摘要
腾冲不但是现代火山活动区,也是地热异常区,这里温泉、热泉及喷气孔到处可见。本文叙述了热水中气体及其它重要化学成分的组成和分布特征。按其气体成分特点,进行了简要的分带、分区,并且讨论了地热流体及其与地质构造、火山和地震活动的关系。
Tengchong is a famous active area of the modern volcano, where the hydrothermal activity is very violent.In this paper, the geochemical characteristics of the gas in thermal water are expounded. Tne main component of the thermal water ia the middle belt is CO2,whose contents are over 90 percent,and some He and H2 are also included. The main component of the thermal water in the east and the west belts is N2, whose contents vary from 90 to 98 persont. Some components in the gas of the thermal water, such as H2, He, H2S, CO2 and CH4 are related to deep magma and the volcanic activity.
