Th-U variation diagrams of the mineralized silica veins at El-Missikat (a and b brecciated and massive silica veins through drift#DI and c and d brecciated and massive silica veins through drift#DII) and El-Erediya (e and f reddish silica veins through drfits# DII and DIII) discriminate between hydrothermal (2.5 > Th/U > 0.1) and supergene U-mineralization (Th/U ratios ≤ 0.1)
