The outgas types and amount of different gas resource varied with the different geological conditions and evolution processes. There are four outgas models including the model in which inorganic gas directly overflows from mantle matter through lithospheric fracture,the model of heat flow piercement outgas,the model of volcano-magma outgas,and the model of carbonate rock outgas due to heat metamorphism.
