elemIso {GCDkit} | R Documentation |
Plots a diagram of a selected whole-rock geochemical parameter vs initial Sr isotopic ratios or initial ε(Nd) for selected samples.
elemIso()
None.
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:
Menu item | 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.
