ABSTRACT
Five (05) clay samples from Okada were investigated using X-Ray Diffractometry (XRD) and X-Ray Florescence (XRF) techniques to determine its mineralogical and geochemical composition. The geochemical analysis revealed a significant presence of SiO2 (45.87wt.%), Fe2O3 (17.41wt.%), Al2O3 (12.68wt.%) and CaO (16.38wt.%). The predominant clay minerals identified are Montmorillonite (25.48%) and Kaolinite (17.00%), while Quartz (21.80%) is the dominant non-clay mineral. The Al2O3/TiO2 ratio shows that the clays are from a mafic igneous origin and the SiO2/Al2O3 ratio show most of the clays are montmorillonitic with values ranging from 2.97 to 4.67, except for OK5 which is Kaolinitic with a value of 2.97. The results from this study suggests potential suitability for various medical application due to the presence of Montmorillonite in high amount for its adsorbent and detoxifying properties by adsorbing VI positively charged toxins to itself. However, further research needs to be carried out to understand the specific area in medicine where it has high value.
