Multi‐proxy analyses on sediment cores from two closed basin lakes in the Serra Sul de Carajás were used to reconstruct environmental changes in south‐eastern Amazonia during the late Quaternary. The sediment record between 65 000 and 40 000 cal a BP (older dates with high level of uncertainty) is dominated by organic sediments intercalated with detritus (e.g. Al and Ti), indicating fluctuating lake...
This study addresses paleoclimate influences in a southern Amazonia ecotone based on multiproxy records from lakes of the Carajás region during the last 45k cal a bp. Wet and cool environmental conditions marked the initial deposition in shallow depressions with detrital sediments and high weathering rates until 40k cal a
bp. Concomitantly, forest and C3 canga plants, along with cool‐adapted taxa,...
