Their forecasts recommend that this advancement will lead to the formation of a brand-new Atlantic subduction zone 50 million years from now, which will consequently come down into the Earths mantle.The new geodynamic model describes the evolution of the Gibraltar subduction zone and its likely development, which will contribute to the renewal of the Atlantic Ocean flooring. The only fully developed subduction zones in the Atlantic with volcanic island arcs are the Lesser Antilles arc in the Caribbean and the Scotia arc in between the southern pointer of Argentina and the Antarctic, both formed in the Cretaceous duration. The Atlantic is therefore a distinct laboratory that allows the analysis of subduction initiation.Map highlighting the Atlantic subduction zones, the fully established Lesser Antilles and Scotia arcs on the western side, and the incipient Gibraltar arc on the eastern side. Following that, the rate of migration will choose up so that– over the following 30 million years– the subduction zone will spread out into the Atlantic in the form of a semicircle, developing a brand-new Atlantic subduction system.The design replicates the propagation of a subduction zone from a closing ocean– in this case, the Mediterranean– through a narrow oceanic passage into a brand-new opening ocean, the Atlantic.
