Re: Floating 'K' in assemblage
Hi Blakelee, Thanks again for all the help. I wasn't aware that the order of the elements on the THERIN input affected the outcome of the results. I tried the first input you listed (0 MN(0.116)NA(3.914)CA(1.358)K(4.952)FE(5.769)MG(3.373)AL(24.839)SI(55.019)TI(0.660)H(60)SI(30)O(?) *) and unfortunat...

Re: Floating 'K' in assemblage
Hi Blakelee, Thanks for trying and I am glad that you were successful with it. I noticed that you used a O(?) in the input. I have never understood why a question mark is used rather than calculating out the O. Could you explain this for me? And if it has to do with never knowing the exact 'O' conte...

Re: Floating 'K' in assemblage
Hi Blakelee, Thanks for the response. Below are my calculations (bulk+THERIN input; it wasn't letting me attach the .xls file I had it on). I have added Qz and H2O to the calculation, as Qz was texturally stable throughout the history of the sample, as was white mica. I also tried to do the calculat...

Floating 'K' in assemblage
Hello All, I was recently trying to model a high-pressure metapelite and within all the assemblages I get a floating 'K' (e.g., GRT (2)WM BI14 K H2O q ru). I am using the td-ds62-mp50-03 data set and am unable to find 'K' as an abbreviation for anything. Does anyone know what this means? Thanks! Will

Re: Over-prediction of OMPH
Hi All,
Thanks for the very helpful tips. The addition of O to the bulk worked well and I am getting much better results. As for determining the effective bulk composition, the process is something I am new to and will try to work with.
Thanks again!
William

Re: Over-prediction of OMPH
Hi Pierre, Thank you for the response. The garnet in the garnet-epidote-amphibolite has a relatively flat compostional zoning profile. The strongest zoned phase seems to be amphibole, which goes from a more pargasitic composition to hornblende in the rim. I guess I am a little bit confused on the pr...

Over-prediction of OMPH
Hi All, I'm new to the forum and glad it was created. I am having an issue and wanted to see if anyone has had similar issues and has a remedy. I am trying to construct diagrams for garnet-epidote-amphibolite samples. The samples contain amp, ep, grt, pg, ph, rt, ilm, ttn, qz, ab ± hm. When constru...
