Journal of Petroleum Geology, (2001) The significance of strike-slip faulting in the basement of the Zagros fold and thrust belt Khaled Hessami, HA Koyi, CJ Talbot Abstract Lateral offsets in the pattern of seismicity along the Zagros fold and thrust belt indicate that transverse faults segmenting the Arabian basement are active deep-seated strike-slip faults. The dominant NW-SE trending features of the belt have undergone repeated horizontal displacements along these transverse faults. These reactivated basement faults, which are inherited from the Pan-African construction phase, controlled both deposition of the Phanerozoic cover before Tertiary-Recent deformation of the Zagros and probably the ...
