Description

Caleta Godoy's strata are always found horizontally even in places where the underlying Santo Domingo Formation have its strata tilted 90 degrees (angular unconformity). The formation contains mollusc fossils and ichnofossils of Ophiomorpha and Planolites can be observed. Caleta Godoy Formation was deposited in a shallow marine environment during a small marine transgression different from that associated with Santo Domingo Formation. The formation is analogous to Licancheu and Tubul Formation found further north.[2]
