| The Application of Fractal Filtering Technique to the Study of the Huangshan-Jing'erquan Ni-Cu Metallogenic Belt, Xinjiang |
| For the purpose of improving the geological understanding of metallogenic process in the Huangshan-Jing'erquan Ni-Cu metallgenic 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. It is a reasonable interpretation that because of Late Carboniferous-Early Permian mantle event, abundant basaltic magma erupted in the middle and southeast parts of the study area and then were eroded and transported to Tuha Basin which was a low terrain in Cenozoic, with the root of the basalt preserved. The banded Ni anomalies in the middle and southeast part of the study area are favorable places for mineral exploration. |
