Jurassic-Paleogene Igneous Activity at the Southern End of the Caribbean Plate in Northern Colombia

Emplacement of intrusive and extrusive bodies at the south end of the Caribbean plate in northern Colombia, since the early Jurassic, records the different tectonic settings that typify two stages of Caribbean plate evolution. The initial stage, characterized by extensive tectonism, is recorded by the Ipapure Rhyodacite, a volcanic extrusive body produced by explosive volcanism during the Early Jurassic. Later, the ongoing tectonic activity favored the emplacement of plutonic bodies during Late Jurassic. As a result, two bodies, mainly granodiorites and tonalites and locally diorites, were emplaced (Siapana Granodiorite and Cosinas Tonalite). The first stage ended with an increase in explosive volcanic activity during Early Cretaceous (La Teta volcanism). The final stage, related to low angle subduction of the Caribbean plate below the South American plate during the Paleogene, is documented by the northernmost intrusive reported in South America (Parashi Quartzdiorite).
