Late Cenozoic to Present Kinematic of the North to Eastern Iran Orogen: Accommodating Opposite Sense of Fault Blocks Rotation

The opposite-sense fault block rotation across the continental strike-slip faulting plays an important role in accommodating crustal deformation north of East Iran orogen. This research constrains post-Neogene kinematics NW-SE to E-W left-lateral transpressional zones at northern termination N-S striking right-lateral Neh system Using two case studies, we analyzed Birjand splay and Shekarab transpression zone by analysis satellite images, structural features, geometry kinematics, GPS (Global Positioning System) velocities, fault- earthquake-slip stress inversion, paleomagnetic data. Our results show distinctive regions rotations with different rates. As asymmetric arc, displays a transition from prevailing right lateral shear east left middle west. In east, clockwise rotation, faults oblique reverse constitute push-ups through restraining bends. west, counterclockwise is associated duplex, pop-up, folds. suggested kinematic model reveals that consumed on vertical axis rotation. led shortening along-strike lengthening improves our understanding how opposite accommodate India- Eurasia-Arabia convergence has implications evolution intra-plate collision tectonics.
