Faculty of Earth Sciences- Department of Mineral Resources
King Abdulaziz University

Dr. Hamdy Hamed Abdel Naby Youssef holds a Bachelor's and Master's degree from the Department of Geology, Ain Shams University, Egypt. He received his PhD in geology and geochemistry from the University of Tübingen, Germany (a scholarship from the German Academic Exchange Service DAAD, 1996). He is currently working as a professor in the Department of Mineral Resources and Rocks, Faculty of Earth Sciences, King Abdulaziz University. One of the most important tasks he held in Egypt (from 2016 to 2019) was the Head of the Strategy and Partnership Building Management Center at the Nuclear Material Authority, Egypt. He taught courses in general geology, igneous and metamorphic rocks, taxonomic mineralogy, geochemistry, and principles of geochemical techniques. He has many books in the fields of general geology, mineralogy, metamorphic geology, and the geology of uranium deposits. He has published many research papers in international scientific journals in the field of geochemistry.

Evidence for Mesoproterozoic Components in the Arabian-Nubian Shield

Reviewing and summarizing the early ideas on the existence of Mesoproterozoic components in the Arabian-Nubian Shield (ANS). It sheds more light on their significance in crustal evolution of the ANS. Nowadays there is a general agreement among geologists that the late Mesoproterozoic to Cambrian period is one of the most remarkable geological record in Earth’s history. It began with the fragmentation of Rodinia supercontinent (1300 Ma and 900 Ma) and ended by the amalgamation of Gondwana supercontinent.

Uranyl minerals deposits of the Arabian Nubian Shield

Uranyl minerals deposits are found filling cavities and as surface encrustations on some crystalline rocks of the Arabian Nubian Shield (ANS). The mineral assemblages include not conclusively uranophane, kasolite, soddyite, boltwoodite, autunite, meta-autunite, liandratite, brannerite, uranopyrochlore, ishikawaite, fergusonite and betafite. Several locations in the ANS were investigated in order to identify the genetic history of these deposits.
