Abstract

In this paper the authors consider the transport of a single component by pure diffusion and combined diffusion and infiltration under the condition of local equilibrium. Local equilibrium is specified by an isotherm relating the concentration of the component in the solid to that in the fluid at fixed temperature and pressure. The equations are derived for transport in one dimension and these are used to compute concentration profiles in a porous rock adjoining a well-mixed fluid reservoir. The rate laws are used and transport parameters are estimated to set limits on the mechanisms of large-scale metasomatic processes such as granitization and the reconstitution of a residual upper mantle that has been depleted in certain elements by withdrawal of melt.
