Nb[N]-Th[N] basalt discrimination diagram (Saccani 2015)

Description

Assigns data for Saccani's diagram into Figaro template (list 'sheet') and appropriate values into 'x.data' and 'y.data', the latter also into the matrix 'results'.

Usage

Saccani(plot.txt = getOption("gcd.plot.text"))

Arguments

plot.txt

logical, annotate fields by their names?

Details

The diagram of Saccani (2015), based on NMORB-normalized Nb[N]-Th[N] values (Sun and McDonough 1989), serves for discrimination of geotectonic setting of basalts. The individual fields are illustrated on the original figures of Saccani's work:
