Hi again, sorry, I just realized, that I had some misconceptions concerning this problem as well. That is, I confused where the SI(T1) is coming from, and the PHNG   SI(T1)   1    0   0.49   0.01 will not work. However, the 3.0 - 3.49 do not work, because SI(T1) is not Si p.f.u.. Sorry for the confu...

Hi Jacek,

you get empty diagrams, because the range of 3.0 - 3.49 you want to see is Silicum per formula unit, but what you tell the program to plot (SI(T1)) is the amount of octahedral Si. I would suggest you use the line:

PHNG     SI(T1)    1       0      0.49      0.01

Dear Doug,

thank you for your answer, it is very helpful.

Best,

I don't think you will get problems by introducing the OHM buffer to the dataset, because the only thing it does is setting the oxigen activity as a function of the buffer. However (as I just recently had a discussion about the usage of OHM buffers) I heard that if you do not observe both hematite a...

What bothers me often and where I have absolutely no knowledge about is, how much can I alter the datasets without producing nonsense? That is, my main concern is, lets say in the Holland & Powell dataset, what if I e.g. don't trust the solution for Mn in biotite: am I allowed to exclude the Mn ...

In the JUN92.bs dataset (Behrmann dataset) which comes with the Dom.-Ther. software, if I remember correctly it's mainly the phases rutile and ilmenite which can incorporate Ti. There is e.g. no Ti in biotite, so having Ti in your bulk chemistry will result in the growth of rutile/ilmenite-7etc. The...

Although I never used it for calculating stochiometry, but would calculating a pixelmap be a way of doing this? The pixelmap results contain the moles of each phase at every pixel in your P-T (or wathever) space. From this one could calculate the change in moles of phases from pixel to pixel.

Have you set the right path in the 'start.bat' file within the \Working directory?

Although having several theriak-dominos run in parallel has the advantage that this way they run on different threads, I prefer the batch script (with the reason that I think it lets you keep a better overview over your calculations).
