| 摘 要： | 以腾冲地区1:20万区域重力调查资料为基础,结合航空磁测、人工地震、地热等资料,综合分析了腾冲地区的火山机构、喷发机制。推测在曲石-蒲川的重力高下面存在壳内浅成高位基性岩浆房。整个火山机构包括曲石-蒲川下伏的基性岩浆房和通过两侧龙川江断裂与腾冲-盈江断裂,以及通过断裂喷出地表的火山岩。

| Abstract: | Based on 1:200000 regional gravity survey data obtained in Tengchong area, in combination with aeromagnetic survey, artificial earthquake and geothermal data, the authors comprehensively analyzed the volcanic edifice and its eruption mechanism in Tengchong area. It is inferred that there is a shallowly formed high-attitude basic magma chamber in the crust below the gravity height of Qushi-Puchuan. The whole volcanic edifice includes the underlying basic magma chamber in Qushi-Puchuan area, the Longchuan River fault and Tengchong-Yingjiang fault through both sides, and volcanic rock ejected from the surface through the fault. |
