Physico-chemical and X- Ray Fluorescence (XRF) analyses was used to characterize the clay deposits from Puje ward of Wukari, Taraba State with the view to establishing its suitability for industrial usage. The physical parameters considered were moisture content, bulk density, particle density. pH and loss on ignition. Chemical analysis was performed using X-ray fluorescence spectrometry. The result of the physical analysis showed a moderate moisture content of 4.08±02%, bulk density of 1.56±16 g/cm3, pH of 7.68±01 and loss on ignition of 13.18±32%. The result of the chemical analysis showed an elemental composition in the clay samples of 54.68±12% (SiO2) > 6.50±03% (Al2O3) > 1.896±01% (Fe2O3)> 0.98±22% (K2O) as the major components while the minor components included P2O5, SO2, CaO, TiO2,V2O5,Cr2O3, MnO, CoO, CuO ,ZnO,PbO,WO3,Au2O3, Rb2O, Nb2O5, MoO2, SnO,Sb2O5and ZrO2.The results of the physical parameters were found to be within the acceptable limits in comparison with the results of WHO, APHA and US Geological Agency. Also due to the high silica content of the clay deposits as shown in the results it can be inferred that the Puje - Wukari clay deposits could be used as source of silica for the production of floor tiles, ceramics, building bricks and in the synthesis of zeolite, glass, cement, lubricants and paints.
