La Cascada Formation a sedimentary formation near Futaleufú in the western Patagonian Andes of southern Chile. Lithologies vary from sandstone, siltstone and conglomerate. The sediment that now forms the rock deposited during the Oligocene and Early Miocene epoch in shallow marine environment. The formation contain fossils of bivalves and gastropods.[1]
The formation unconformably overlies sedimentary rock of Jurassic age, Cretaceous sedimentary rocks of Divisadero Group and Cretaceous granite plutons.[1][2]
