. Collected reprints / Atlantic Oceanographic and Meteorological Laboratories [and] Pacific Oceanographic Laboratories. Oceanography there is a strong reflector that parallels the slope, but at the shelf break it dips to the south under the flat shelf. It is covered conform- ably with layered sediments to about 150 m below the shelf. At this depth there is an unconformity, followed by a sequence of horizontally bedded sediments. Profile 3 (fig. 8) is across the sill that separates the eastern and western deeps of the Cariaco Basin. On the northern half of the profile approximately 350 m well-stratified sediments were penetrated, with major disconformities at 70 m and 150 m. Below 350 m there is a possible unconformity, beneath which steeper, southward dipping reflec- tors are seen. The upper 150 m of the sediments south of the shelf break show foreset bedding; below 150 m, there are several faults with small vertical displacements. At 10°A7'N there is a major fault along which the sediments of the slope are downfaulted by 150 m. Minor fold- ing or slumping is associated with this fault. At 10°37'N the well stratified sediments of the northern slope abut against broad folded rocks that are characterized by mostly inco- herent internal reflectors (fig. 11). South of the folded rocks, the ,ec North. Figure 10. Copy of original seismic section of buried terraces southwest of Margarita (Profile 5).
