Collection of six binary diagrams, based on major elements chemistry, developed by Maniar & Piccoli (1989) for tectonic discrimination of granitic rocks. Shand's (1943) diagram is also used. Diagrams are defined as follows:
| x axis | y axis | 
| SiO2 | K2O | 
| SiO2 | Al2O3 | 
| SiO2 | FeO(T)/(FeO(T)+MgO) | 
| 100*MgO/(Al2O3+Na2O+K2O+FeO(T)+MgO) | 100*FeO(T)/(Al2O3+Na2O+K2O+FeO(T)+MgO) | 
| M and F proportion in the AFM system | |
| 100*CaO/(Al2O3+Na2O+K2O+FeO(T)+MgO+CaO) | 100*(FeO(T)+MgO)/(Al2O3+Na2O+K2O+FeO(T)+MgO+CaO) | 
| C and F proportion in the ACF system | |
| A/CNK (molar) | A/NK (molar) | 
Abbreviations used in diagrams represent granitoids from following geotectonic environments:
| IAG | Island Arc Granitoids | 
| CAG | Continental Arc Granitoids | 
| CCG | Continental Collision Granitoids | 
| POG | Post-orogenic Granitoids | 
| RRG | Rift-related Granitoids | 
| CEUG | Continental Epeirogenic Uplift Granitoids | 
| OP | Oceanic Plagiogranites | 
 
 
Peralkaline, Metaluminous and Peraluminous rocks are defined in the last (Shand's) diagram.
This function uses the plates concept. The individual plots can be selected and their 
properties/appearance changed as if they were stand alone Figaro-compatible plots.
 
See Plate, Plate editing and 
figaro for details.
