Hello, i have been trying to do analysis with Phreeqc software on soil carbon capture i can't find the minerals Labradorite, Augite in any of phreeqc database. It's affecting my analysis and i keep having errors. And the mineral K-feldspar as well.

Can you inform me how to input this non-ideal minerals in the equilibrium phases block ?

This is my input data i would appreciate it if you inform me on how to resolve the errors in the output data.
