Summary:
In Yauco area, the younger complex, more than 9,000 m thick, has been divided into eight formations: Sabana Grande, El Rayo, Ensenada, Rio Yauco, Rio Loco, Rio Blanco, San German, and Jicara. Ensenada is considered to have been deposited in a southern basin penecontemporaneously with deposition of Rio Yauco and Rio Blanco formations in a northern basin. Ensenada and Rio Yauco formations overlie Sabana Grande and El Rayo formations unconformably and are separated from overlying San German and Jicara formations, at least locally, by unconformities. Age is Late Cretaceous.
