Abstract
The younger granites of the studied area vary in composition from monzogranite, syenogranite to alkali feldspar granite. They exhibit silicification, kaolinitization and ferrugination as a result of the post-magmatic hydrothermal alteration. The monzogranite is traversed by quartz veins and shear zone, while the syenogranite invaded by pegmatitic bodies. Two radioactive anomalies were recorded in the shear zone, as well as, in pegmatites. Petrographic investigation, XRD analyses and ESEM examination show that, pegmatites contain apatite, bastnasite, betafite, brannerite, cassiterite, columbite, fluorite, goethite lanarkite, lepidocrocite, malachite, phlogopite, thorite and uranothorite minerals. Quartz veins exhibit goethite and hematite minerals. The identified minerals reflect the importance of the pegmatites and the shear zone for the REE.
