The opening of the Magellan Strait and its geodynamic implications
Terra Nova, 25, 13–20, 2013 Abstract The existence of a Neogene‐Quaternary rift system responsible for the opening of the eastern Magellan strait has been one of the more peculiar tectonic features of the southernmost Andes since its discovery more than a decade ago. However, until now there has bee...
