This book studies the structural setting and the tectonic evolution of the Upper Cretaceous-Lower Tertiary sequence in the area west of Esh El Mellaha range, Eastern Desert, Egypt. The study also determines the relation between different stages of deformation which had affected the area.The integration between surface and subsurface studies has revealed that the basin is subdivided into four major domains dissected by three accommodation zones. The main structural system controlling the area is trending NW-SE and NNW-SSE which are related to the Clysmic event (the rifting initiation). Then followed by a sequence of events resulted in the present geology of the area, which are discussed in details.
