| 摘 要： | 腾冲地区存在两类地热流体活动。其中热海- 热水塘地区、马鞍山火山口附近的地热流体活动属火山区地热流体活动,其热源或气体挥发组分的物质来源与近代火山喷发活动或现代幔源岩浆侵入活动直接有关。区内其它地热流体活动多属构造活动成因。在腾冲地区,地热流体逸出He 的3 He/4 He≥1-2 Ra 可作为区别这两类地热流体的可靠指标 |

| Abstract: | In the Tengchong region, there exist two kinds of active geothermal fluids. Only those active geothermal fluids distributed at the Rehai Reshuitang and nearby areas of the Maan shan crater really deserve to be called the volcanic geothermal fluids. It means that their thermal source or the volatile components escaped from the geothermal fluid could be related to the modern volcanic activity or magmatic intrusion. Other geothermal fluids are all generally the thermal discharge caused by the tectonic activi |
