Soil samples in Okwuta Ibeku Umuahia were characterized for their mineralogical potentials.  X-ray diffraction was used in the mineralogical characterization. Result obtained was analyzed using Bragg-Wolf equation and International Centre for diffraction data software. Bragg’s equation was used to find the d-value corresponding to Bragg’s angles. The d-values which were obtained from samples were compared with standard values. The d-spacing for the most intense peaks in the x-ray diffraction pattern are 4.27013, 3.35360 and 1.82025Å.  The result showed that the sample contained α-quartz (SiO2) an hexagonal crystal system with Space group P3221, a (Å) : 4.9209, b (Å):4.9209, c (Å): 5.4091, alpha (°): 90.0000 beta (°):90.0000, gamma (°):120.0000, volume of cell (10^6 pm^3):113.43 , Z: 3.00 ,RIR: 2.99
