Hi Jia! Thank you so much for the reply back! I'll take a look at that example and also request a demo license for Phase2! Thanks, Nancy

Take 2: I'm using the mosaic diagram under Act2 for the GWB community version software and don't have access to Phase2 or React. 1)One of my goals is to see at what Eh & pH conditions alabandite and pyrite coexist. 2) Another goal is to see at what Eh & pH conditions alabandite, rambergite, and hauerite coexist. Please see attached file! Fe-Mn 25 deg C.jpg.ac2

Thank you for the reply on this post, I'll make another post with a clear intent and add my GWB file.

Been trying to have alabandite and pyrite on the same diagram. Only way is to swap pyrite for Fe(II) and speciate over x-y. However, by doing this, the program only calculates Fe(II) speciation and it does not include Fe(III) species in the diagram. I think the issue here is that the program calculates speciation of Mn vs complexing ions (i.e. Mn vs sulfur species and Mn vs Fe species) but it doesn't calculate speciation between complexing ions themselves (i.e. sulfur vs Fe species) Need advice on how to go about creating an Mn-Fe-S mosaic Eh-pH diagram where I have pyrite and MnS in the same graph without the above issues.
