## Example 6–Reaction-Path Calculations

### Description

In this example, the precipitation of phases as a result of incongruent dissolution of K-feldspar (microcline) is investigated. Only the four phases originally addressed by Helgeson and others (1969)–K-feldspar, gibbsite, kaolinite, and K-mica (muscovite)–are considered. The thermodynamic data for the phases (PHASES keyword) are derived from Robie and others (1978) and are the same as for test problem 5 in the PHREEQE manual (Parkhurst and others, 1980). The example can be run using the `phrRunString` routine.
