Potential palaeogeographic relationships. The model for the suggested position of Wechsel arc is based on the recent proposal of Haas et al. (2020) (red star) with the major difference that a West African palaeogeographic relationship for the Cambrian is preferred (yellow star) (see text for discussion). Circles indicate the Late Archean/Early Proterozoic (Eburnean) crust and Late Ediacaran/Cambrian arc systems, which extend to South America (e.g., Ribeiro belt)
