Patterns 1 and 2 derived from the combined sample in terms of ﹩\mathrm{log}{({\rm{E}}/{\rm{Y}})}_{1}﹩ and ﹩\mathrm{log}{({\rm{E}}/{\rm{Y}})}_{2}﹩ (light blue circles). The red stars show the patterns derived with Eu as the reference element but shifted by ﹩-\mathrm{log}{({\rm{Y}}/{\rm{Eu}})}_{1}﹩ and ﹩-\mathrm{log}{({\rm{Y}}/{\rm{Eu}})}_{2}﹩, respectively, for comparison.
