Figure F26. (A) Carbonate and (B) organic carbon stratigraphy and (C) carbonate index for Site 532. Carbonate values are taken as the ratio of carbonate to noncarbonate and are log transformed to avoid the artificial ceiling near 100%. 16 = Stage 16, P/P = Pliocene/Pleistocene boundary, G/M = Gauss/Matuyama reversal, M/P = Miocene/Pliocene boundary. Organic carbon values are transformed to log values to emphasize factors over increments. Data are from Gardner et al. (1984) (age model adjusted).
