长白山天池周围地热活动中CO_2的来源探讨

A Discussion on the Genesis of CO_2 Outgassed in Geothermal Processes Around the Tianchi Lake,Changbai Mountains

碳循环是目前国内外环境地学界研究的重大课题。笔者认为,在长白山地区,以天池为中心,存在着强烈的地热活动,受断裂控制的温泉为地热活动的主要形式。温泉具有深循环特征,温泉气体和泉水中碳质含量高,碳质主要来自上地幔,并与上地幔的挤压流动有关。

Carbon circulation is a very important subject in recent studies of the environmental geology. It is pointed out in this paper that there existed strong geothermal activity with a lot of hot springs controlled by deep faults around the Tianchi Lake, Changbai Mountains, and the plentiful CO_2 outgassed from the hot-springs meanly came from the upper mantle. Also the CO_2 had a connection with the thrust and flow in the upper mantle.
