OSL signal resetting of modern fluvial sediments; A Verification of sediments along the Nishiki River

Tokuyasu, Kayoko; Tanaka, Kazuhiro*

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 the samples. Residual doses from all samples range from 1.20.3 to 5.93.5 Gy, and the doses can be converted to the OSL age of 6-0.6 ka. We concluded that the OSL dating has the potential to remark the marine isotope stage (MIS) of fluvial terraces at around 100 ka.
