Geochemical characterization of the largest upland lake of the Brazilian Amazonia: Impact of provenance and processes

Abstract: Lake Três Irmãs (LTI), the largest upland lake in the Brazilian Amazonia, located in Serra dos Caraj as, was characterized using multi-elemental and isotope geochemistry (d 13 C and d 15 N) to understand the significance of organic and inorganic sources, weathering and sedimentary processes on the distribution of elements in lake bottom (surficial) sediments. Carbon and nitrogen isotopes from sedimentary organic matter suggest C3 terrestrial plants (forests > canga vegetation), macrophytes and freshwater DOC a… Show more

“…This dataset was used for interpretation of the morphological features and real-time navigation during field surveys, which were supported by a Differential Global Positioning System. The main lithotypes and soil samples were described and collected according to Maurity and Kotschoubey (1995) and Sahoo et al (2017a).…”
