Facies and architectural variability of sub‐seismic slope‐channel fills in prograding clinoforms, Mid‐Jurassic Neuquén Basin, Argentina

Abstract: Most slope‐channel outcrop studies have been conducted at continental margin‐scale on seismic data. However, in foreland and back‐arc deepwater settings, sub‐seismic scale slope channels hold equally important information on deepwater sediment delivery, often in hydrocarbon‐bearing provinces. One such slope‐channel system is examined in Lower Jurassic prograding shelf‐margin clinoforms in Bey Malec Estancia, La Jardinera area, southern Neuquén Basin, Argentina. In a 4 km wide, 300 m tall, slightly oblique‐ to … Show more

“…The sharp bases of beds and bedsets associated with the characteristic aggradational stacking in this clinothem indicate repeated cutting and filling of channels. The turbidite deposits are interpreted as the infills of channels that are sited, according to the outcrop, on the uppermost parts of the deepwater slope (see also Gan et al ., ).…”

“…Mass-transport processes mainly affect the margin slope. Archive potential increases in modern mud belt of the proximal, outer shelf and deepest sectors the margin as highlighted by frequent downcutting of fluvial and delta-distributary channels (Gan et al, 2019) and by shelf-edge incisions . Thick successions showing vertically stacked progradation-transgression units or an overall tendency to stack units from a progradation to aggradation style (as judged from the shelf-break trajectory).…”
