| 摘 要： | 首次利用ＴＬ测年技术，测定了五大连池火山群中两座最新喷发的火山熔岩中的烘烤捕虏体的年代。测定结果（（２６４±１９）ａＢ．Ｐ．，（２７３±１９）ａＢ．Ｐ．）在误差范围内与喷发的历史记载（１７１９～１７２１年）一致，表明这两座火山是同期喷发的产物，同时也表明利用ＴＬ测年技术能比较准确地测定年轻火山活动的年代，它为恢复火山最新喷发历史的研究提供了一种比较可靠的年代测定途径

| Abstract: | The ages of bake layers of xenolith within the volcanic lava associated with the recent eruption in Wudalianchi volcanic cluster have been dated by TL dating technique for the first time. The results ((264±19)a B.P. and (273±19)a B.P.) are consistent with historical record (1719～1721) of the volcanic eruption in the error range. It shows that the lava made of these volcanoes is the eruptive materials with the corresponding period. And it also indicates that the very young ages of volcanic erupt |
