The magmatisme of the Oriental Cordillera of Colombia has been put on evidence. This magmatisme is characterized by association of granites, microgranites and rhyolites. These igneous rocks are evidently the result of a reactivation of the ancient basement and are post or a-tectonic.Si mette in luce il magmatismo ercinico della Cordigliera Orientale di Colombia. Detto magmatismo é caratterizzato dalla associazione di graniti,micrograniti e rioliti. Si tralla di una evidente mobilizzazione dello zoccolo antico e le intrusioni sonopost o a-tettoniche.Cette étude a comme objet les montées de roches magmatiques hercyniennes de la Cordillere Orientale de Colombie. Les granites intrusifs sont associés à des roches sémi-profondeur (microgranites)...
