“…The principal deep-sea geologic data have been collected by the Deep Sea Drilling Project, which drilled several sites during Leg 11 and Leg 43 to document the sedimentary record of the lower rise. Important discussions of relevant deep-sea data are included by Jansa et al (1979), Tucholke and Mountain (1979, in press), Tucholke and Laine (1982), , Mountain and Tucholke (1985), Ewing and Rabinowitz (1984), Emery and Uchupi (1984), Poag (1985b), and Schlee and Hinz (in press).…”

The results from Leg 95 of the Deep Sea Drilling Project bring to completion a series of geological and geophysical studies along a 700-km transect of the New Jersey continental margin. Integration of outcrop, borehole, and seismic reflection data along this transect has revealed the regional stratigraphic framework and has allowed a comprehensive interpretation of the depositional history of the Baltimore Canyon Trough and the adjacent North American Basin. The depositional sequences documented at the boreholes are extrapolated along the grid of seismic profiles to produce isopach maps.Analyses of these data show that sediment dispersal on the New Jersey margin has been governed in large part by sea-level changes, but modified by temporal changes in shelf-edge physiography, sediment sources, and deposition rates. Notable examples include the buildup of a shelf-edge reefal system during the Late Jurassic; its subsequent burial in the Late Cretaceous, as massive turbidity currents and debris flows reached the lower rise; the appearance of a dual shelf-edge system and widespread carbonate production during the Paleogene; rapid progradation of thick deltaic prisms during the middle Miocene; and deep incision of the shelf edge by submarine canyons during the Pleistocene.Massive downslope gravity flows have dominated both the depositional and erosional history of the New Jersey margin during most of the last 135 m.y. The importance of periodic widespread erosion is recorded by correlative unconformities at the boreholes. These unconformities also correlate well with supercycle boundaries of the Vail depositional model, thereby providing field validation of the supercycle framework of the model.

“…Advantage has been taken of minor new information. Cores 391C-6 and -7 are now dated as late Albian through early Cenomanian rather than Albian (Jansa et al, 1979), and the zonation of P. Roth for Leg 76 (this volume) is used to update slightly the Leg 44 results by the same author. Table 2 shows the numerical age of the top and bottom of the zones used to plot the multiple age-depth relationship depicted in Figure 9.…”

“…The last appearance datum of Phoberocysta neocomica (Gocht) in Core 534A-49 correlates the top of the Blake-Bahama Formation with its top in Core 391C-14 from Hole 391C, located 22 km to the southwest. The Blake-Bahama Formation has its type locality at Hole 391C (Jansa, et al, 1979). In Hole 534A, it is 383 m thick and consists of predominantly calcareous lithologies ranging from the stratigraphic level of Core 534A-49 to within Core 534A-92.…”
