Testing the rigid block rotation model in Central-Eastern Iran under active tectonic regime Ahad Nouri (18008157) Behnam Rahimi (18008160) Václav Vavryčuk (5067011) Biophysics Neuroscience Environmental Sciences not elsewhere classified Chemical Sciences not elsewhere classified Biological Sciences not elsewhere classified Cancer Central-Eastern Iran block rotation focal mechanism maximum horizontal stress strike-slip fault Central-Eastern Iran (CEI) is a strike-slip zone comprising two sets of right-lateral fault zones arranged in NNW-SSE and N-S directions. This configuration provides an opportunity to test the block rotation model within a natural strike-slip fault zone. Therefore, in this study, we apply a fault-bounded block rotation model, developed for strike-slip zones, to evaluate the compatibility of this model with the kinematics of the CEI since the Neogene. The cumulative offsets and slip rates along the block-bounding faults predicted by this model are consistent with those estimated from geological, geomorphological, and geodetic studies, at least within their uncertainties. The results show that the CEI accommodates Arabian-Eurasian convergence primarily through strike-slip faulting. Furthermore, rotation of fault-bounded blocks in the CEI can accommodate part of the convergence, while also exerting a significant influence on the structural geometry and seismicity of the region. Integrating the results of the fault-bonded block rotation model with stress analysis shows that both the orientation of the maximum horizontal compressive stress (SHmax) relative to the fault strike and the rotation of fault-bounded blocks control the sense of shear on faults in CEI. This study may help explain how large strike-slip faults can control the structural framework of a region through rotation of fault-bounded blocks. 2026-09-25T08:44:54Z Dataset Dataset 10.6084/m9.figshare.33994123.v1 https://figshare.com/articles/dataset/Testing_the_rigid_block_rotation_model_in_Central-Eastern_Iran_under_active_tectonic_regime/33994123 CC BY 4.0
