Relationships among thermoluminescence color image, impurity concentration and characteristics of OSL signal from quartz grains extracted from sediments in Japan

Tokuyasu, Kayoko

Various source rocks are distributed in Japan, where is located at mobile belt. Thus, quartz grains in sediments are derived from a wide variety of source rocks, it is likely that the characteristics of OSL signal in the quartz grains depend on the source rocks. In general, detectable fast component in a quartz grained sample is essential for accurate OSL dating. However, even though the fast component was detected in quartz grains from some fluvial sediments in Japan, the OSL ages were underestimated due to unstable OSL signal at room temperature. To understand this issue and to determine selection condition of applicable sample for OSL dating, I report here on the thermoluminescence color image (TLCI) and impurity concentration of sediment samples which are likely related to the characteristics of OSL signals and the geological settings.
