Abstract

The collision of Arabian-Eurasia continental plates in consequence of Neo-Tethys subduction, produces a zone of very complex tectonic structures in Iran. The study area is hinterland of the Zagros Orogen in central part of the Urumieh-Dokhtar magmatic arc, northeast Isfahan. Major brittle structures in the study area consists of dominant NW-SE-trending longitudinal, N-S and E-W-trending oblique faults sets. Comparison of brittle structures and mineral deposits in the area indicated that the mineralizations are mainly formed along the active tectono-magmatic arc. In the study area, NW-SE trending Zefreh fault and it’s branches faults have created a dextral horsetail splay architecture. Analysis of the lineaments interpreted out of satellite images and field observations is recognized as another technique for locating porphyry type copper mineralization. There is a close correlation between increasing the intensity of fractures and the repoted copper mineralization in the area. © 2019 Taylor & Francis Group, London.
