Suppress Minerals in Kinetic reaction

Ian Hutcheon

Recommended Posts

So... a follow on with the previously described kinetic model. Having resolved getting the runs to terminate, I started suppressing "unwanted" minerals, quartz (waters are close to chalcedony satn) and paragonite. However, when I run the simulations, both minerals still appear? I'm obviously missing something.

Hi Ian,


In Gtplot, does Quartz show up in the "minerals" section, or only in the "mineral saturation" category? If it's the latter there is no problem, since a mineral need not be present to have a saturation index.


Is the output being updated after each run?


Could you post your script so we can take a look?

Hi Brian


I have sent the input file by email...


The file suppresses Quartz (not paragonite, I figure one at a time), but Quartz still seems to show up on GTPLOT.


Interesting difference - with Qz, it takes 230 yrs for Dawsonite to reach EUM, with Qz suppressed it takes 55 years?


BTW Dawsonite kinetic data from Hellevang et al 2010
