Abstract
In this research, the areas for prospecting porphyry copper deposits have been introduced using airborne geophysical data (magnetic and radiometric). Magnetic anomaly boundaries have been detected using the reduction to the pole (RTP), upward continuation (with different heights), horizontal derivative (HD) and tilt angle filters to estimate approximate depth of magnetic structures. In addition, the felsic intrusives and potassic alteration zones have been determined using radiometric data and the obtained ternary map. Finally, due to genetic model of porphyry copper deposits and effective factors on mineralization and integration magnetic and radiometric data results, the Chahargonbad region has been categorized according to the priority of the porphyry copper mineralization. The most favorable areas are located in north, center and east of study area.
