Application of fractal method in lower threshold definition of geochemistry anomaly in New South Wales area, Australia

The paper studies application of geochemistry anomalies and the definition of lower threshold in New South Wales region, Australia. Compared with anomalies delineated by conventional method, threshold obtained by fractal method is more practical. It′s more likely to discover Cu deposit within the north-east and southern part of the study area. The method is not only applicable to Cu but also has universal meaning for other geochemical elements or geological data.
