Abstract
The Yaouré gold deposit is an orogenic gold deposit in Côte d'Ivoire (West Africa). We combine field-based structural geology and lithostratigraphy with U-Pb geochronology, geochemistry and in-situ ore mineral trace element and sulfur isotope analyses to document the processes leading to gold mineralisation across scale spanning grain through to regional scale. We show that: (1) mineralisation is controlled by the regional crustal architecture, (2) gold mineralisation developed through a polyphased mineralisation process with economic grade developing with fault valve behaviour in a low differential stress environment, and (3) the geochemical and isotopic footprint of mineralisation help decipher Au deposition mechanisms.
