Below you will find my M.Sc. thesis with as subject: Structural Geology and Tectonics of Precambrian Metamorphic rocks in the Sinai, Egypt. There are mistakes which I will correct in the near future. Figures, tables and appendices wil be added later.

The Precambrian metamorphic rocks in the Wadi Kid area show two main phases of ductile deformation. The D1 compressional phase was related to subduction in an intra-arc setting. D2 phase was a phase of non-coaxial deformation along mylonitic shearzones. These mylonites form a sub horizontal penetrative foliation and were interpreted as low angle normal detachment faults. A variety of shear indicators indicate movement of the top block to NW. Due to doming of the granites reversal of shear took place in some parts of the area. Lithology, structures and metamorphism indicates that the Wadi Kid is a core complex of late Precambrian age. Orogenic collapse was responsible for the transition from the D1 compressional phase to the D2 extensional phase.
