Short summary
In this work we used a concept called geochemical fingerprinting, with isotopes of neodymium and lead as tools to recognize the main sources and the physical processes responsible for the transport and deposition of sediments on a large area of the South Atlantic margin. Distinct sources, such as Antarctica, the Andean Cordillera, the Río de la Plata basin, and old rocks from the Brazilian shield, are identified.
