Blocks diagrams showing the structural evolution of the Tabakoto deposit (not to scale). (a) Views of the three-stage structural evolution of the deposit phase by phase and relationships with the emplacement of gold-related hydrothermal features. The first stage started with folding of the metasedimentary units and the first dike generation (D_T1), which were affected by a second folding (F₂), a set of penetrative S₂ schistosity, shear zones, and mineralized V₂ veins (D_T2). These were followed by a network of conjugate faulting during D_T3. The faults were filled by mineralized V_3a veins and cross-cut by fractures and barren V_3b veins developed parallel to the shortening direction during D_T3. The second dike generation event (lamprophyre) cross-cuts previous structural features. (b) View of the entire finite deformation and related mineralization of the Tabakoto deposit. Abbreviation: F: fold; S: schistosity; V: vein.
