Description

A matrix of major and minor element data (see below) for the O'Grady pluton, NWT, (NTS map sheet 105I), see ogrady for further details. Additionally, the UTM coordinates and lithology classifications have been removed from the ogrady data frame. This data set is provided so that users can investigate different approaches to the closure problem using the various functions in package ‘rgr’.
