PearceGranite {GCDkit}R Documentation

Pearce et al. (1984)

Description

Assigns Figaro templates to Pearce's geotectonic diagrams for granitoids into the list 'plate') and appropriate values into the list 'plate.data' for subsequent plotting.

Usage

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

Arguments

plot.txt

logical, annotate fields by their names?

Details

Suite of four diagrams for discrimination of geotectonic environment of granitoid rocks, proposed by Pearce et al. (1984). It is based on combination of five trace elements (namely Y, Nb, Rb, Yb and Ta).

Abbreviation used Environment
ORG Ocean Ridge Granites
VAG Volcanic Arc Granites
WPG Within Plate Granites
COLG Collision Granites

Note

This function uses the plates concept. The individual plots can be selected and their properties/appearance changed as if they were stand alone Figaro-compatible plots. See Plate, Plate editing and figaro for details.
