Assigns data for SiO2 vs. FeOt/MgO diagram 
into Figaro template (list 'sheet') and appropriate values into 
'x.data' and 'y.data'
Miyashiro()
Diagram in SiO2 vs. FeOt/MgO space, proposed by Miyashiro (1974), defines the following fields:
Tholeiite Series
Calc-alkaline Series
 
 
As the boundary was defined by Akiho Miyashiro as straight line passing through two specific points, no limits of diagram validity for ultrabasic and high-silica rocks were given. Thus, the boundary implemented in GCDkit script spreads from FeOt/MgO=0 to SiO2=100 %.
