 William M. White

William M. White wrote Geochemistry by William M. White, a quantitative treatment of Earth materials and chemical processes. Its discussion of multicomponent systems connects thermodynamics, composition and chemical equilibrium with problems involving minerals and natural fluids.^[ref]

The connection is useful because a mineral's formula alone does not specify the direction of a reaction. Chemical potentials, activities and the conditions of the surrounding fluid determine which exchanges are thermodynamically favoured.
