Description

tectonic discrimination diagram for granites

Usage

YNb(Y = NULL, Nb = NULL, show.labels = TRUE, xlim = NULL, ylim = NULL, ...)

YNbRb(
  Y = NULL,
  Nb = NULL,
  Rb = NULL,
  show.labels = TRUE,
  xlim = NULL,
  ylim = NULL,
  ...
)

YbTa(Yb = NULL, Ta = NULL, xlim = NULL, ylim = NULL, show.labels = TRUE, ...)

YbTaRb(
  Yb = NULL,
  Ta = NULL,
  Rb = NULL,
  show.labels = TRUE,
  xlim = NULL,
  ylim = NULL,
  ...
)

Arguments

Y	vector with Y concentrations (ppm)
Nb	vector with Nb concentrations (ppm)
show.labels	logical. If TRUE, labels the polygonal fields with their respective tectonic affinities.
xlim	x-axis limits
ylim	y-axis limits
...	additional arguments to the generic points function.
Rb	vector with Rb concentrations (ppm)
Yb	vector with Yb concentrations (ppm)
Ta	vector with Ta concentrations (ppm)

Value

a vector with tectonic affinities
