Carbon mineralization, especially geological carbon mineralization, is one of the promising options. It is because it has a large capacity to store CO2 permanently. Peridotite rock has been recognized to have a high potential for CO2 storage since it has a high content of Mg-rich minerals (olivine and pyroxenes) which is far-from-equilibrium. However, it has been barely explored that the rock alteration and carbonation mechanisms in specific naturally occurring systems so far. Therefore, we explored the effect of specific geologic conditions near peridotite massif in this research. The experiments were performed under high pressure and high temperature with various fluid chemistry using the autoclave. The results speculate that the factors such as chemical composition, alkalinity, and pH affect the crystal structure of products and the extent of carbonation.
