Abstract:
ABSTRACTThe Hammam Faraun block is the most important tectonic blocks of the central half graben of the Gulf of Suez. The study area represents the northern part of this block with the southern part of the Gharandal accommodation zone. The present study deals witThe stratigraphic succession in the study area is a Carboniferous to Miocene Pre-rift section underlying Miocene to Recent Syn-rift and Post-rift deposits. The boundary between these two elements is marked by a major unconformity, in places associated witDetailed field analysis and mapping of the Hammam Faraun district revealed certain deformations that have been honored by gravitational tectonic. Slump structures of complex folding and faulting are found restricted to certain stratigraphic intervals thatThe northern part of the Hammam Faraun block is divided structurally into eight sub-blocks, each sub-block has characteristic structures and dip direction(s). These sub-blocks are: the Gabel Hammam Faraun-Gabel Thal, El Hagrah-El Ganobia, Wadi Thal, El GuFolding plays an important role in the deformation and their axes are oriented NW, NNE and NE. Most of these folds are plunging synclines and plunging anticlines whereas the synclines are usually longer than anticlines. The plunge angles for 42 folds wereDetailed structural analyses of the mapped area indicate that the study area has two main ridges trending in NNE and NE directions oblique to the direction of the Gulf of Suez rift. The first one, the Gabel Hammam Faraun-Gabel Thal sub-block, is structuraThis ridge separates two large Miocene basins, which have the same direction as the Gulf of Suez rift.
