| Abstract: | Chemical kinetics has very important effects on geochemical researches of ore-forming processes. The main applications of chemical kinetics involve seven aspects. This paper chiefly introduces the experimental methods of chemical kinetics in the geochemical study and some experimental results about the chemical reaction kinetics of carbonate, silicate, oxide and sulfide minerals etc. It also presents Helgeson's theory of mass transfer and its applications in studying the transfer of hydrothermal solution in country rocks. Furthermove, the authors studied the dissolution and the alteration of country rocks, the mineralization processes and their mutual relationships in both thermodynamic properties and dynamic behaviours of the geochemical system. |
| Keywords: | mineral reaction kinetics kinetic behaviour reaction progress degree moving-state process pH-state method free-drift method kinetic control diffusion control transfer of hydrothermal solution theory of mass transfer |
