  abstract = {{S}hear zones of the {P}aleoproterozoic {E}burnean accretionary {O}rogen ({W}est {A}frican craton) are investigated by means of large-scale structural mapping. {R}egional scale (10-100 km) mapping was based on the aeromagnetic survey of {B}urkina {F}aso and craton-scale (1000 km) mapping on a compilation of fabric data. {A}t both scales, shear zones are arranged as an anastomosed transpressional network that accommodated distributed shortening and lateral flow of the orogenic lithosphere between the converging {K}enema-{M}an and {C}ongo {A}rchean provinces. {S}tructural interference patterns at both scales were due to three-dimensional partitioning of progressive transpressional deformation and interactions among shear zones that absorbed heterogeneities in the regional flow patterns while maintaining the connectivity of the shear zone network. {S}uch orogen-scale kinematic patterns call for caution in using the deformation phase approach without considering the "bigger structural picture" and interpreting displacement history of individual shear zones in terms of plate kinematics. {T}he {W}est {A}frican shear zone pattern is linked to that of the {G}uiana shield through a new transatlantic correlation to produce an integrated kinematic model of the {E}burnean-{T}ransamazonian orogen.},
