Figure 6. Age modelling results.

Age modelling results obtained for cores CALA 04 (left) and CALA 05 (right) using the P_Sequence (a Bayesian model of deposition) implemented in the computer program OxCal 4.1; this software assimilates sedimentation as a random process following a Poisson law³⁰; marine data from (ref ⁵²).The regularity of sedimentation is determined by the k parameter (here k = 3 reflects small variations in sedimentation rate as deduced from radiometric dating analysis). The model finally calculates the age of each corrected depth corresponding to a turbidite and generates the 95.4% probability age ranges (2σ). See Supplementary Material 4 and 5 for further details.
