| Abstract: | To find out major factors controlling the dissolution of calcite in hydrothermal systems, equations describing the relationship between Ca2 concentration at equilibrium and partial pressure p (CO2) are deduced for different thermodynamic conditions. The calculation results show that the intensity of calcite dissolution increases with the increase of p(CO2), temperatures around 363 K are the most favorable ambient temperature for hydrothermal karst development, and that the volume ratio of CO2 gas over water and the mass fraction of foreign ions also have some efrects on calcite dissolution. |
