Re: Read error for solution models with large multiplicities
Hi David, After running again my benchmarking test this morning, I confirm that the entropy correction term must be -46.1 in Theriak to reproduce Perple_X' results. Sounds like the programs are using a different sign convention for the -TS term. You can find the results of my tests and the database ...

Re: Read error for solution models with large multiplicities
Hi David, Would the splitting of the M0 site into M01 and M02 solve your problem? I have the following model that I benchmarked against Perple_X in 2019.

Re: Errors with newest Theriak-Domino versions on Windows
... and I got the following answer from Capi: The problem described seems irrelevant. If I understand correctly, it just can't write the date into a string. (A work around would be to set the string to some value and RETURN, without looking for the real date and time) One might have to use another b...

Re: Errors with newest Theriak-Domino versions on Windows
Hi Josh and Jacob, We encountered several issues with Erik Duesterhoeft while trying to connect the Windows-version of Theriak-Domino to Bingo-Antidote, but not the specific one you mentionned here. Finally, we decided to recompile Theriak-Domino using Cygwin instead of MinGW. It solves other proble...

Re: Uncertainty on Theriak-Domino
Dear Pan, This is a complicated question and I am afraid there is no simple answer. You are using a bulk rock composition and thermodynamic data and you want to compare the modeled mineral compositions with the observations (e.g. EPMA analysis). There are several sources of uncertainty that need to ...

Re: ragged curves on pseudosection
Hi Jacek, How did you define the number of oxygen in your bulk? I you are using O(?), I suggest you to add a little extra oxygen to avoid minimization issues with the ferric end-members. I would try to calculate the diagram between 550-600 °C and 5000-7500 bar using the following bulk: 1 SI(66.84...

Re: isopleths for elements
Hi Jacek, For help with isoline definition type "i" during "definition of calculation type". For this model, Si(T1) = Si-2. Consequently, Si(T1) ranges from 1 to ~1.5. This can be confusing because in KWM you have two T sites with both a multiciplicity of 2. The first one is only...

Re: Over-prediction of OMPH
I guess I am a little bit confused on the process of acquiring a local effective bulk composition. Once x-ray maps have been produced, was there a certain software you used to acquire modal phase percentage and then calculate a bulk composition based on average mineral composition? Any suggested r...

Re: Over-prediction of OMPH
Hi William, As you probably well know, THERIAK models the stable mineral assemblage at P and T, assuming that the entire system with the given bulk rock composition reacts and achieved equilibrium. However in your sample you have phases such as garnet that are probably metastable at low pressure. S...
