A regional and paleoenvironmental study on the Upper Cretaceous deposits of the Bahariy Oasis, Libyan Desert, Egypt
Abstract The Bahariya Oasis represents an anticline with a major prevailing NE-SW major fault system. The present regional geological study proved that the Earth movement has undergone large changes in the sedimentary facies as well as lateral variation in the thickness of strata. These sedimentary rocks range in age from Cenomanian to Oligocene. The chronological sequence of the studied beds as well as the structure of the oasis are dealt with. The distribution of the sediment and its faunal association in the Upper Cretaceous deposits led to the distinction of three major phases of sedimentation which are also discussed in detail.
