Lithospheric thinning and dynamic uplift effects during slab window formation, southern Patagonia (45˚-55˚ S)

The southernmost South America has been affected by the subduction of an oceanic seismic ridge, which began to subduct below southern Patagonia at ∼14 Ma. This scenario led to the formation of a slab window, which is still active and where hot buoyant asthenospheric mantle produced thermal anomalies and modifications in the lithospheric thicknesses. Meanwhile, from the Patagonian Andes to the Atlantic coast, an outstanding regional surface...
