内容記述 |
Thermoluminescence（TL）dating by the total-bleach method has been used for the age determination of sediments. It is difficult to get the reliable ages by this method, because there is no routine method to check accurately the level of the residual TL. In this study, the amounts of residual TL of quartz fine grain (ca.1-8μm) samples were compared with those of residual OSL of the same samples by bleaching them with a 60-krx light source. As a result, we found that elapsed time of light exposure, which guarantees the residual OSL intensity nearly zero, can be a criterion to estimate the level of the residual TL. TL age of a Chinese loess deposit was estimated by the improved total-bleach method using the estimated residual TL comparing with the residual OSL. The TL age obtained was in good agreement with OSL age of the same loess sample. |
