Novel insights into the post-IR IRSL200 signal bleachability of single-grain K-feldspars in fluvial modern analogues from the Southern Central Andes, Chile

This dataset provides geochemical compositions measured by electron microprobe analysis, generated to support the study “Novel insights into the post‑IR IRSL200 signal bleachability of single‑grain K‑feldspars in fluvial modern analogues from the Southern Central Andes, Chile.” It documents the mineral chemistry underlying the single‑grain luminescence behaviour investigated in the paper.
