dc.description.abstract	Eruku and its environs lie within two belts of different lithologies (Osi migmatite – gneiss complex to the west and Egbe schist belt to the east) which have been well studied. This area has remained relatively uninvestigated in terms of mineralization and hence its mineralization potential is unknown. This work therefore aims at identifying the mineralization types and also to delineate the mineralized zones in this area. In order to achieve these objectives, stream sediments sampling in Eruku and its environs was carried out. The stream sediments were collected at the confluence points of two or more rivers mostly at a depth of 20 – 25cm. The stream sediment samples were analyzed for trace and rare-earth elemental concentration using ICP-MS analytical method. The result of the geochemical analysis was thereafter subjected to multivariate statistical analysis and isograde plotting. The multivariate analysis shows a total of five factor groups. Four of the five factor groups are related to mineralization. From the dendogram, a total of six cluster groups were distinct, three of these groups are related to mineralization while the other three are considered to be product of weathering and erosion of both mineralized and barren rocks in the study area. The correlation analysis of some selected elements from the result of the geochemical analysis shows Cs, Nb, Sn, Ta, Cu, Mo, Ni, V, Zn, Co among others to be strongly correlated while Ba is negatively or not correlated with most of the elements. The isograde plots show that almost all the elements have their peaks in the south-eastern part of the study area. The conclusion drawn from the integration of the geochemical analysis, multivariate analysis and isograde plotting in this study is that the study area is mineralized with tantallite-cassiterite-columbite. These mineralizations are hosted by pegmatites that intrude the country rocks in the southeastern part of the study area. Also, these mineralisations are similar to the mineralization type in Egbe that lies to the east of the study area in terms of their host rocks and mineralization type
