[MTT48-P06] Sequential radiocarbon measurement on peaty sediments to reconstruct high precision age model of mash deposits
Keywords:Radiocarbon dating, Wiggle matching, Tephra
Blaauw et al. (2003, QSR) compares the calendar year calibration curve with the continuously sampled radiocarbon dating values, assuming that the peat layer deposition rate does not change for a certain period, Can be estimated.
Although this approach has been tried (eg Ishizawa et al., 2017, QG) to apply tsunami sediments contained in peat deposits to high precision age dating, verification of accuracy using known age class I have not been touched.
Therefore, in this study, we aimed to verify the age determination accuracy by seeing the age by the peat-wiggle matching method for the tephra containing layer whose eruption age is clear by the history record.
