In this study, we use inorganic (metal) and organic (bulk and molecular)markers in sediment samples of the south-eastern Brazilian margin toinvestigate the response of geochemical fingerprints to the complexhydrodynamic processes present in the area. Results indicate the potential ofexport of terrigenous siliciclastic and organic constituents to the upperslope, even in an area with limited fluvial supply.</p><p class="p">Metal contents and especially the ln(Ti ∕ Al) and ln(Fe ∕ K) ratiosmake it possible to recognise the extension of shelf sediments toward theupper slope. Potassium, here expressed as ln(K ∕ Sc) and ln(K ∕ Al)ratios used as proxies of illite–kaolinite variations, proved to be animportant parameter, especially because it allowed us to decipher the imprintof the northward flow of the Intermediate Western Boundary Current (IWBC) incomparison to the southward flows of the Brazil Current (BC) and Deep WesternBoundary Current (DWBC).  Using organic matter analyses, we were able to evaluate the extent ofterrestrial contributions to the outer shelf and slope, even without thepresence of significant fluvial input. In addition, molecular markerssignify a slight increase in the input of C<sub>4</sub>-derived plants to theslope sediments, transported from distant areas by the main alongshoreboundary currents, indicating that the terrestrial fraction of the organicmatter deposited on the slope has a distinct origin when compared to shelfsediments
