Abstract | This study aimed to increase the understanding of the history of late Quaternary coastal evolution. An analysis wascarried out on the optically stimulated luminescence (OSL) dates of 12 quartz-rich samples collected from the Chanthaburi paleosand spit and 37 samples from beach ridges at Sam Roi Yot National Park in the upper Gulf of Thailand. The single-aliquotregenerative technique was employed after OSL sample treatment. As a result, both equivalent dose and annual dose providedOSL signals that were internally consistent. The derived OSL ages were in good agreement with the stratigraphic evolution of thespit and beach-ridge progradation. OSL dating of the paleo-sand spit revealed that the age ranged from 17,210 to 1,370 years.The average lateral migration rate of the sand spit varied from 0.2 to 1.8 m/year. The OSL age of the beach ridge plain from SamRoi Yot National Park started from 10,200 to 880 years. The beach ridge plain had an average eastward progradation of 0.4-22m/year. |
