ABSTRACT
Geophysical and geological studies revealed the evolution and structural style of the Es Safya Basin in North Kordofan, Sudan. Sinistral strike-slip motion of two major fault zones (i.e. the Sodiri and Abu Harr Shear Zones) led to the development of a pull-apart graben structure. The sediments are of Late Cretaceous age and reach a maximum thickness of approx. 400 m. At some major bounding faults there are hints of later (Tertiary?) reversed faulting due to a reactivation of the Central African Fault Zone.
