Th-U variation diagrams of El-Missikat alteration zones at drifts#DI (a, c, e, and f assigned to brecciation, greisenization, silicification, and kaolinization) and DII (b, d, and g assigned to brecciation, greisenization, and kaolinization) discriminate between hydrothermal (2.5 > Th/U > 0.1) and supergene U-mineralization (Th/U ratios ≤ 0.1)
