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 compar...

Anomaly separation plays an important role in mineral exploration. The fractal based method presented in this study provides an anomaly separation method which accomplishes anomaly separation in frequency domain. It is based on the Fourier transformation, which can be compared to a glass prism. The prism separates light into various components, each depending on its wavelength (or frequency) content. Fourier transform can be viewed as a "mathematical prism" that separates a function into various components based o...
