Data for: A bioavailable strontium isoscape of Angola with implications for the archaeology of the transatlantic slave trade

This dataset contains supplementary files related to the publication titled "A bioavailable strontium isoscape of Angola with implications for the archaeology of the transatlantic slave trade" by Wang et al. (2023) in the Journal of Archaeological Science (https://doi.org/10.1016/j.jas.2023.105775). In "Predictors", we provide the raster files of climatic and geological data as prepared for the random forest analysis and supplementary table 2 citing the sources of each raster file. In "Results", we provide the R file containing the model results as well as the two raster files which contain a) the predicted strontium isoscape of Angola and b) the predicted standard error for this isoscape. The R script used to model the Strontium isoscape can be found here: https://github.com/gabocks/Angola_SrIsoscape
