Hi Folks, here is another resource for
mineral formulae recalculation: http://serc.carleton.edu/research_education/equilibria/mineralformulaerecalculation.html
Numerous options are included that also
recalculate end members of feldspars, amphiboles, pyroxenes, garnets, etc.
based on charge balance and cation site occupancy considerations (e.g. also
calculating ferric iron—with all the attendant assumptions and problems). With
permission, I’ll add the spread sheet that Alicia sent to this collection of
Excel recalculation programs.

Dear Moumita,
The attached is a generic excel file that you can use to
calculate any mineral formula on basis of the oxygen’s number. I hope it will be useful for
you,
Best wishes
