Application of the singularity mapping technique to identify local anomalies by polarization data (a case study: Hamyj Copper Deposit, Iran)

Abstract

Separating anomalies plays a critical role on mineral exploration. In this paper, IP anomalies have been determined by concentration-area (C-A) and singularity methods. Then a comparison has been made between the methods. The singularity map (as well as fractal method) is usually applied in the geochemical exploration process; however, it has not been widely used in the geoelectrical methods so far. In this research, it has been successfully applied to utilize this method to process IP data (recognize anomaly induced polarization data in Hamyj copper deposit). Hamyj deposit is located about 80 km west of Birjand city, South Khorasan province, Iran. In this area, resistivity and induced polarization data have been surveyed by dipole-dipole array. Finally, according to the mentioned method, 67 % of the anomalies (singularity index) are confirmed by the concentration-area method which showed significant adaption with each other. Also, a suitable area is determined by a singularity map for drilling.
