Q'-ANOR diagram (Streckeisen + Le Maitre 1979)

Description

Plots normative Q'-ANOR diagram of Streckeisen & Le Maitre (1979).

Usage

    QANOR(mesonorm=NULL,new=TRUE)

Arguments

mesonorm

numeric, a matrix containing normative minerals calculated, most appropriately, by the function Mesonorm.

new

logical, is a new plotting window to be opened?

Details

This function plots Q'-ANOR diagram of Streckeisen & Le Maitre (1979) where Q' = 100Qz/(Qz + Or + Ab + An) and ANOR = 100An/(Or + An) based on eine bessere Mesonorm for granitoids of Mielke & Winkler (1979).
