Wood {GCDkit}R Documentation

Wood (1980)

Description

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

Usage

    Wood(ident = getOption("gcd.ident"), 
    plot.txt = getOption("gcd.plot.text"))

Arguments

ident

logical, identify?

plot.txt

logical, annotate fields by their names?

Details

A series of triangular diagrams with apices Th-Hf/3-Ta, Th-Hf/3-Ta and Th-Zr/117-Nb/16, proposed by Wood (1980).

Following fields are defined:

IAT Island-arc Tholeiites
CAB Calc-alkaline Basalts
N-MORB N-type Mid-ocean Ridge Basalts
E-MORB E-type Mid-ocean Ridge Basalts
WPT Within-plate Tholeiites
WPA Alkaline Within-plate Basalts

Value

sheet

list with Figaro Style Sheet data

x.data, y.data

Th, Hf/3 and Ta in ppm recalculated into two dimensions

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.
