To discuss that metamorphic carbonate rocks release the amount and ability of CO2
flux, which metamorphic carbonate rocks release in contact metamorphism, is analyzed and calculated quantitatively on the basis of metamorphic reaction and time integrated fluid flux. The results suggest that the value of CO2
flux is 0.729×104
is provided mainly by contact metamorphic reations. The generation and release of CO2
are positive correlation with the degree of metamorphism, and XCO2
in fluids continuously increases form the zone of dolomite to the zone of calcite, but in the zone of essonite, fluid flux is the largest and XCO2
sharply decreases for the influence of magmatic water.
