 The study assessed the age distribution of Codomian-slash-pan-African originic events in several zones of Iberian massif using detrital and inherited zircon analysis compilation, revealing a consistent pan-African 6-10-mop peak in both detrital and inherited zircons. The study suggests that the Iberian crust is likely a fragment of the pan-African origin, with a relative paleo-position between the West African Craton and the Trans-Saharan belt during the late Neoproterozoic. The closed system behavior of Stenian-tonian-detrital zircon ages in the Trans-Saharan belt suggests that this megacordillera acted as a barrier, while the opening of the system to Stenian-tonian-detrital zircon during the Ordovician indicates that the Trans-Saharan belt had already become a vast penoplane at that time.
