Abstract

New data on five regions of western Colombia combined with available information allow us to suggest that at least five structural complexes constitute the northwestern border of South America: Quebradagrande-Alao, Arquía-Guamote, Amaime-Chaucha, Cordillera Occidental, and Panamá-Chocó. The geologic characteristics and age of these complexes support the hypothesis of the Pacific origin of the Caribbean; we propose that the origin of these complexes are related to progressive accretion of oceanic blocks against northwestern South America in the following phases: Early Cretaceous diagonal accretion of the proto-Caribbean oceanic crust with an associated volcanic arc, Late Cretaceous diagonal collision of the Caribbean plate (oceanic plateau) against northwestern South America, followed by a frontal collision during the early Tertiary.
