Lithophile elements are those that remain on or close to the surface because they combine readily with oxygen, forming compounds that do not sink into the Earth's core. The lithophile elements include: Al, B, Ba, Be, Br, Ca, Cl, Cr, Cs, F, I, Hf, K, Li, Mg, Na, Nb, O, P, Rb, Sc, Si, Sr, Ta, Th, Ti, U, V, Y, Zr, W and the lanthanides or REEs (Rare Earth Elements).

Most of these elements are so oxyphile that the most stable gas species, even in the reducing solar gas is MO or MO 2 rather than M 0. Ti is calculated to condense from TiO in the gas into CaTiO 3 perovskite, starting at 1583 K with a T 50 of 1565 K.
