Integrated source apportionment and geochemical background assessment of organic and inorganic components in Amazonian upland lakes: insights from an extensive basin-wide geochemical database

Abstract Purpose This study established reliable natural geochemical backgrounds for Amazonian upland lakes and evaluated how lateritic catchment materials are transferred and transformed in lake sediments across Carajás, Araguaia, and Xingu. Methods Ferruginous duricrusts and la...
