Figure F5. Comparison of carbon and oxygen isotope compositions between reference Site 1039 and underthrust section at Site 1040. Transformation from Site 1040 depth to the corresponding depth in reference Site 1039 is based on the sediment horizon correlations that were established by calculating the solid height profiles (i.e., the theoretical depth profile in a decompacted sedimentary section of solid material only, calculated from measured porosity data) at each site and by assuming constant accumulation rates (D. Saffer, pers. comm., 2002). Also shown are data points from Site 1253 which are projected into the depth of Site 1039. Error bars show precision of isotope measurements (±0.1 per mil) and error of depth transformation (3.5 m). Yellow bars indicate four specific intervals where delta18O values vary significantly between the reference and underthrust site. VPDB = Vienna Peedee belemnite.
