Hi! Does anybody know if is it possible to add a mineral to the program database? I would like to add crandallite, CaAl3(PO4)(PO3OH)(OH)6. I am trying to generate mineral phase diagrams that include crandallite and apatite. According to the reference attached (Dill, 1991), crandallite should be formed in the presence of HPO4--, Al+++ (Gibbsite), and Ca++ in an aqueous solution (25º C and 1 atm). However, it seems crandallite is missing in the program database. Cheers 1991 Dill et al - Chemistry and origin of vein-like phosphate mineralization, Nuba Mountains (Sudan).pdf
