The general sedimentary architecture is represented by underlying sandy bar (SD) deposits covered by muddy bar top and floodplain (BT/F) deposits. Pictures were taken during the dry season (September to November). Sedimentary facies are shown in Fig. 6. a Right margin of the Solimões River, upstream the Tefé River mouth near sampling site ALC29. b Left margin of the Solimões River, near the Purus River mouth. c Right margin of the Solimões River, upstream the Negro River mouth near sampling site NSM20. d Right margin of Amazon River upstream of the Tapajós River mouth, near sampling site TAP27. e Island of the Xingu River, near the city of Altamira. Scale is approximate. Geographic coordinates of sampling sites are presented in Supplementary Data 1.
