The Miocene Abu Alaqa Group, exposed on the eastern side of the Gulf of Suez, contains a series of coarse-grained delta deposits located in the hanging wall of the northwest-trending East Margin fault zone. Seven major fan sequences have been identified. The first three fan sequences are aggradational and cover an area of less than 2 sq km. The sequences are dominated by pebble/boulder conglomerates, with predominantly sigmoidal, high-angle clinoforms (between 15 and 25 degrees) as much as 150 m high. These fan sequences represent talus cones and fan deltas, which were probably deposited during activity on the fault zone and are situated at transfer segments. The other four fan sequences are predominantly progradational, consisting of mixed carbonate-siliciclastic braid d ltas with local reefs. They are less than 30 m high, have low-angle clinoforms (<15 degrees), and cover an area as large as 30 sq km. These fan sequences were deposited during a phase of tectonic quiescence when sedimentary and eustatic mechanisms determined sand-body geometry. These fan deltas and braid deltas may form hydrocarbon traps in the subsurface and create localized reservoirs. The rapid facies change into basinal fines creates an excellent lateral stratigraphic seal, but vertical and lateral seals across the fault zone generally are not well developed.
