| 摘 要： | 对长白山天池火山喷发形成的灰白色空降浮石层、黑色熔结凝灰角砾层和火山碎屑堆积物中 16个炭化木作了系统的14C年龄测定,结果表明天池火山喷发年代为 (1215±15)AD。从火山碎屑堆积中采集的炭化木测定的14C年代要比火山喷发年代偏老,最大可偏离 800a;炭化木树皮的测定结果比较接近火山喷发年代;黑石河、浮石林、锦江大峡谷等地的黑色熔结凝灰角砾层的14C年代结果表明它们也属于(1215±15)AD大喷发的产物

| Abstract: | The largest eruption of the Tianchi Volcano in historical period had not been recorded in historical document. Therefore, the determination of the accurate date of this largest eruption event is of great importance to the estimation of the eruption interval, the evaluation of the eruption risk and the hazard prediction of the future eruption. Basing on the systematical 14C dating of a well-preserved large carbonized wood, Liu Ruo-xin et al (1997) concluded that the largest historical eruption of the Tianc |
