Mineralogy, geochemistry and ore genesis of Kanawa uranium mineralization, Hawal Massif, eastern Nigeria terrane: Implications for uranium prospecting in Nigeria and Cameroon

The Kanawa area, Eastern Nigeria Terrane (ENT), located proximal to Pan-African shear zone, has U prospects with an average U concentration of ~0.1 wt%. Samples taken from the fault breccia, mylonite, cataclasite and ore zone show increasing U contents of 2.2–6.7 ppm, 4–7 ppm, 36–253 ppm, and 165–>1000 ppm, respectively. U-Pb dating of magmatic zircons from the granite hosting the U prospect yield 206Pb/238U concordia age of 603 ± 5.9 Ma...
