Assigns data for 
5Fe2O3t - Na2O+K2O - 5(CaO+MgO)  
ternary diagram into Figaro template (list 'sheet') 
and appropriate values into 'x.data' and 'y.data'.
Grebennikov()
None.
The ternary plot 5Fe2O3t - Na2O+K2O - 5(CaO+MgO) of Grebennikov (2014) serves for classification of A-type granites and related felsic volcanic rocks (SiO2 > 67 wt.%).
