The results reveal that: (a) the Late Jurassic eastern Pacific region consisted of an E-dipping Andean/Cordilleran arc-back-arc system which rifted prior to inception of the Greater Antilles arc; (b) the end of E-dipping subduction and the initiation of the SW-dipping Greater Antilles island arc took place at ∼135–125 Ma and involved the transform motion of suites of Andean/Cordilleran arc rocks into the N and S ends of the Antillean arc; (c) the rocks of the present-day Dutch-Venezuelan Antilles and Aves Ridge record a different tectonic story involving a separate long-lived E-dipping Andean arc system with a polarity reversal event related to the collision of the ∼90 Ma Caribbean-Colombian Oceanic Plateau (CCOP) and (d) at ∼90 Ma, plume-related rocks were also formed on the proto-Caribbean plate between the Americas as part of an oceanic plateau distinct from the CCOP.
