(a) Fabric/shear zone map of the southern West African craton after a compilation of fabric data from published geological maps and photointerpretation (Fig. 6). This new map allows refining and complementing the shear zone/fault pattern of Milési et al. (1989) and Thiéblemont (2016) (see Fig. 1 for comparison); (b) deformation provinces map of the southern West African craton based on (a). The boundary between the Guineo-Malian and the Burghana provinces in northwestern Burkina Faso (NE of Bobo Dioulasso) is not well-constrained.
