  • Humite (mineral group) - Wikipedia

    en.wikipedia.org/wiki/Humite_(mineral_group) Chondrodite is the most common member of the humite group. It may contain Ti up to 9.6% TiO 2. Chondrodite from Sterling Hill Mine and Franklin Mine contains zinc to 11.5% ZnO and Mn to 36% MnO, and grades to alleghanyite. The humite minerals commonly alter to serpentine or Mg-rich chlorite and dissolve by weathering, leaving iron oxide residues.
