“…Akoko area forms part of the Precambrian Basement Complex of Southwestern Nigeria, comprising mainly of the Migmatite-Gneiss-Quartzite Complex (Figure 3) which is of Archean -Proterozoic age averagely >2Ga [12][13], the Late Proterozoic SchistBelts [14][15] and the Older Granitoids of Pan-African age (500-750Ma) which intruded the former two units [16][17][18]. The area comprises mainly of gneisses in association with other rock types which include porphyritic granite, pegmatite, aplite, quartz vein and amphibolite.…”

“…The lithological variations of the schist belts include coarse to fine grained clastics, pelitics schists, phyllites, banded iron formation, carbonate rocks (marbles/dolomitic marbles) and mafic metavolcanics (amphibolites). References [2] and [3], based on structural and lithological associations; suggest that there are different ages of sediments. However, [4] disagree with this conclusion and show that both series contained identical deformational histories.…”

“…Ainda que a idade dos "schist belts" nigerianos seja uma incógnita (Turner, 1983;Ajibade et al, 1987), muitos deles mostram características gerais de alocação e composição, com monótonas seqüências de quartzitos, metapelitos, cálcio-silicáticas, alguns carbonatos e vulcâ-nicas subordinados, bastante semelhante (feições litológicas gerais, estratigrafia e condicionamento Tabela 1: Tabela comparativa para os principais eventos/dados geológicos e geocronológicos disponíveis (ênfase para U-Pb em zircões, dados em Ga). ----------?…”
