A correlative study of two domains from Southeastern Europe Balkan and Alpine, was performed. The correlation concerns mainly their Neoproterozoic-Cambrian evolution and is stimulated by a number of similarities in both domains. The similarities include common onset of the ocean development, evolution and destruction of the ocean crust. The Balkan domain (Balkan terrane) is comparatively well preserved with well established interrelations between rock associations. The Alpine domain, composed of metamorphic rock units from the Alps basement, is intensely deformed. The study results indicate that the compared areas are composed of analogous rock associations, and different geological processes took place simultaneously, and their crust evolution terminated in a similar manner. These coincidences are notably expressed during the process of intra-oceanic arc development and during the destruction of the oceanic crust by its obduction as a result of the Ordovician orogeny. These results of the study suggest that both domains could be regarded as portions of a terrane, called here Thraco-Alpine. The Thraco-Alpine terrane is considered to be a trace of a Neoprotezoic ocean basin and could be regarded as a belt, likely the youngest peri-Gondwanan belt.
