Crustal evolution and geodynamic setting of the Sefwi Greenstone Belt, WAC. The Palaeoproterozoic West African Craton (2.25 - 2.07 Ga) represents one of the youngest, large provinces of juvenile crust on Earth. It displays lithological and architectural similarities to a number of late Archean Provinces, including the Abitibi-Opatica terrane, Superior Province and Karelian and Kola cratons of the Fennoscandian Shield. Forming just after the Archean-Palaeoproterozoic transition, the magmatic evolution and geodynamic setting of juvenile crust formation of the WAC continues to stimulate scientific debate.
