Hi Brian, I added the other basis species (Fe2+/3+, Mg, Ca, Na) and replotted. The same result occurs. With Illite(IMt2) a single field and with Illite(Al) multiple mineral fields. I have attached the output files you mentioned. It is weird that in the Illite(IMt2) output it shows the only reaction is illite to illite having a Log K of 0.0. I am assuming this is the problem, but how can it be fixed. By they way, I have been using GWB 8.0.8 and just upgraded to the 8.0.12 version to see if it would help. Same result as above. Thanks, Mchesh9973 K-H_H4SiO4_IMt2_example_output.txt K-H_H4SiO4_Al_example_output.txt

Hello, I am learning how to use Act2 for plotting activity-activity diagrams and for the most part it is pretty straight forward. However, when I swap out a diagram species for another mineral phase (i.e., illite(IMt2) for illite(Al)), sometimes it will plot without the other mineral species and equilibrium boundaries. I will get a single field (i.e. illite(IMt2)) with no other mineral species, while previous mineral species plotted normally with various mineral. All the parameters are the same between the two plots, expect the main mineral species. I get the impression it is a simple fix, but where do I begin? Is this a bug in the program or is there something wrong with the database? I have looked at the database, but nothing stands out to be wrong. I have attached the plot with a single mineral field and the illite data from the database used. Thanks for the help!! mchesh9973 Image_2.pdf Illites.txt
