Titanomagnetite an overview ScienceDirect Topics
网页V. Chandler, in Treatise on Geophysics (Second Edition), 2015 11.05.3.1.2 Titanomagnetite Titanomagnetites are common magnetic minerals in igneous and metamorphic rocks. Titanomagnetites (Fe3 −x Ti x O 4, 0 ≤ x ≤ 1) form a complete solid solution above ~ 923 K between end-members magnetite (Fe3 O 4, x = 0) and ulvöspinel (Fe 2 TiO 4, x = 1).
