The Birim rocks of the West African craton comprise belts of greenschist- to amphibolite-grade gneiss and schist, and subparallel basins of greenschist-grade phyllite of volcaniclastic and epiclastic origin, which were intruded by igneous rocks. The

We present the results of a field, geochemical and geochronological study of a ∼5000 km2 area of the Sirwa Window of the Anti-Atlas Orogen of Morocco. The region includes the northern edge of the Palaeoproterozoic (Eburnean) West African Craton (Ze

International audience; The Maluwe basin, north-adjacent to the Sunyani basin, is the northernmost of the northeast-trending Eburnean volcaniclastic depositories in Ghana. These basins are separated from one another by remnants of Eoeburnean crust, a

The Nampula Block covers over 100,000km2, making it the largest Mesoproterozoic crustal segment in northern Mozambique and an important component of the Neoproterozoic to Cambrian (Pan-African) East African Orogen. It is bounded in the north by the W

The Damaran metagabbro-norites and metagabbros (now hornblendite) of the mafic Audawib Suite occur as unfoliated xenoliths in the well foliated, syn-D1-intruded, dioritic Okongava Batholith. Geochemically the rocks classify as low-K tholeiitic gabbro
