DebonBQF | R Documentation |
Assigns data for Debon & Le Fort's BQF ternary 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 BQF diagram as proposed by Debon and Le Fort (1983) expresses balance of three main groups of rock-forming minerals, dark minerals (B), quartz (Q) and feldspars with muscovite (F).
Parameters for the diagram are calculated by the function 'DebonCalc
'.
All of them are based on millications (1000 gram-atoms per 100 grams) and named
as follows:
Q(quartz)
B(dark m.)
F(feldsp)
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) or (1988).
