BQF ternary diagram (Debon + Le Fort 1983)

Description

Assigns data for Debon & Le Fort's BQF ternary diagram into Figaro template (list 'sheet') and appropriate values into 'x.data' and 'y.data'.

Usage

DebonBQF(reference.rocks=TRUE)

Arguments

reference.rocks

logical; should be the ideal rock compositions also plotted?.

Details

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).

Value
