The data comes from the study of Holocene beaches from the Iranian Makran. More exactly, the beaches in Pozm bay, Chabahar bay and the longitudinal beach west of the village of Beris. The data contain field pictures and their legends, results and analytical details of radiocarbon dating, SEM secondary electron images of the analysed shells and the results and analytical details of optically stimulated luminescence dating (OSL). The data is published in support for the paper mentioned in the title. A to D are field pictures and legends of: A - Pozm bay field pictures B - Chabahar bay field pictures C - Beris beach field pictures D - Observed current depositional settings E - Radiocarbon dating results and analytical supplementary information F - Secondary electrons SEM images of the analysed shells G - OSL dating results and analytical supplementary information Radiocarbon analytical details are provided, together with XRD analysis of the Aragonitic shells, SEM secondary electron images of analysed shells and calibration details. Method details are in the paper. OSL results are provided with the analytical details, such as: Environmental dose parameters, OSL raw measurements (out of the machine), OSL Histograms and Dose-Recovery tests. Method details are in the paper.
