“…Based on information from exploration wells, the Maastrichtian to Quaternary sediments of the outer shelf are of alternating marine (Maastrichtian‐Paleocene, Miocene, Quaternary) and continental (Eocene‐Oligocene, Pliocene) origin [ Loegering et al ., ]. Toward the slope, the sedimentary sequences change toward a completely deep‐marine facies [ Autin et al ., ; Loegering et al ., ; Marcano et al ., ]. The multichannel seismic profiles used here allow us to investigate sediment deposition in water depth levels from 200 to 5000 m and thereby cover the modern day interfaces of all surface to deep water masses along the continental margin and slope (Figure ).…”

A detailed reflection seismic investigation on sediment deposition at the northern Argentine margin (37°S to 42°S) resolves major modifications in oceanographic circulation during the Cenozoic, which resulted from variations in both climatic and tectonic processes. After an extensive erosional period following the onset of glaciation of Antartica at ~34 Ma, which affected all water depth levels, a buried elongated mounded drift within the continental shelf was shaped by bottom current activity during the Miocene. This may represent the earliest deposits of the Malvinas Current that branches from the Antartic Circumpolar Current and today is part of a complex shallow water circulation system known as the Brazil-Malvinas confluence. At the same time a major terrace grew to its present form on the upper slope indicating that a precursor of Antarctic Intermediate Water was also part of the BrazilMalvinas confluence. After another major erosional phase inferred from a seismic unconformity at ~6 Ma, sheeted drifts, mounded drifts and sediment waves formed at the continental rise during the Pliocene/Pleistocene. These extensive contourite deposits are diagnostic for a steady north setting bottom flow at the depth level of todays Antarctic Bottomwater. Evidence for downslope transport mainly stems from the presence of buried turbidites and canyon related depocenters. These features can be related to Andean uplift during the Eocene and to the activation of the canyon system during the Pliocene.

“…Catastrophic events such as emplacement of MTDs in deepwater environments are capable of overrunning background sedimentation and may likewise, decimate or alter the configuration of fluid flow structures (Marcano et al, 2013). The temporal variability of the pipes in the eastern part of the study area appears to be affected by the emplacement of the MTDs during the Late Pliocene (Frey-Martinez et al, 2005a).…”

“…The 1D modeling study reveals the critical moments for the maturation of source rocks in South Atlantic basins, e.g. Campos basin span from Early to Late Cretaceous (Marcano et al., 2013). The source rocks reached peak oil generation at approximately the Miocene, and most are still in the oil window under the influence of heat insulation by overlying thick salt rock.…”

The basins of the South Atlantic passive margins are filled with early rifting stage lacustrine sediments (Barremian, 129-125 Ma), transitional lacustrine and marine sediments (Aptian, 125-113 Ma), and drift stage marine sediments since early Cretaceous (Albian, 113 Ma). The South Atlantic margins can be divided into three segments by the Rio Grande Fracture Zone and the Ascension Fracture Zone according to variations in the basin evolution history and configuration style. The lacustrine shale and marine shale source rocks are developed in the rift stage and drift (post-rift) stage in the South Atlantic passive margins, respectively. The southern segment of the margins is dominated by the lacustrine sedimentary filling in the rifted stage overlain by a thin marine sag system as a regional seal, where the hydrocarbons are mainly accumulated in the structural-stratigraphic lacustrine reservoirs formed in the rift stage. The middle segment developed salty rift-sag-type basins with rift and sag systems and with salt deposited in the transitional intercontinental rift stage, where the lacustrine shale in the lower part of the rifted lacustrine sequence and the marine shale in the lower part of the sag sequence formed in the marine post-rift stage are high-quality source rocks. This segment in the middle is mainly dominated by pre-salt lacustrine carbonate and post-salt marine turbidite plays. The northern segment is characterized by sag-type basins with a narrowly and locally distributed rifted lacustrine system and its overlying widely distributed thick marine sag systems. Gravity-flow (mostly turbidite) marine sandstones as good reservoirs were extensively developed in the sag stage due to the narrow shelf and steep slope. The post-rift marine shales in the lower part of the sag
