Paleoproterozoic gold events in the southern West African Craton: review and synopsis

The southern part of the West African Craton includes Baoulé-Mossi Domain, world’s premier Paleoproterozoic gold province (~10,000 metric ton endowment). Structural, metamorphic, and geochronological data suggest mineralisation occurred during three episodes that span much Eoeburnean Eburnean orogenic cycles. rare skarn-hosted deposits formed between ca. 2200 2135 Ma repeated volcanism, plutonism, shortening, which thickened crust. Early placer 2110 2095 inversion, metamorphism, subsequent oblique shortening intra-orogenic basins filled after Ma. This episode terminated when Domain docked with Archean Kénéma-Man at Late less common intrusion-related 2060 strike-slip to oblique-slip tectonics, post-collisional high-K plutonism crustal reworking across western Domain. include 10 % endowment whereas 50–70% 20–40%, respectively. Here, we highlight favourable confluence accretion-collision involving juvenile crust formation as well protracted magmatic, deformation histories resulted in diachronous events spread over least 100 myr throughout
