Petrology, sedimentary cycles and depositional environment of the Yacoraite Formation (Upper Cretaceous) of Corralito River, Salta

The sedimentological and petrographical characteristics of siliciclastic and carbonate facies within the Yacoraite Formation at Corralito river are described. The rocks contain ostracods, molluscs and algae, as well as coated grains and polygenetic intraclasts. Mixed terrigenous elements are importa...
