Schmidt hammer R-values of coastal alluvial fan surface generations at the south-central coast of the Atacama Desert

This dataset contains Schmidt hammer R-values from, in total, 23 morphostratigraphic units of 12 multi-stage coastal alluvial fans distributed along the south-central coast of the Atacama Desert. Schmidt hammer readings were obtained from exposed boulders of plutonic composition. Individual R-values are provided and stored in a .csv table.
