    Speciate over x-y in Act2

    ACt2 for forum.ac2gwb_for forum.tdat Thanks again Melika, I still don't understand why the option needs the data for an explanation of what the option does. Can you please explain why it is not the same independent of data set? Thanks, Danielle

    Speciate over x-y in Act2

    Thank you, Malika, Apologies for my delay. I attached one of my ac2 files. This is not the one I was referencing before but the same differences occur. Does the 'speciate over x-y' option not work the same regardless of the file?? Thank you very much, Danielle all FvsCO3 150C ph3.ac2
  3. Hello, I have a question about the mosaics in Act2 and the "speciate over xy" option. I cannot find a good explanation about what it is actually doing to the calculation to make the mosaic output. If this exists and I just have not found it, please link! I was making some mosaics and playing around with the speciate option and got a bit confused on what that option actually does. Does it "take" that element out of the 'soup' to force it to make the most favorable major mineral with that element in concert with the "main minerals"? For example, I swap Ca for apatite in one example, resulting graph looks the same, speciated or not. I swap the Ca for fluorite, speciated over x-y, the result looks different and I get the fluorite/calcite "sub-field" over the other main mineral fields. Ca swapped for fluorite UNspeicated over x-y gives a different graph for the main minerals. So the speciate is changing the Ca availability for the main minerals somehow....but I am confused on what is actually happening. Can someone explain what this option does please? Thank you very much, Danielle
  4. Thank you very much, Brian, Yes, I think this helps, I'll now have to check the papers to see if this info is published. Thank you for responding, Danielle
  5. Howdy, I need to add new minerals to the thermo-database because I am working with some odd-ball ones not in there yet. I am want to clarify that the log Ks that need to be entered with each mineral in Tedit, are the reaction Log K, not the formation log K, correct? Thank you very much, Danielle
