Abstract:
Determinations of total carbonate contents in the CRP-3 core yield additional information and knowledge, in the context of integrated investigations, thus enabling or enhancing the interpretation and characterization of depositional environment, sedimentation, and diagenesis. 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). Fourty-seven samples (8.97-349.78 mbsf) are from the Early Oligocene section, whereas 51 samples (357.80-788.94 mbsf) originate from the Early Oligocene or ?Late Eocene strata. The sampling intervals are on average about 5-9 m for the Early Oligocene section and about 6-11 in in the Early Oligocene/?Late Eocene strata. All the samples were taken from sections of the profile of not more than 1-2 cm thickness. The samples were split; the portions of the samples were used for investigations with regard to clay minerals (Ehrmann, this volume), heavy minerals (Ehrmann, this volume), and mineralogy as revealed by XRD analyses (Neumann & Ehrmann, this volume).
