Figure 3. Correlation between sedimentary sequences sampled at Sites 976, 977, 978, and 979 and in commercial wells on the Iberian shelf. Shown are ages, seismic units, major regional reflectors, and drilled metamorphic basement. Correlation is based on MCS analysis, logging, and stratigraphic data. Seismic units and R-reflectors according to Comas et al. (1992). R-reflectors correspond to major unconformities within sediments. M = Messinian unconformity. Ages of Pliocene-Pleistocene sequences from Comas, Zahn, Klaus, et al. (1996). Inset map shows location of commercial boreholes, connecting lines between holes refer to relative position and distances in kilometers shown at the heading of this figure.
