During the latest Cretaceous to the Present, the Antilles volcanic arc, built upon the Caribbean plate, migrated southeastward and collided obliquely with South America. This collision resulted in the diachronous accretion of allochthonous terranes as well as diachronous formation of a fold and thrust...
