Suite of four diagrams for discrimination of geotectonic environment of granitoid rocks, proposed by Pearce et al. (1984). It is based on combination of five trace elements (namely Y, Nb, Rb, Yb and Ta).
Following geotectonic settings may be deduced:
Abbreviation used | Environment |
ORG | Ocean Ridge Granites |
VAG | Volcanic Arc Granites |
WPG | Within Plate Granites |
COLG | Collision Granites |
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.
