Structure roles for the localization of metasomatite uranium deposit type at Wadi Belih area, Northern Eastern Desert, Egypt

Due to the resulting younger extension NW-SE event the hydrothermal solution gradually migrates upward forming alkali metasomatite, contemporaneous with uranium mineralization. They are developed along that shear zone where structure contact and the low-stress regions in the vicinity of the shear zone are favorable locations for fluid flow focusing and hence U mineralizations occur in the highly fractured and mylonitized zones along the contact as lensoidal bodies.
