The present volume presents the latest contributions to the geoscientific cooperation project between the Egyptian Geological Survey and Mining Authority (EGSMA), Cairo, Arab Republic of Egypt, and the Geologisch-Paläontoloplsches Institut (GPI), Ruprecht-Karls-Universität, Heidelberg, Federal Republic of Germany. This International cooperation project is sponsored by the Federal Ministry for Education, Science, Research and Technlogy (BMBF), Bonn, through the International Bureau of Forschungszentrum Jülich. The overall objectives are to assess the structural and tectonic evolution, orogeny and terrane boundaries with particular emphasis on thelocation, nature and geometry of ore deposits. Ultimately, these cooperative efforts should lead to the comprehensive assessment and effective mining of economic minerals. The cooperat ion project has also turned attention to the very low-grade metamorphic rocks of the Hammamat Group and adjacent low-grade volcano-sedimentary sequences which host a number of important mineral deposits. These rock associations represent late-Pan-African molasse-type deposits and associated igneous rocks, which probably represent the late-tectonic stage of extensional collapse. Consequently, the Hammamat Group is represented by thick, coarse clastic sequences fining upwards into arkoses, sandstones, siltstones and mudstones. These rocks are usually conside red as being deposited in discrete sedimentary basins, commonly referred to as Hammamat Basins.
