ABSTRACT
Schistose rocks from Okene-Lokoja area, SW Nigeria, consist of quartz-biotite schist, quartz muscovite schist, amphibole schist, and quartz schist. Major element compositions (oxide wt. %) of the schists together with their trace element contents (Ba. Ce. Cr. La. Li, Ni, Rb, Sr, V, Y, Zn, and Zr) are presented. The schists (excluding the quartzitic variety) are enriched in SiO,,K,O, Rb and Ba but depleted in total Fe, O. Mno. TiO,, MgO, Ni and Zn compared with rocks of similar composition from Ilesha (SW Nigeria) and other parts of the world. Petrochemical peculiarities suggest that the quartzitić schist is derived from sedimentary rocks (arkoses and arenites) whereas the other schists (quartz-biotite, quartz-muscovite and amphibole schists) are considered to be pre-metamorphosed basic igneous rocks probably derived from magmas (with calcalkaline/tholeitic affinity) emplaced in a continental environment.
