Abstract(s)

SUMMARY: A well preserved Cadomian basement crops out at the contact between the Ossa Morena Zone and the Central Iberia Zone near Abrantes area. The magmatic and metamorphic activity recorded in this area indicates the existence of a long‐lived continental arc (ca. 692–540Ma) with coeval felsic and mafic magmatism and a final collisional event (ca. 540 Ma). This sequence of events, as well as several tectonic and metamorphic features and well‐preserved outcrops of diverse lithologies provides unique conditions for observing and characterize the Cadomian basement. The Geological Heritage from this area has high scientific and didactic relevance, which permit to interpret the past of the Earth.
