Assigns data for a Meschede's (1986) triangular 
diagram into Figaro template (list 'sheet') and appropriate values 
into 'x.data' and 'y.data'.
    Meschede()
Triangular diagram with apices Zr/4, 2Nb and Y, proposed by Meschede (1986). The plot serves primarily for tectonic discrimination of tholeiitic basalts.
 
 
Abbreviations used in diagram represent following geotectonic settings:
| AI-AII | Within-Plate Alkaline Basalts | 
| AII-C | Within-Plate Tholeiites | 
| B | P-type Mid-Ocean Ridge Basalts | 
| D | N-type Mid-Ocean Ridge Basalts | 
| C-D | Volcanic Arc Basalts | 
| sheet | list with Figaro Style Sheet data | 
| x.data, y.data | Zr/4, 2Nb and Y values recalculated into two dimensions |
