Plate III Elemental abundance in the Earth's crust. Greenish areas
indicate the rock forming elements, and yellow areas denote the least
common metals. The highlighted elements, zinc and indium, are
discussed in the text. Data of this kind are found in many sources; this
particular diagram was obtained from Berry (2010).
