Evaluation of irreversible reactions in geochemical processes involving minerals and aqueous solutions; I, Thermodynamic relations


, : Evaluation of irreversible reactions in geochemical processes involving minerals and aqueous solutions; I, Thermodynamic relations. Geochimica et Cosmochimica Acta 32(8): 853-877

The application of thermodynamic principles of chemical petrology and solution chemistry to the study of geochemical processes permits the prediction of the consequences of reactions between aqueous solutions of electrolytes and typical mineral assemblages. Thus a given geochemical process can be represented by a set of reversible and irreversible chemical reactions corresponding with an array of linear differential equations relating partial equilibrium and non-equilibrium in thermodynamic systems. The simultaneous evaluation of these equations defines the compositional change and redistribution of species in the aqueous phase, the order of appearance of stable and metastable phases, and the mass transfer resulting from irreversible reactions between the minerals and the aqueous solution. The pertinent thermodynamic relations are summarized.

We investigated whether or not it was possible to reduce the sample size and observation period under new selection criteria for an ost...
