... of a Famatinian arc (∼ 480 Ma) and Carboniferous–Triassic magmatism along northwestern Gondwana. Pre-Andean and Amazonian DZ likely was recycled from Paleozoic metasedimentary rocks of the Andean Cordillera and Amotape terrane, although the data do not preclude delivery of Amazonian detritus directly...

We predict that the Peru Bank (offshore Tumbes Basin) lies at the tail of the ‘Greater Panama Terrane’ and comprises Caribbean plateau basalt and overlying arc volcanic rocks rather than continental crust similar to the onshore Amotape Block (e.g...
