This work focuses on the weathering profile study of Okpe Schistose Rock at the Igarra Schist Belt, Edo State, Nigeria. The aim is to understand the degree of weathering which is the removal of mobile elements by meteoric water and subsequent ionic concentration of stable weathering products in schistose rock. The two methodologies applied were geotechnical and geochemical data to determine the weathering profile of four layers. The results from geochemical analysis showed that S3L3 and S4L4 have been enriched with in Al2O3, K2O, Fe2O3, and MgO, while the geotechnical data showed a highly weathered zone a layer S3L3 and S4L4 from the particle size distribution curve, specific density, bulk density, plasticity, colour index tests, respectively. In conclusion, the weathering profile of the Okpe Schist shows that it’s ionic concentration and weathering profile increases downwards which gives rise to lateritic soils that is of great economic value.
