摘要
Based on the study of hydrothermal experiment on the interaction between the K-feldspar, plagioclase and CO2 fluids at different temperature (100 ℃, 200 ℃and 300 ℃), it is suggested that the corrosion intensity of feldspar should gradually be enhanced as the temperature increases, and albite is stronger than the corrosion degree of K-feldspar. Spherical ferrous oxide precipitates on the sample surface at 300 ℃ after the reaction between plagioclase and CO2 fluids. The formation of siderite (at 200 ℃) and the precipitation of FeO (at 300 ℃) on the sample surface showed that the CO2 can be captured in the mineral as the form of carbonate, the upper limit temperature that can be captured is around 200 ℃.
