. We demonstrate a technique for mapping anomalies. The Gangdese mineral district in Tibet, west China was chosen as a study area for identifying geochemical anomalies and predicting Cu mineral resources using sediment geochemical data. The results show that the anomalies are associated both with known deposits in the middle of the study area, but also with E—W and N——E oriented faults in the north of area. These areas should be explored for undiscovered Cu mineral deposits.
