You can use solvocalc program

Dear Dr Adel, I don't have Solvocalc. Will you please share any link/ excel file or some format so that I can use it?

Or, can you help me in getting the details from where I can procure the software?

Thank you

Hi, if i find new solvocalc version in my pc, i send it for you.

If you study granitic rocks, for S-type granite 5-7 kbar and I-type 10-15 kbar pressure is suitable.

Hello, yes. Pressure for hydrothermal is 1 kbar.
