ABSTRACT

On the basis of available isotopic data the schist are assumed to be of two (2) types: the metasediments which are mainly found in southwestern Nigeria and the low grade schist (the younger metasediments) mainly found in northwestern Nigeria. In this research, age relationship among the schist and quartzite belts of Nigeria and perhaps the study area which is Northwestern Nigeria is unresolved, as various ages have been assigned. Paleoproterozoic was an important activity which occurred when crust was formed in Africa. It is a fact that terrains with similar chronology and geochemical features formed in different geographical areas were juxtaposed in a late orogenic activity. In that, comparisons of metasedimentary series which are schist and quartzite according to time of formation imputable to different sequences can provide a better understanding to terrain accretion models.

Key words: Proterozoic, Crust, Age, Northwestern Nigeria.
