Advective diagenesis predicts that large-scale mineral migration will occur when saturated pore fluids move across isotherms (or isobars). A general picture of the change in a given porosity field can be calculated if the fluid flow and temperature (or pressure) fields are known. For more detailed analysis it is necessary to know the details of the chemical equilibria involved, their temperature and pressure dependence, the host rock mineralogy and, in particular, the thermal mass transfer coefficients for the phases involved. In this paper thermal mass transfer coefficients for quartz and calcite have been calculated in detail over the temperature...
