Cabanis + Lecolle (1989) La/10-Y/15-Nb/8

Description

Assigns data for a La/10-Y/15-Nb/8 ternary diagram into Figaro template (list 'sheet') and appropriate values into 'x.data' and 'y.data'.

Usage

Cabanis()

Arguments

None.

Details

The ternary plot La/10-Y/15-Nb/8 designed by Cabanis and Lecolle (1989) serves for distinguishing magmas that have originated (1) at orogenic, compressive, destructive plate boundaries (calc-alkaline, closer to the La apex and tholeiitic, closer to the Y apex); (2) in anorogenic, distensive inter-plate domains (including NMORB/EMORB and alkaline rocks); and, in between, (3) in either compressive or distensive, intra-continental, late- to post- orogenic zones. Y/Nb serves here as the "alkalinity index" and La/Y as the "calc-alkaline index". See the original paper for details.

The diagram can also serve for recognition of magmas contaminated by continental crust or resulting from magma mixing.
