Representative examples for visualisation of the characteristics and distributions of the equivalent doses in abanico plots. A and C: De-s were measured by SAR-OSL protocol on medium (5 mm) aliquots of quartz, B and D: De-s were determined with post-IR IRSL290 protocol on small (2 mm) aliquots of K-feldspar.
