Entropy Balance and "Entropy Condition" in Infiltration Metasomatism

Françis Conrad 1 Michel Cournil 2, 3 Bernard Guy 2, 3, 4 
Abstract : The chemical transformation of a rock by a pervading fluid in disequilibrium with it, is modelled by a partial differential equation of hyperbolic type : in some cases, this may admit discontinuous solutions. In the mathematical framework suitable for the discontinuous solutions, it is necessary to add to the starting equation a so called entropy condition, wich is made clear here.
