Abstract
The structural evolution and sequence-stratigraphic architecture of the syn-rift
Middle Miocene (Langhian) Kareem Formation were studied in the Western Sub-
Basin (WSB) of the Gulf of Suez, Egypt. Biostratigraphic data, facies interpretations,
and log data from thirteen wells were used to construct six tectono-sedimentary
scenarios and lithofacies-distribution maps, which illustrate the paleogeography
during six systems tracts. Abrupt thickness and facies changes reflect deep basins
and adjacent high-relief areas created by differential fault-block movements.
Within the WSB seven individual fault blocks record complex, tectonically
controlled deposition of the Kareem Formation, which we subdivide into two
third-order sequences. Earlier tectonic interpretations, facies analysis, and
stratigraphic correlations from individual fault blocks were used to interpret the
varying depositional settings during six systems tracts and, as a consequence, to
discern the structural evolution of the WSB during the Middle Miocene
