Formula (repeating unit) | CaTi3+AlSiO6 |
Grossmanite is a very rare mineral of the pyroxene group, [1] with formula CaTi3+AlSiO6. [2] It is the titanium-dominant member. Grossmanite is unique in being a mineral with trivalent titanium, a feature shared with tistarite, Ti2O3. [3] Titanium in minerals is almost exclusively tetravalent. Grossmanite stands for titanium-analogue of davisite, esseneite and kushiroite – other members of the pyroxene group. Both grossmanite and tistarite come from the famous Allende meteorite. [1]
