Resumen:
Alluvial fans and associated rivers in cretaceous volcaniclastic deposits of Las Plumas Member, Somuncurá-Cañadón Asfalto Basin, Argentina. The volcaniclastic deposits of Las Plumas Member (Cretaceous, Somuncurá-Cañadón Asfalto Basin) were studied to document the relationship between alluvial fans and related streams in amarginal basin setting. Four facies associations were defined in the study region: proximal alluvial fan (AF1), medialalluvial fan (AF2), fluvial channel belts (AF3) and floodplain deposits (AF4). The succession was divided intothree informal sections which show the palaeo-environmental
