Abstract

Stability diagrams depict chemical equilibria between an aqueous solution and minerals. They summarize and illustrate the thermodynamic data related to one element and its associated mineral phases in various geochemical systems. Presented here is a new computation method for constructing such diagrams. The calculation is divided into: 1) thermodynamic data reduction to plane equations in three-dimensional space, 2) computation of the plane intersection with elimination of unstable minerals, and 3) diagram drawing according to a logical scheme, selecting the boundary of each solid phase. This method has the advantages of being efficient and requiring a small core memory, which permits programming and implementation on microcomputers. (Authors' abstract)-C.N.
