APPLICATION OF PHASE-STATE STUDY IN GEOCHEMICAL ANOMALY EVALUATION: A case study of evaluation for Majiazi stream sediment anomaly

The anomaly of stream sediments in Majiazi area is with high strength and sensible concentrated center, but the genetic mechanism of the anomaly has not clearly recognized after a few times of anomaly inspection and investigation. The study on distribution of abnormal elements in oxide-facies, combination-facies and sulfide-facies shows that the Pb and Zn elements are evenly distributed in the rocks. The anomaly is not caused by mineralization.
