“…2F; Table 1). Zircon U-Pb ages younger than 175 Ma are consistent with derivation from the Central Cordillera (Etayo-Serna et al, 1983;Aspden et al, 1987;Restrepo-Pace, 1992;Horton et al, 2010b;Nie et al, 2010;Villagómez, 2010). These Late Cretaceous ZHe ages from grains with zircon U-Pb ages younger than 175 Ma provide the earliest evidence for exhumation in the westernmost potential sediment source, the Central Cordillera.…”

“…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).…”

“…This result, therefore, does not support earlier models which have suggested Precambrian or Early Paleozoic ages for sedimentation and metamorphism of this sequence (e.g. Gómez et al, 2007;Nivia et al, 2006;Cediel et al, 2003;Restrepo-Pace, 1992).…”

“…Fragmentation of these terranes took place during the early Paleozoic (Cordani et al, 2005), but collisions between Grenvillian-age basement blocks and Gondwana during the aggregation of Pangea remains uncertain (Silurian-Early Devonian, Forero, 1990;Restrepo-Pace, 1992). Recently, Cardona et al (2010) based on a review geochronological data from Grenvillian basement and detrital signatures on younger Paleozoic orogens of Colombia, Ecuador and Peru, proposed that Grenville-cored massifs in Colombia, such as the Santa Marta massif were formed on the northwestern margin of the Amazonia craton, and subsequently become remobilized paraauthochtonous during younger orogens.…”
