| 英文摘要 | Controversy exists regarding the chronology of loess in the Nanjing area in Jiangsu Province and the Jiujiang area in Jiangxi Province, East China. The chronology is of special interest, because the age of the initial accumulation for loess in these areas indicates that dust accumulation has been extended from the Loess Plateau in North China to East China at that time. This implies a threshold in the evolution of the East Asian monsoon, with the strengthened winter monsoon transporting aeolian dust further to the south. In this study nine luminescence samples were collected from the Jiujiang area and four samples from the Nanjing area. Quartz grains of 38-63 mu m were isolated and the single-aliquot regenerative-dose (SAR) protocol was employed for De determination. For all samples from the Nanjing area, during the SAR measurement cycles the test-dose sensitivity was dose dependent and dropped significantly when the regeneration dose reached >300 Gy, while it increased linearly when the regeneration dose value ranged from 25 to 300 Gy. The reason for this is not yet known. The OSL chronology and its implications for paleoenvironmental change are discussed. It is concluded that: (1) loess deposition in the Jiujiang area started in the early Last Glaciation; and (2) the first loess layer in the Nanjing area was deposited during the last Glaciation.
