Geometric and kinematic analysis of faults in around of Asef Mountains, north of Shiraz (Folded Zagros Belt)

In current paper, geometrical relationship between the longitudinal faults of a zone of the folded Zagros, surrounding Asef Mountains (north of Shiraz) that follow the northwest-southeast structural trend (eg. Zarghan, Katah and Sadra faults) has been studied. A western and southern zone of Zagros Mountain Chain called folded Zagros has a length of about 1375 km and a width between 120 and 250 km. The considered area is in the north of Shiraz (Sadra city in the north and near the Zarghan city) and form a part of southeastern zone of folded Zagros. The folded Zagros is considered as one of the tectonically active regions in Iran. Asef Mountains is limited by Katah and Zarghan faults from north and by Sadra faults from south. Sadra, Zarghan and a part of Katah are the faults which passed through the Quaternary sediments, as well as form the boundary of Cenozoic units in the northern and southern slopes. All these faults are located in the same structural domains and have similar geometry and mechanics. Impacts of these faults on the RGB satellite image have been identified like three lineaments. Satellite images and field visits indicate that all these faults have dip-slip reverse component and associate with right-slip component.
