Stratigraphy
Geological group:Cabo Blanco Formation:Playa Grande Member:Catia
Stratigraphic resolution:bed
Stratigraphy comments: The Playa Grande Formation consists of a variegated assemblage of rocks and atarts at the base with a brown conglomerate. It attains a maximum thickness of 65 ft at its type locality. The deposit is lenticular lying with a pronounced unconformity on the Las Pailas Formatiion. The Catia Member is exposed north of the Bruscas Fault. The Playa Grande and Mare formations of the Cabo Blanco Group are believed to be early Pliocene in age, and the Guaiguaza clay late Pliocene.
