Abstract
The results of this study, when integrated with published data, indicate an evolution from primitive island arc magmas to increasingly evolved high-K calc-alkaline granitic melts as a result of crustal thickening during the Eburnean orogeny combined with fractionated crystallisation and melting-assimilation-storage-homogenisation processes. The late Eburnean tectono-thermal event between ca. 2080 and 2060 Ma is proposed as the geodynamic engine that empowered gold mineralisation in the Kédougou-Kénieba inlier.
