“…Seismic resolution did not allow further differentiation within these deposits. Greenlee & Moore (1988) and Greenlee et al (1988, 1992) used commercial well information and proprietary industry seismic data to date lower Miocene seismic sequences. These authors used sequence stratigraphic criteria outlined in Payton (1977) to define four Oligocene, four lower Miocene and four middle Miocene sequences.…”

“…These authors used sequence stratigraphic criteria outlined in Payton (1977) to define four Oligocene, four lower Miocene and four middle Miocene sequences. Greenlee & Moore (1988) and Greenlee et al (1988, 1992) concluded that lower Miocene sequences are thin units that depict limited progradation past Oligocene clinoforms. However, rapid margin progradation dominates the middle Miocene owing to significantly increased siliciclastic sediment supply.…”

“…These seismic data comprised widely spaced profiles using low‐frequency sources designed to image rift‐stage sediments 10+km below the seabed, and were not ideal for resolving details within the much shallower Cenozoic section. Later studies, some of which incorporated commercial seismic data, outlined suspected Palaeogene and Neogene sequences (Poag & Schlee, 1984; Poag, 1985a, b; Poag & Ward, 1987; Greenlee & Moore, 1988; Greenlee et al , 1988, 1992). Based in part on these analyses, but more significantly on research‐based higher‐resolution MCS profiles, several drilling expeditions attempted to establish correlations between sequence evolution, facies succession and sea‐level change (Deep Sea Drilling Project (DSDP) Leg 95, Poag et al , 1987; Ocean Drilling Programme (ODP) Legs 150, Mountain et al , 1994; Ocean Drilling Programme (ODP) Legs 174A, Austin et al , 1998).…”

Early Miocene sequence development across the New Jersey margin

Sequence stratigraphy provides an understanding of the interplay between eustasy, sediment supply and accommodation in the sedimentary construction of passive margins. We used this approach to follow the early to middle Miocene growth of the New Jersey margin and analyse the connection between relative changes of sea level and variable sediment supply. Eleven candidate sequence boundaries were traced in high‐resolution multi‐channel seismic profiles across the inner margin and matched to geophysical log signatures and lithologic changes in ODP Leg 150X onshore coreholes. Chronologies at these drill sites were then used to assign ages to the intervening seismic sequences. We conclude that the regional and global correlation of early Miocene sequences suggests a dominant role of global sea‐level change but margin progradation was controlled by localized sediment contribution and that local conditions played a large role in sequence formation and preservation. Lowstand deposits were regionally restricted and their locations point to both single and multiple sediment sources. The distribution of highstand deposits, by contrast, documents redistribution by along shelf currents. We find no evidence that sea level fell below the elevation of the clinoform rollover, and the existence of extensive lowstand deposits seaward of this inflection point indicates efficient cross‐shelf sediment transport mechanisms despite the apparent lack of well‐developed fluvial drainage.

“…The New Jersey Shelf is a passive margin (Steckler et al, 1999) subjected to slow thermal subsidence (6.5 m/ma; Greenlee et al, 1988). This reconstructed tectonic movement is slow enough to assume that it has not had a significant influence over the relatively short period (40 ka) that is the subject of this modeling study.…”

The sequence boundaries identified were related to those of Greenlee et al (1988), who correlated them to the Haq et al (1987) inferred global sea-level record.

The styles of soft-sediment deformation, mineralogy, and biostratigraphy of mass-transport deposits recovered from Leg 150 drill sites (902-906) provide important new information on the erosional and sedimentary history of the New Jersey continental slope and rise, and on the relationship of mass-wasting processes to changes in relative sea level. Nine distinct sedimentary facies are recognized within these mass-transport deposits, which mainly represent muddy slumps and debris flows, and to a lesser extent, sandy mass flows. These sedimentary facies, coupled with the ages of their clast and matrix material, reveal source areas, transport mechanisms, and depositional processes, and the relative contribution of downslope transport to the evolution of the continental rise.Mass-wasting deposits compose 10%-15% of the total sediment recovered beneath the continental slope at Sites 902, 903, and 904. Upper Miocene and Pleistocene debris flows and slumps frequently correlate to sequence boundaries beneath the upper paleoslope at Site 903, and to a lesser extent, beneath the middle paleoslope at Sites 902 and 904. In contrast, upper Oligocene to upper Miocene sands and sandy mass flows correlate to sequence boundaries beneath the middle paleoslope at Sites 902 and 904 and not beneath the upper paleoslope at Site 903. Mass flows at these sites document shelf and coastal plain erosion and sediment transport to the basin during glacioeustatic lowering. These observations suggest a correlation between mass-transport deposits and sequence boundaries. However, this correlation is complex because preservation of mass-wasting deposits appears to have been significantly influenced by the morphology and gradient of the existing paleoslope. In addition, mass-transport deposits also occur within sequences especially during the upper Miocene and Pleistocene.Site 906 was drilled in the floor of modern Berkeley submarine canyon. The sedimentary facies recovered from the middle Miocene section document an episode of canyon excavation and infilling. The Berkeley and middle Miocene canyon fill facies are different from the mass-transport deposits that characterize intercanyon regions of the slope (they contain debris flows with clasts of diverse ages and multiple turbidites). The middle Miocene canyon cutting event apparently occurred very rapidly (~l.l m.y.) during a single third-order sea-level cycle (13.5-12.4 Ma) and the mass-transport deposits at the base of the canyon fill rest upon a Type I sequence boundary, which forms the canyon floor.Downslope transport of sediment via mass movements has episodically contributed to the evolution of the upper continental rise. At Site 905 on the continental rise, approximately 30 m of mass-transport deposits were accumulated during the middle Miocene. Benthic foraminifer assemblages indicate that some deposits originated in the upper slope. The lithology of the clasts in these deposits indicates they were derived from canyon excavation on the continental slope and the age of the matrix...
