Abstract

A method for estimating Gibbs free energies and stabilities of clay minerals is proposed for use with computer programs aimed at calculating the chemical evolution of natural water-rock systems. This is based on (i) a model for ideal solid solutions of a large number of end-member compositions and (ii) a data set of estimated solubility products from 36 end-members. The application of the method to the production of experimental or natural clay stabilities is discussed.

Résumé

Résumé

Une méthode d'estimation de l'énergie libre de Gibbs et de la stabilité des minéraux argileux est proposée en vue de son utilisation dans les programmes d'ordinateurs déterminant l'évolution chimique des systèmes eau-roches naturels. On présente d'abord un modèle pour des solutions solides idéales d'un grand nombre de constituants puis on propose un ensemble de produits de solubilité estimés pour 36 constituants. Finalement on discute de l'application de la méthode à la prévision des stabilités des argiles dans la nature ou dans les conditions expérimentales.

Diese basiert auf: (a) einem Modell von idealen Mischkristallen aus einer großen Anzahl Endgliedzusammensetzungen und (b) einem Datensatz geschätzter Löslichkeitsprodukte von 36 Endgliedern. Es wird die Brauchbarkeit der Methode zur Vorhersage experimenteller oder natürlicher Tonstabilitäten erörtert.
