ex3: Example 3-Mixing

In phreeqc: R Interface to Geochemical Modeling Software

Example 3–Mixing

Description

This example demonstrates the capabilities of PHREEQC to perform a series of geochemical simulations, with the final simulations relying on results from previous simulations within the same run. The example investigates diagenetic reactions that may occur in zones where seawater mixes with carbonate groundwater. The example is divided into five simulations, labeled part A through part E. (A) Carbonate groundwater is defined by equilibrating pure water with calcite at a of 10-2.0 atm. (B) Seawater is defined by using the major-ion data given in table.9. (C) The two solutions are mixed together in the proportions 70 percent groundwater and 30 percent seawater. (D) The mixture is equilibrated with calcite and dolomite. (E) The mixture is equilibrated with calcite only to investigate the chemical evolution if dolomite precipitation is assumed to be negligible. The example can be run using the phrRunString routine.
