ABSTRACT

The river bed sediments of River Forcados along Patani and environs were sampled and taken to the laboratory for bulk analysis using XRD. It was observed that the sediments were silty clay to coarse sand. The sediment colour range from brown to grey. SiO₂ was observed to be the most abundant oxide with a concentration ranging from 58.660% to 84.258% with an average of 72.955%. The sediments are enriched in the following oxides: Sio₂, Al₂O₃, Fe₂O₃, K₂O, MgO, CaO and TiO₂. Whereas, the sands are depleted in the following oxides: V₂O₅, Cr₂O₃, MnO. Co₃O₄, NiO. CuO, Nb₂O₃, MoO₃, WO₃, P₂O₅, SO₃, BaO, Ta₂O₅, ZnO, Ag₂O, Cl, ZrO₂, SnO₂. Sodium in oxide form (NaO) or elemental form (Na) is not observed because its concentration is below detection limit of 0.01%. The SiO₂/Al₂O₃ ratio and the K₂O,/NaO ratios show that the sediments are mineralogically mature and have an acidic igneous rock source.
