Stable isotopes of detrital carbonate from sediment core MD01-2444 on the Portuguese Margin, Marine Isotope Stage 3

Stable isotopes of detrital carbonate were measured on single grains taken from the peaks of HL4 (10.06 m) and HL5 (11.98 m) in MD01-2444. Detrital carbonate grains were picked from the >150 μm fraction and leached in a weak acid. Each detrital carbonate grain was ground and between 20 and 60 μg of powdered sample was loaded into Exetainer vials and sealed with silicone rubber septa using a screw cap. The samples were flushed with CP grade helium, then acidified with 104% orthophosphoric acid, left to react for 1 hour at 70 degrees Celsius and then analysed using a Thermo Gasbench preparation system attached to a Thermo Delta V mass spectrometer in continuous flow mode. Each run of samples was accompanied by 10 reference carbonates (Carrara Z) and 2 control samples (Fletton Clay). Carrara Z has been calibrated to VPDB using the international standard NBS19. The results are reported with reference to the international standard VPDB and the precision is better than ±0.08 per mil for d13C and ± 0.10 per mil for d18O. The record was generated by D.A. Hodell.
