Item Open Access Stratigraphic chart of the sedimentary basins of Costa Rica, Central America(1994) Sprechmann, Peter; Astorga, Allan; Calvo, Claudio; Fernández, AlbertoCosta Rican sedimentary rocks deposited since the Campanian are subdivided into supergroups, groups, subgroups, and formations. The Curime, Boruca and Cerece supergroups are unconformity-bounded units. The preexisting number of formations is considerably reduced. The remaining rock units described in this paper are defined by their depositional environment, using differential sedimentologic criteria. The use of sequence stratigraphic terminology is discussed.Item Open Access Der älteste kalkalkaline Inselbogen-Vulkanismus in Costa Rica. Marine Pyroklastika der Formation Loma Chumico (Alb bis Campan)(1994) Calvo, Claudio; Bolz, AngelaIn diesem Artikel werden die ältesten vulkanischen Produkte des Costa-Rica-Inselbogens untersucht, die Subduktions-Prozesse am westlichen Rand der Karibischen-Platte in der Unter-Kreide belegen.Item Open Access Kretazische Subduktionsprozesse in Südzentralamerika(1998) Calvo, Claudio; Seyfried, Hartmut (Prof. Dr.)The study presents a combined sedimentological, micropaleontological and petrological approach to the Cretaceous sedimentary basement and cover sequences of the Costa Rican arc orogen. The findings show an evolved volcanic arc with explosive calc-alkaline volcanism, which was active since at least the Albian. This intraoceanic arc was built on the western Caribbean Plate boundary where the oceanic Farallon Plate was continuously subducting. Some evidence suggests that the subduction processes in southern Central America might have already begun in the Late Jurassic.Item Open Access Tectonic uplift of the Costa Rica - Panamá arc in the Paleocene time as a consequence of the collision between the Cuban arc and the Bahamas Bank(1992) Calvo, Claudio; Bolz, AngelaThe article resumes the sedimentary record in southern Central America from tectonic uplift of the Costa Rica - Panamá arc in the Paleocene time as a consequence of the collision between the Cuban arc and the Bahamas BankItem Open Access Albian to Campanian explosive island arc volcanism in Costa Rica : a new basis for plate reconstructions of western Caribbean(1994) Calvo, Claudio; Bolz, AngelaIn dieser Zusammenfassung werden konkrete Hinweise auf Subduktionsprozesse während der Unterkreide in Südzentralamerika präsentiert. Somit bildete der entsprechende mittelamerikanische Inselbogen seitdem die westliche Grenze der Karibischen Platte.
