Abstract
Sabz-Pushan Fault Zone is chosen as a case study for deformation analysis of Zagros tear faults. This study has been shown that Sabz-Pushan Fault zone is divided into independent fault segments which present evidences of dextral shear deformation. These deformations, which have been studied in detail in this paper, include structural disturbances, changes in sedimentary basin conditions (facies changes) and Neotectonics deformations. Conclusion of this research can be extended to other Zagros tear faults, such as Kazerun, Karebas and Sarvestan fault, and then can be a suitable for better understanding of Zagros Fold-Thrust belt deformations.
