Fig. 2: Chondrite-normalized rare-earth element spider diagram for igneous rocks from Haib.

The normalization values are from ref. ⁸⁴. Inset is Dy/Yb versus SiO₂ diagram, and the fractionation trends of amphibole and garnet are from ref. ⁴². Data for the igneous rocks (LOI ≤ 2 wt.%) from the western Richtersveld Magmatic Arc were compiled in ref. ¹⁵.
