Abstract:
Determinations of total carbonate contents on CRP-2/2A cores yield additional information and knowledge, thus enabling or enhancing the interpretation and characterization of the depositional environment, the sedimentation, and the diagesiesis of sediments. In case of drilling profiles, they help to discern vertical gradation of facies sequences with repeating patterns or with changes in time. A total of 74 bulk samples originating from the Quaternary, Miocene and Oligocene strata of the CRP-2 and CRP-2A boreholes, final depth 624.15 metres below sea floor (mbsf). 38 of a total of 41 lithostratigraphic units of the boreholes were sampled (Tab. 1). Two samples (7.11-16,97 mbsf) belong to the Quaternary, 1 sample (23.54 mbsf) belongs to the Pliocene, 12 samples (30.71-123.7 mbsf) to the Miocene, whereas 53 samples (135.24-623.81 mbsf) originate from the Oligocene strata. The sampling intervals vary from 7-9 m for the Quaternary, 5-12 m for the Miocene or 3-12 m for the Oligocene. All the samples originate from sections of the profile of not more than 1-2 cm thickness. The samples were partioned; the partions of the samples were used for investigations with regard to clay minerals (Ehrmann, 2000), heavy minerals (Polozek, 2000), and XRD analyses (Neumann & Ehrmann, 2000).
