Experimental investigation of the forward reaction I dolomite + 2 quartz = I diopside + 2 C02was carried out in a conventional hydrothermal apparatus, in order to determine the mechanism and the kinetics at a total pressure of 500 MPa and 680'C. The CO2 contents of the fluid phase, consisting of carbon dioxide and water, was found to vary from 80 to nearly 100 mol9o. The experiments lasted up to 365 days (8,760 hours). SEM examination of the reaction mixtures clearly shows a dissolution… CONTINUE READING
