| 摘 要： | 云南腾冲火山区是我国少数几个近代有火山活动的地区之一，它由多座第四纪火山组成。其中马鞍山是规模较大，可能喷发较晚的一处火山。从马鞍山火山锥附近采集了２个火山岩样品，进行了热释光测年分析。热释光年龄表明马鞍山最后一次大规模的火山喷发发生在全新世，可能距今约２５００～３５００年。

| Abstract: | Tengchong volcanic area is one of the few volcanic activity areas in China, which is formed by many volcanoes in Quaternary Among them, Maanshan volcano is the one with bigger scale and possibly latest eruption Two rock samples collected from Maanshan volcanic cone were dated by thermoluminescence (TL) The results show that the latest eruption took place in Holocene, 2500-3500 years from now |
