Abstract

This paper introduces two methods, one is the element Concentration-perimeter and the other is power spectrum- perimeter method, for separating geochemical anomalies from background based on fractal approach. The variability of the element concentration and power spectrum as a function of perimeter from sample sites reveals two different fractal distributional patterns acting within two scale ranges. Therefore, these methods can be used to effectively separate geochemical anomalous areas from background. We compared the anomalous area created using threshold from various methods on the same data, and found that these two methods are superior to the other methods. For validation and demonstration purposes, a case study of Copper element concentration values for 107 stream sediment samples from the western Iran, Kurdistan, Shorab Hajji has been tested.
