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

西非克拉通的南部包括世界上最重要的古元古代金省（约10,000吨金储量）的鲍勒-莫西领地。结构，变质和地质年代学数据表明，金的矿化发生在跨越整个Eoeburnean和Eburnean造山循环的三个事件中。约旦河之间形成了欧亚造山造山带和稀少的矽卡岩型金矿床。2200和2135 Ma在反复发生的火山作用，重子现象和缩短作用期间变厚，从而使古元古代地壳变厚。约旦河之间早期的造山运动和砂金矿床形成。2110和2095 Ma在反演，变质作用以及随后的斜缩短过程中，造山带内的盆地在经过约20年的充填之后发生了倾斜。2135马。当Baoulé-Mossi区域与ArcheanKénéma-Man区域在约20世纪停靠时，此矿化过程终止。2095年。约旦河之间的造山带和较不常见的与侵入有关的金矿床之间形成。2095和2060 Ma发生在鲍乌尔-莫西地区的西部和南部走向走滑到斜滑构造，碰撞后的高K质子化和地壳返工期间。欧本金矿床包括 鲍勒-莫西（Baoulé-Mossi）域的金储量的10％，而早Eburnean和Eburnean晚期的矿床包括约。分别为50–70％和20–40％。在这里，我们强调吸积碰撞构造的有利汇合，涉及幼年地壳的形成以及长期的岩浆，变质，
