For the purpose of improving the geological understanding of metallogenic process in the Huangshan-Jing’erquan Ni-Cu metallogenic belt and further determining the direction of exploration, the authors analyzed Ni element from geochemical data of stream sediments or debris by fractal filtering technique. The results show that the background of Ni element is high and anomalies of Ni element are weak and scattered in Tuha Basin, whereas the background of Ni element is low and anomalies of Ni element are strong and banded in Kangguer faults and the southeast part of the study area.
