Abstract part of numerous granitic rocks belonging to the group known as Younger Granites, some are mineralized and lor exhibit geochemical specialization. The petrogenetic evolution of these granitic rocks is still a matter of debate. The present work is a systematic field work and detailed petrographical, mineralogical and geochemical investigations of five mineralized younger granitic plutons and associated metasomatites. The selected granitic rocks show two distinct mineralization style. One group of granitic rocks is Sn, Be, F, Mo, bearing mineralized granite (e.g. Hornr Akarem, Mueilha, Igla), the other group is Nb-Ta, W, Sn, bearing mineralized granites e.g. Abu Dabbab & Nuweibi. |
