|The olivines and orthopyroxenes in the Morokweng meteorite (plotted as the star symbol) have higher iron contents than most other LL, L, and H chondrites. Axes are labeled Fs and Fa. Fs (ferrosilite, FeSiO3) is the iron-rich end-member of the enstatite-ferrosilite solid-solution series. Fa (fayalite, Fe2SiO4) is the iron-rich end-member of the olivine solid-solution series.)
