Accretionary orogens have been largely recognized along the Western Gondwana (i.e., Africa and South America) margin during the entire Paleozoic. In the case of southwestern Gondwana, Paleozoic subduction along the proto-Pacific margin gave rise to the Terra Australis Orogen, which is well-recorded in southwestern South America and southernmost Africa. On the other hand, subduction and oceanic basin opening controlled the northwestern Gondwana margin dynamics, as evidenced in northern Africa and Avalonian-Cadomian terranes of Europe. However, no clear relationships between northwestern and southwestern Gondwanan regions were so far established.
