Description

Discriminants for MORB, ocean island, and a variety of arc-type basalts

Usage

NbLaYb(
  Nb = NULL,
  La = NULL,
  Yb = NULL,
  xlim = NULL,
  ylim = NULL,
  show.labels = TRUE,
  short = FALSE,
  ...
)

ThNbLaYb(
  Th = NULL,
  Nb = NULL,
  La = NULL,
  Yb = NULL,
  xlim = NULL,
  ylim = NULL,
  show.labels = TRUE,
  short = FALSE,
  ...
)

Arguments

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

Value

a vector with tectonic affinities
