WebMost of the present configuration of the Northern Andes is due to Neogene tectonics. The most intense phases of deformation in the Venezuelan Andes and the Maracaibo block are linked to oblique convergence and underthrusting of the Caribbean plate in the last 10 Ma. WebA product of the Nasca plate beneath the South American plate along a convergent tectonic margin, the Andes Mountains on the west coast of South America is a topographic feature that runs parallel to the Peru-Chile trench. Notice the absence of a trench along the Atlantic coast of South America.
