“…These plutons were intruded into Phanerozoic sedimentary rocks overprinted by medium-to lowgrade metamorphism, possibly also of Devonian and Permian age (McCourt et al, 1984;Vinasco et al, 2006). Magmatism associated with ongo-ing subduction of the Pacifi c-Nazca plate off the west coast of Colombia is recorded by Middle-Late Jurassic, Cretaceous, and Paleogene zircon U-Pb ages from intrusive and extrusive rocks in the Central Cordillera (Etayo-Serna et al, 1983;Aspden et al, 1987;Restrepo-Pace, 1992;Villagómez, 2010). Cretaceous zircon U-Pb ages are absent from coeval rocks from the Eastern Cordillera (Horton et al, 2010b;Nie et al, 2010;Saylor et al, 2011).…”
