Simulation of Geochemical Reactions by Equilibrum Step Codes

摘要

This report describes the principles, applications, and limitations of the present state of the art of equilibrium step codes. The discussion is oriented toward concerns of the user of such codes, and toward applications of the codes to study of low-temperature, aqueous, geochemical systems; detailed discussion of computational methods is avoided. Primary emphasis is directed to a code devised recently by T. Wolery at Northwestern University and the Lawrence Livermore Laboratory of the University of California. This code is in use at LBL in theoretical studies of rock-water interactions near hypothetical nuclear waste depositories. (ERA citation 04:035917)
