Agustín Cardona is geologist and associate professor at the National University of Colombia in Medellín. His research is related to regional tectonics, specially the understanding of the tectonic processes that shape the Meso-Cenozoic history of Northern Andes and the Caribbean. For that purpose he integrates geochemical and geochronological data from igneous rocks together with provenance analysis of sedimentary rocks to trace long term plate tectonic modifications. For this project, he will be collaborating Christy Till and students to explore the spatio-temporal and compositional evolution of the Colombian volcanic arc and its relationship to the evolution of the Nazca plate subduction history.
