Error message: "WARNING: loops reached maximum:"
Posted: 30 Oct 2023, 19:07
Hello all
I am trying to use Domino to calculate P-T pseudosections for mafic and ultramafic compositions. I am using the Theriak-Domino version that can be downloaded from github (version 2023.03.06) on Windows computers. The database I am using is td-ds633-ig50-v04 from Doug Tinkham (also available on github). For two separate compositions (below) this error message is showing up: "WARNING: loops reached maximum: 351".
In the case of the mafic composition Domino ran for 9,5 hours and and the output was an almost complete pseudosection. It seems to me that, in the case of the mafic compostion, the problem is linked to assemblages with either two pyroxenes or two amphiboles stable, because, in the "DomOut" file the error message always shows up associated to such assemblages, and, in the output pseudosection the incomplete lines are also associated to such assemblages.
In the case of the ultramafic composition, Domino ran for approximately 1 hour and the output was, apparently, a complete pseudosection. I still plan to run some tests but there are no obvious problems such as discontinuous lines, in a way that might suggest that the error message was of no importance. Nontheless, I would like to understand what is happening.
Any help would be greatly appreciated.
Cheers
Caio
PS: for some reason I am not able to attach the DomOut and Domplt files, but I can send it via some other channel, if necessary. The two compositions I mentioned are given below.
Mafic composition: SI(52.94)TI(1.33)AL(18.17)FE(9.02)MG(11.85)CA(12.8)NA(5.67)K(0.21)CR(0.03)H(1.01)O(?)O(0.48)
Ultramafic composition: SI(37.49)TI(0.08)AL(2.05)FE(5.87)MG(53.37)CA(1.74)NA(0.44)K(0.06)CR(0.3)H(0.2)O(?)O(0.09)
