Figure F28. Simplified time-stratigraphic chart comparing the lithostratigraphic successions encountered on the Newfoundland and Iberia conjugate margins. The Iberia margin data are from previous DSDP and ODP volumes, with corresponding lithologic units shown on the left sides of the columns. For comparison, a similar summary of formally defined sedimentary formations is provided (at right) for the geographically separate North American Basin in the western central North Atlantic. Thicknesses of the units are shown on the right sides of the columns. TD = total depth.
