Figure F6. Bulk sediment delta13C values from Site 1039 correlated to middle Miocene delta13C records from a pelagic section at Site 574 in the equatorial Pacific (Woodruff and Savin, 1991) and from outcrop data on the Maltese Islands (John et al., 2003). Maximum peaks were matched to carbon isotope maximums (CM) 1–6 (Woodruff and Savin, 1991). Note that absolute values between the three sites are not compared because of lithologic differences, but relative trends and amplitudes of positive delta13C excursions are used instead to allow for a robust correlation. Intervals marked with gray bars show specific lithologic intervals that contrast with the general stratigraphic column. In order to use a common scale, delta13C values from the phosphatic layer (Phl) in the Maltese section are shifted 0.8 per mil toward more positive values. VPDB = Vienna Peedee belemnite.
