Abstract :
In order to find the relationship between porphyry copper depositions with faulting systems, the Aliabad porphyry and Darre Zereshk Porphyry- Skarn ores were selected as a case studies in Uramia- Dokhtar Magmatic Belt,. In this research, discovering this correlation procedure was performed by using surface and subsurface data (i.e. drilling data as geotechnical and Cu-percentage data) from Aliabad and Darre Zereshk mine districts. The results show that RQD criteria extracted from fault zones have a good correlation with surface faults which are identified by field investigations and Remote Sensing techniques. Also, the copper enriched was observed along fault zones and therefore, the relationship between porphyry copper deposits and fault zones is approved.
