Abstract 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.
