A field-based study was carried out on three sectors in the Qina area. A complex history of initiation, reactivation and cross-cutting of faults was concluded. Probably after the Early Eocene, a dextral movement along the NW-SE faults controlled the course of the Nile Valley. A dextral movement along N-S faults – also controlling the course of Wadi Qina – modified the NW-SE faults. Later, these two fault directions were modified by a dextral shear running in NE-SW direction. Prior to Pliocene or even earlier, all fault trends changed to normal faults; two main stages of subsidence were inferred for Pliocene times. All these fault trends are still active in the study area. Low-degree active tectonics affect Wadi Qina, and some parts of the Nile Valley are also affected by low-degree active tectonics.
