- •
It appears that three regional increases in the KAR document three successive humid episodes during the Valanginian.
- •
This is confirmed by contemporaneous increases in DAR and partly also PAR, which highlight higher terrigenous and nutrient fluxes to the Vocontian Basin during these episodes.
- •
The occurrence of the three humid episodes is interpreted to relate to an orbital-paced monsoonal circulation pattern through seasonally reversing movements of air mass heat and precipitation over the northwestern Tethyan margin.
