Abstract
Enhancement of anomaly plays such a critical role in mineral exploration that this work has been carried out by removed noise in geophysical data. Power spectrum area (S-A) and multifractal singular value decomposition (MSVD) methods are application methods in enhancement of anomaly that are usually used in the geochemical exploration process. However, these methods have not been widely used in the geoelectrical data so far. Hamyj deposit is located about 80 kilometers west of Birjand city, South Khorasan province, Iran. In this area, resistivity and induced polarization data have been surveyed by dipole- dipole array. In this paper, IP data has been inversed by the linear method. Then, enhancement of anomaly IP data has been carried out by S-A and MSVD methods. Results of S-A and MSVD methods were compared with each other. Results indicate that the S-A method has determined the location of anomaly IP data better than the MSVD method.
