Inorganic and organic geochemical fingerprinting of sediment sources and ocean circulation on a complex continental margin (Sao Paulo Bight, Brazil)

摘要

In this study, we use inorganic (metal) and organic (bulk and molecular) markers in sediment samples of the south-eastern Brazilian margin to investigate the response of geochemical fingerprints to the complex hydrodynamic processes present in the area. Results indicate the potential of export of terrigenous siliciclastic and organic constituents to the upper slope, even in an area with limited fluvial supply.
