| A Preliminary Study of ESR Dating for Aluminum Center in Quartz from Sediments |
| It is urgent to study and establish a method for evaluating the ages of sediments older than 200 000 years. ESR dating has great potential in this field. This paper gives the paleo-doses for the four layers of loess in Luochuan, Shaanxi Province. The preli-minary results were obtained by measuring Al centers in quartz under 115 K with the ESR method. The paleo-dose increases with the depth of loess without saturation , and this indicates that ESR dating with Al centers might be used to evaluate the ages of sediments older than 200 000 years. |
