1. (a) 2D SOM map and Au component plane with division of final catchment clusters and (b) mean code-vector ratios for cluster Au concentration.
(a) 2D SOM map and Au component plane with division of final catchment clusters and (b) mean code-vector ratios for cluster Au concentration. Five clusters display higher that one standard deviation from the mean (dashed line) code-vector ratio. For interpretation of the references to colour in this figure, the reader is referred to the online version of this article.
