[STT53-08] The comparison of Red Themoluminescence dating and Radiocarbon dating
Keywords:AT ash, radiocarbon dating, Red thermoluminescence dating, widespread tephra
A trapped radiation charge dating technique will potentially solve these problems. We focused on development of the Red Thermoluminescence (RTL) dating for tephra since we observed that it captures stable and high intensity RTL signal. We established the dating protocol to deal with tephra to conduct RTL dating. Comparing with ages of tehphras dated by radiocarbon and K-Ar agreed very well with RTL dates showing reliability of our newly developped experimental protocol. Uncertainties of the RTL ages were much reduced and they were comparable to the radiometric dating results.
