Short summary
In this work, we present a new dataset of strontium isotopes from leaves collected in Santa Catarina and Rio Grande do Sul (Brazil). We combine these data with published South American records to produce a machine learning–based map of strontium isotope distribution across the continent. The dataset and model support studies of ancient mobility, provenance, and environmental and ecological processes.
