Geogenic controls and anthropogenic inputs on the seasonal hydrogeochemical variability of the Paraopeba River basin, Brazil

Abstract This study investigates the combined effects of geology, land use and land cover, hydrological seasonality, and disturbance history on the hydrogeochemistry of surface waters in the Paraopeba River Basin (PRB), located in Minas Gerais State, southeastern Brazil, and form...

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...
