(Appendix 1) Carbonate content in relation to sediment type described for sediment core CRP-3

In the case of drilling profiles, they help to discern vertical gradation of facies sequences with repeating patterns or with changes in time. A total of 98 bulk samples originating from the Palaeogene strata (Early Oligocene and ?Late Eocene) in the CRP-3 borehole were studied, the depth interval being 0-823.11 metres below sea floor (mbsf).

Ages for the Cenozoic strata (Fig. 1) are taken from the Cape Roberts Science Team (2000a, 2000b), Bücker et al. (this volume), and Sagnotti et al. (2000, this vol.) and are shown in the columns A and B of figure 1. No investigations were performed on the underlying ?Devonian strata from 823.11-939.42 mbsf (final depth). Twenty-eight of a total of 34 lithostratigraphic Cenozoic units of the borehole were sampled (Appendix 1).
