摘要
通过对滇东主要断裂带上典型温泉的地质背景、环境条件、水化学及碳、氦稳定同位素分析,探讨这些温泉CO2释放的一般规律。分析表明滇东主要断裂带温泉具有特殊的碳来源,其CO2释放与沿小江断裂混杂第三纪煤层(褐煤)有关。
This paper discussed the rules of CO_2 degassing from hot springs on main faults within the east of Yunnan in terms of the analysis of geological background, environmental condition, chemistry of water and carbon, and helium isotope data. The analysis of carbon isotope characteristics explained proper carbon sources of hot springs on main faults within the east of Yunnan. And the reasons of CO_2 degassing are concerned with intermixing Tertiary coal layers along the Xiaojiang fault.
