The Middle Jurassic Lajas Formation of the Neuquén Basin (Argentina) records marginal marine sediments, mainly as deltaic systems. However, there is still controversy regarding its dominant process. The Lajas Formation has been interpreted as a tide-dominated delta, fluvio-dominated delta with hyperpycnal discharges, fluvio-dominated with tidal modulation delta, and a delta that show mixed energy signatures (fluvial, tidal,and wave action). These contrasting interpretations lead to different paleoenvironmental frameworks based on the interpretation of body forms and architectures, facies associations,and sedimentary structures (both organic and inorganic) characterization. The observation, description,and analysis of outcrop data (Bajada de Los Molles, Arroyo Covunco, Sierra de la Vaca Muerta,and Arroyo Carreri outcrops), allowedthe elaboration of a regional schematic paleoenvironmental model, later integrated with subsurface data (Sierra Barrosa, Aguada Toledo,and Sierra Barrosa Norte core samples and well logs). The observations made in the Sierra Barrosa/Aguada Toledo Field suggest that most of the column corresponds to a fluvial-dominated delta with hyperpycnal discharges, which subordinately develops wave-dominated deltas, with tidal effect being the least influential. This is supported by the fact that no organic or inorganic sedimentary structures typical of tidal processes were recognized.
