Metavolcanic greenstone lithologies form the lower parts of supracrustal sequences, particularly in the west, but become less important in the east where the sequences are thinner, higher metamorphic grades are typical and banded iron formations

The supracrustals were probably deposited at least partly upon an older Liberian basement, but evidence for this is not conclusive..Both metavolcanic greenstone-type lithologies and metasediments occur among the Birimian sequences, the former p

Reamplification of Eluted cDNAs,dominated by clastic metasediments, but basic and ultrabasic and banded iron formation lithologies also occur. Most of the belts are probably late Proterozoic in age, deformed and metamorphosed in the Pan African (550 Ma), though some bear the imprint of a Kibaran event (.. 1100 Ma). The extensive b
