Enter your fluid composition on the Basis pane Set dissolved concentrations in units of your choice Set temperature of your system Click to add new entries

On the Results pane, click Run to execute the calculation. Open text file Plot results with Gtplot

“View Results” opens text file Oversaturated minerals Undersaturated minerals

“Plot Results” opens Gtplot Set X and Y axes Set “Variable type” to “Mineral saturation” Only consider minerals with silica

Rerun your model to figure the new equilibrium state You can set your fluid in equilibrium with one or more minerals by swapping them into the basis Kaolinite swapped in for Al+++ Set an arbitrary mass or volume Swap Hematite in for Fe++ Rerun your model to figure the new equilibrium state

The new fluid is distinct from the previously defined fluid. We set our new fluid in equilibrium with Hematite and Kaolinite, so their saturation indices should be 0
