Saline paleolake of the Cañadón Asfalto Formation (Middle-Upper Jurassic), Cerro Cóndor, Chubut province (Patagonia), Argentina

The carbonate-evaporitic sequence of the Cañadón Asfalto Formation that crops out in Cañadón Carrizal (Chubut province, Argentina) is characterized by a lacustrine facies association. This sequence includes an extensive biohermal belt, flood facies with high lake-level and low lake-level stages, and...

This sequence includes an extensive biohermal belt, flood facies with high lake-level and low lake-level stages, and desiccation - evaporation facies.

description The carbonate-evaporitic sequence of the Cañadón Asfalto Formation that crops out in Cañadón Carrizal (Chubut province, Argentina) is characterized by a lacustrine facies association.
