Figure 9.04. REE Diagram for Several Rock Types . Chondrite normalized REE values for average rock compositions are shown here with lines connnecting the points to display a REE pattern. The rock types are average granite (red, Li, 2000), continental crust (orange, Rudnick and Gao, 2005), average andesite (blue, Li, 2000), average basalt (black, Li, 2000), and MORB (green, Gale et al., 2013).
