Abstract:
Determinations of total carbonate content yield additional information, in the context of integrated investigations, thus enabling or enhancing the interpretation and characterisation of the depositional environment, the processes of sedimentation and the diagenesis of sediments. In the case of drillcores, they help us to discern vertical gradations of facies sequences that have repeating patterns or show changes through time.
This report presents initial results of carbonate investigations on a total of 32 bulk samples from the Quaternary and Miocene strata of the CRP-1 borehole, which reached a final depth of 147.69 metres below sea floor (mbsf). Fifteen out of a total of 18 lithostratigraphic units in the core were sampled (Tab. 1). Fourteen samples (24.85-43.85 mbsf) belong to the Quaternary, whereas 18 samples (44.53-146.51 mbsf) originate from the Miocene strata. The sampling intervals varied from 1-5 m for the Quaternary, and 1-15 m for the Miocene. All the samples originated from sections of core representing not more than 1 cm thickness.
