Abstract
Optically stimulated luminescence (OSL) signal resetting of quartz grains from modern fluvial sediments (flood and river-bed sediments ; four samples in total) were investigated to discuss the applicability of OSL dating for fluvial terrace sediments in Japan. Single aliquot regenerative dose (SAR) protocol was employed to estimate the residual doses of samples. Residual doses from the samples range from 1.2±0.3 to 5.9±3.5Gy, and the doses can be converted to the OSL age of 6-0.6ka. Estimating crustal move-ment in the late Quaternary, we concluded that OSL dating has the potential to remark the marine isotope stage (MIS) of fluvial terraces at around 100ka.
