摘要
Inorganic CO<sub>2</sub> includes mantle-derived origin and metamorphic origin of marinecarbonate-bearing sedimentary rocks. Through-deep fault is the discharge path formantle-derived and magmatic gases, structural heat of compresso-shear fault provides en-ergy for carbonate rocks to produce CO<sub>2</sub>; meanwhile, local high pore pressure causedby CO<sub>2</sub> concentration reduces the internal friction resistance of rocks and stimulatesor enhances tectonic action. CO<sub>2</sub> discharge belts coinciding with global
