Neogene Patagonian plateau lavas: Continental magmas associated with ridge collision at the Chile Triple Junction

Extensive Neogene Patagonian plateau lavas (46.5° to 49.5°S) southeast of the modern Chile Triple Junction can be related to opening of asthenospheric "slab windowsŁ associated with collisions of Chile Rise segments with the Chile Trench at =12 Ma and 6 Ma. Support comes from 26 new total-fusio...
