FIGURE 11. Field photos showing the depositional sequences, A shows the boundary between Qurn (sequence 2) and Tarbul members (sequence 3); B shows the depositional sequence 3 representing Tarbul Member and the overlying sequence 4 of Maadi Formation; C shows shale and marly facies that represented the transgressive systems tracts of sequence 3; D shows the reefal facies with bivalvia (black arrows) that represented the highstand systems tracts (HST) of sequence 4.
