(a) Structural pattern of the Eburnean-Transamazonian orogen. Fabrics are in black and the shear zones in red. Fabrics in Africa (adapted from Jessell et al., 2016) derive from joint interpretation of medium-wavelength (> 30 km) Bouger gravity anomaly and magnetic data in exposed and buried Archean and Birimian crust. Shear zones in the Reguibat shield (northern outcrop of the West African craton) are adapted from Milési et al. (2010); (b) corresponding tectonic model (same frame as Fig. 10a).
