Eocene is represented by a relatively thin sequence of limestones, with marl intercalations in its upper part (Rus Formation), while the Middle and Upper Eocene are represented by thick sequences of limestones with marl and shale intercalations (Dammam Formation). both formations have a wide aerial extent in the Emirates, Qatar, and Saudi Arabia (boUkHARy & Al SHAR-HAn, 1998).
StratIgraphyThe stratigraphic section measured along Wadi Tarabat at the core of the Hafit domal structure (Fig. 2) is represented by two formations, an older Rus Formation and younger Wadi Al nahayan Formation.
