Supplementary Material — Late Holocene alluvial records reveal geogenic and anthropogenic controls on potentially toxic elements in the Carajás Mineral Province, Brazilian Amazon

Supplementary material for the article "Late Holocene alluvial records reveal geogenic and anthropogenic controls on potentially toxic elements in the Carajás Mineral Province, Brazilian Amazon" (Guimarães et al.), submitted to Anais da Academia Brasileira de Ciências (AABC), manuscript 2026-0264. This repository contains: Appendix S1 (detailed description of the chronostratigraphic units of the study site, with its own reference list); Table SII (geochemical concentrations of major, minor and trace elements in the studied alluvial deposits); and Table SIII (elemental chemical ratios in sediments and overlying catchment rocks).
