Pyroxene group. The V analogue of davisite (Sc), esseneite (Fe³⁺), grossmanite (Ti³⁺), and kushiroite (Al). Contains both trivalent and tetravalent titanium admixture. A complete solid solution with grossmanite and davisite is possible.

Known as a synthetic phase - Ca(V,Al)AlSiO₆.

Chemically somewhat similar to beckettite and mukhinite.

A new refractory phase in a Ca-Al-rich inclusion (CAI); formed rather in reducing conditions.
