PTt evolution of Cretaceous high-pressure rocks found as fragments in a Tertiary conglomerate from the Guajira Peninsula of Colombia, record the complex multistage history of the southern-margin subduction and collision zone of the Caribbean plate and Northern South America. The metamorphic rocks include metamafites (kyanite eclogites) and metasedimentary rocks (garnet-kyanite schists, glaucophane-bearing garnet gneisses and garnet-bearing chloritoid gneisses), that represent both oceanic and continental protoliths
