Résumé
The fluvio-lacustrine sequences in the Nihewan Basin, northern China, provide importantterrestrial archives about Palaeolithic settlements and, therefore, about early human occupation inhigh northern latitude in East Asia. Here we present detailed ESR dating of the Donggutuo Palaeo-lithic site, located in this basin. Four levels A, B, C and E of the Donggutuo archaeological layer yieldESR ages ranging from 1060±129 ka to 1171±132 ka with a mean of 1119±132 ka. The ages are con-sistent with the paleomagnetic data, which show that the Donggutuo Palaeolithic site lies just belowthe onset of the Jaramillo normal subchron (0.99-1.07 Ma). Furthermore, our results indicate that thereliable ESR dating range of bleached quartz using Ti-Li centre can be effectively extended to1100 ka and the Ti-Li centre was zeroed before the last deposition, which requires improvement ofthe understanding of the bleaching mechanism conditions
