The coastal plain sand Coastal sand, Osbedoluogbeyi and Idogbo comunities along Sapele bypass in Benin Region, Nigeria were analysed for Geochemical Characterisation. Twenty-one (21) samples were collected in which 7 samples were analysed for major oxides, 7 for trace elements, and 7 rare earth elements. The samples were analyzed using X-Ray fluorescence (XRF) and inductively coupled plasma mass spectrometre (ICP-MS). The provenance from the major oxides inferred that the samples were from felsic igneous source rocks (Al2O3/TiO2: ~29.90). The source area weathering of the sand shows that the sediment has undergone substantial to intense chemical weathering (CIA ~61.40; CIW ~83.00; MIA ~41.00; PIA ~77.07). The maturityof the sand is mature (SiO2/Al2O3 ~6.22). The trace elements geochemistry also authenticates the provenance as felsic source. The outcomes from the Correlation and Chi-square of the metallic oxides indicates an enrichment of silica and depletion of other oxides as well as indicates a common source. The coastal sand is most likely to be a reservoir rock for hydrocarbon potential, if it is a petroleum system with source and trap rather than a source rock.
