ملخص:

The Crystalline Basement Complex In The Eastern Desert And Sinai Comprises An Extensive Zone Of Silicic Dominated Magmatism That Marks The Culmination Of The Pan African Event Of Igneous Activity .Apart Of These Intrusive Complex There Is A Group Of Post Orogenic Shallow Level Intrusions Known As Pink Or Younger Granites (Akaad And Noweir 1980) Several Small Plutons Of The Younger Granites Are Sporadically Scattered In The Eastern Desert Of Egypt. Among These Post Orogenic Granite There Are AGroup Of Small Stocks And Shallow Level Intrusions That Contain Widwe Spectra Of Ore Deposits And Mineralization The Type Of Mineralization Is Quite Different from One Pluton To Another Some Granites Are Snmineralized And Mobearing And So On .Such Discrepancies And The Erratic Distribution Of The Mineralization Regime Are Still Ambiguous. There Has Been Consierable Speculations Concerning The Origin Of The Younger Granites In The Nubian Shield Particularly Those Devoid Mineralization.
