Titanomagnetites are common magnetic minerals in igneous and metamorphic rocks. Titanomagnetites (Fe 3 −x Ti x O 4, 0 ≤ x ≤ 1) form a complete solid solution above ~ 923 K between end-members magnetite (Fe 3 O 4, x = 0) and ulvöspinel (Fe 2 TiO 4, x = 1). The compositional parameter x gives the fraction of ulvöspinel ((1 −x)Fe 3 O 4 xFe 2 TiO 4) or the mole fraction of Ti 4 + in a ...
