Abstract
Rocks originating during three magmatic events, clearly different in age and genesis, are present in the southeastern portian of the Sierra Nevada de Santa Marta. The first event took place during Triassic-Jurassic time, is related to the rifting process, and produced alkaline siliceous magmatism interbedded with red sediments. The second one originated later, during Jurassic time by submarine vulcanism, and its composition is basic and intermediate. The third event produced acid vulcanites - rhyolites and rhyodacites - in a wide SWW-NEE belt which outcrops from the southeastern foothills of the Sierra Nevada to extensive areas on the Serranía de Perijá; the hypothesis of its age as Cenozoic is the subject of this paper.
