Sistemas fluviales efímeros del Jurásico Superior en la cuenca Neuquina, República Argentina

A sedimentary model for the Kimmerídgian Tordillo Formation of the Neuquén basin is proposed. Through the measurement of three strati graphic logs, an ephemeral fluvial system associated with continental mud flats is proposed. The proximal areas are characterised by gravelly and sandy-gravelly longi...
