چکیده
Determining geophysical anomalies from background is a fundamental process in geophysical exploration. In this paper, the threshold value for induced polarization data have been determined by concentration- area (C-A), gap statistics, probability graphs and normal distribution curves. A comparison between the determined thresholds and these methods has been carried out statistically. The fractal method (as well as the other methods) is usually applied in geochemical exploration studies but it has not been widely used in geo-electrical methods so far. In this research, this method has been successfully utilized to process IP data (separating induced polarization anomalies from the background in Hamyj copper deposit). Hamyj deposit is located about 80 kilometres west of Birjand city, South Khorasan province, eastern Iran. In this area, resistivity and induced polarization data have been collected by dipole-dipole array. Finally, it was revealed that the determined threshold by the fractal method is higher than the other three methods. Therefore, the fractal method could lead to reducing the anomaly area and decrease uncertainty significantly. The concentration-area method has determined a threshold with more reliability.
