The land of Egypt is part of the arabo-nubian massif which is part of the African shield or carton which in turn was an integral part from the super continent Gondwanaland, thus it has a complicated geological history.
According to Professor Rushdie said:
|Its head lines can be simplified in the reaction between the the mass land of Egypt in the south and the thetys sea the ancestor of the Mediterranean in the north across millions of years beside the changes of climatic conditions during that time.
It’s estimated that the western desert of Egypt was elevated from the under the sea some 40 million years ago forming a great tableland of limestone beds.
After the emergence occurred the great tectonic event of continental dimensions that elevated the red sea mountain range and separated Africa from Asia.
This event affected the climate bringing great rains which formed an extinve drainage system, the remains of this system is the delta of fayum region.
Some 6 million years ago the Mediterranean was isolated then desiccated .the new lowered base level of the sea had subjected Egypt to intense erosion; the modern Nile valley was excavated .active erosion caused the levelling of the sandstones plains of the Desert and the excavation of kharga and dakhla.
