Generate Mineral Stability Diagrams using Act2


Recommended Posts

I am trying to generate activity-activity plots for the following reaction:
Andalusite+Celadonite = Margarite + Muscovite
I have calculated Thermodynamic data which includes the Log K for this reaction using SUPCRT92 (Johnson et al 1992). How do I incorporate this data within Act2 to generate a stability diagram that represents the activity of my reaction?? I have attached a sample of the type of diagram I need to plot.

Please Help!!

Hello Tanzil,

 

You can easily modify thermodynamic datasets in the GWB using TEdit (under the support tab on the GWB dashboard). It's always a good idea to start by opening an existing dataset and saving it to a different name before modifying it. For more information, see the TEdit section in the GWB Essentials Guide (you can access PDFs of the user's guides from the Help menu of any GWB program, or from the Docs pane of the GWB dashboard). You can also view tutorials on how to edit thermo datasets here. Once you have completed your thermo dataset you can load it into Act2, go to File ->Open->Thermo Data... (or Ctl+T) to select the thermo dataset you would like the program to reference.

 

Kind regards,

Hi Katezat,

 

I am very glad to read your answer. I am learing GWB for the modeling need in geology. I was still confused by the function of SUPCRT92, GWB has its own thermodynamic datasets, why we still need supcrt92 to generate the new dataset, and do you know any tutorial about how to use SUPCRT92.

Thank you very much!

 

Best Regards

Hi Tanzil Deshmukh,

I noticed that you use the SUPCRT92 to generate a thermodynic dataset. I don't know how to use this software to generate a dataset, so do you have any tutorials to show the process.

Best Regards.
