文摘

A set of new global plate tectonic reconstructions sheds light on the evolution of the Earth's oceans, continents, and individual terranes in the Palaeozoic-Triassic. The Greater Caucasus is interpreted as a Hanseatic terrane that separated from Laurussia in the Devonian and then collided with the Gondwana-derived Galatian Superterrane. However, this contrasts with the hypothesis according to which the Greater Caucasus Terrane is Galatian in its nature. The reasons for the interpretation of the Greater Caucasus as a Hanseatic block are unclear, and this interpretation does not explain some observations. Further research is necessary in order to understand the plate tectonic position of the Greater Caucasus Terrane in the Palaeozoic.
