elemIso {GCDkit}R Documentation

Binary plot of a WR geochemical parameter vs isotopic ratio

Description

Plots a diagram of a selected whole-rock geochemical parameter vs initial Sr isotopic ratios or initial ε(Nd) for selected samples.

Usage

elemIso()

Arguments

None.

Details

The variable to be plotted as x axis is selected using the function 'selectColumnLabel'. In the specification of the variable can be used also an arithmetic expression, see calcCore for the correct syntax.

The plotted isotopic parameters (y axis) can be one of:

Explanation

87Sr/86Sri

Initial Sr isotopic ratios

143Nd/144Ndi

Initial Nd isotopic ratios

EpsNdi

Initial

ε(Nd)

values

1 stg DM model ages

(Goldstein et al. 1988)

Single-stage DM Nd model ages

1 stg DM model ages

(Liew & Hofmann 1988)

Single-stage DM Nd model ages

2 stg DM model ages

(Liew & Hofmann 1988)

Two-stage DM Nd model ages

The samples can be selected based on combination of three searching mechanisms (by sample name/label, range or a Boolean condition) - see selectSamples for details.

Value

None.
