component may either recycled component from pre-collision event or a recycled component in the source. The ANS was subjected to intensive lithospheric delamination subsequent to slab break-off and crustal/mantle thickening result from the collision between East and west Gondwana. During the late post-collisional crustal extensional stage (590-550 Ma), the upper mantle-derived melts produced in turn as a result of decompressional melting due to erosional uplifting and consequently this alkaline/peralkaline mantle-derived melt intraplate the lower/middle crustal levels. This intraplating process is facilitated by the strike-slip faults and shear zones (e.g. Shammar shear) and consequently this melt either form A-types plutonic (i.e. the associated alkali granite) complexes or continue to arrive as shallow crustal magma to form JATV. The JATV rocks were subjected to intense faulting and shearing (i.e. belong to Shammar shear), which result in metasomatic alterations (illitization, hematitization and sericitization) along these faults and shear zones. These alteration zones contain promising source for U and Zr mineralizations, which may be formed by supergene or low-temperature post-magmatic hydrothermal phase especially along faults or brecciated shear zones, characterized by strong alteration, where the precipitation of U, Zr- bearing minerals occurred as the residual late hydrothermal fluids cool to the temperature of meteoric water.
