| Abstract: | 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. |
