EVOLUTION OF THE RIFT ZONE MORPHOSTRUCTURE IN THE NORTH ATLANTIC MAGMATIC PROVINCE

Abstract

The North Atlantic region, which is located between the Charlie Gibbs Fracture Zone in the south and the Nansen Ridge in the north, has long been known as the Tule volcanic province coined after the ancient name of Iceland Island holding a central position in the province. Tule Province, ~3500 km long, was the last fragment of the continental crust in the Atlantic Ocean. In the Tertiary, the whole region underwent intense tectonomagmatic activity.
