DebonBMgNo | R Documentation |
Assigns data for Debon & Le Fort's B vs. Mg/(Fe + Mg) diagram into Figaro template (list 'sheet
') and
appropriate values into 'x.data
' and 'y.data
'.

logical; should be the ideal rock compositions also plotted?. |
The B vs. Mg/(Fe + Mg) diagram was proposed by Debon and Le Fort (1983) to distinguish magnesian and ferriferrous associations.
Parameters for the diagram are calculated by the function 'DebonCalc
'.
All of them are based on millications (1000 gram-atoms per 100 grams).
B = Fe + Mg + Ti [maficity]
Mg/(Fe + Mg) [Mg number, Fe is total iron]
Optionally, if, reference.rocks = TRUE
, twelve average chemical compositions of
common igneous rocks are also plotted, as follows:
label | plutonic rock |
go | gabbro |
mzgo | monzogabbro |
mz | monzonite |
s | syenite |
dq | quartz diorite |
mzdq | quartz monzodiorite |
mzq | quartz monzonite |
sq | quartz syenite |
to | tonalite |
gd | granodiorite |
ad | adamellite |
gr | granite |
For details, see Debon & Le Fort (1983) and (1988).
