Question: Olivine is a magnetic mineral abundant in the Martian soil. Important olivine occurs in the pseudo-binary solid solution between the isostructural magnesium silicate (forsterite) and iron silicate (fayalite); Consider fayalite which adopts space group Pnma (D162h) (#62) with lattice constants a = 0.4816, b = 1.0469, c = 0.6099 nm.
