Résumé
The COL17c composite record was analyzed based on pollen, charcoal, the elemental composition of bulk sediment obtained by X-Ray fluorescence scanning (XRF) and biomarkers (branched glycerol dialkyl glycerol tetraethers (brGDGTs), n-Alkanes and Hopanes). We aimed to characterize early states of the Atlantic forest to evaluate the link with southern hemisphere climate variability at orbital scales using a sediment core located at the transition between SASM (South american summer monsoon) and subtropical front influence.
