Biplot of principal component analysis
Biplot of principal component analysis of soil elemental composition data. Background and enriched samples are denoted. Colored points are from potentially enriched soils at mine sites, and black points are from unmined background sites. The effect of different elements on the analysis is shown by the rays, which are labeled to identify the elements.
