The dark grey limestone in El Galala El Qebbliay plateau, in North Eastern Desert, Egypt contains TOC (Total Organic Carbon) that ranges from 0.24 to 1.84wt.% and reaches good organic richness, geochemical analysis made for the collected samples indicated that the samples have from poor to good organic richness, with poor hydrocarbon potentiality. The kerogen type is mainly type III, or III/IV with immature thermal maturation. The presence of uranium is useful as an acceleration mineral for hydrocarbon maturation.
