| 摘 要： | 在前人对腾冲火山活动分期基础上，通过实地考察。依据地层披盖关系，地丑对比、火山财貌、岩石类群、岩性等特点并参考同位素年龄测定值，把腾冲新生代火山活动分为四个活动期、九个亚期。第一期火山活动活动始于上新世，第二期火山活动为早更新世，第三期火山活动为晚更新世。第上期火山活动为全新世。

| Abstract: | On the bases of forefathers about period division of volcano activity in Tengchong, according to stratum covering relation, stratum comparison, vocano geomorphology, rock type and property, considering isotopic dating, activities of Tengchong volcano in the Cenozoic Era have been divided into 4 periods and 9 sub periods through site survey. The first period started from the Pliocene Epoch, the second from the early Pleistocene Epoch, the third from the late Pleistocene Epoch, and forth from the Recent Epoch. |
