The southern part of the Central American isthmus resulted from the subduc-tion of the oceanic Pacific plate beneath the oceanic Caribbean plate. The rise of this land-bridge from the pre-Campanian ocean floor is characterized by a Campanian to Eocene island arc stage, an Oligocene to Miocene swell stage as well as a Pliocene to Recent mountain chain stage. The present study deals main-ly with the island arc stage. The first island arcs emerged towards the begin-ning of the Late Campanian: a non-volcanic archipelagos of basaltic islands bounded by strike-slip fault scarps. Where insular shelves did exist, they were colonized by rndist biostromes; the talus originated mainly by rock-falling and avalanching. As early as at the end of the Late...
