Paleoenvironment evolution of the remoredo formation (Lower jurassic) in the malargüe depocenter, southern mendoza-neuquén basin
Deposits from the Remoredo Formation (Lower Jurassic) are studied in two stratigraphic sections located in the Malargüe anticline (Arroyo Loncoche and Cuesta del Chihuido), where detailed sedimentological and stratigraphic studies were conducted, based on facies, architecture and provenance analysis...
