Formula:
Cax(Al,Si)1-xO3
One of a few phases found within Ca-Al inclusions in moissanite (-4H, -15R, and -6H) from Turkey, that include gehlenite and Unnamed (Ca-Al-(Si) oxide II), Unnamed (Ca-Al-(Si) oxide III), Unnamed (Ca-Al-(Si) oxide IV) and Unnamed (Ca-Al-Si oxide).
As lamellae coexisting with dmisteinbergite and Unnamed (Ca-Al-(Si) oxide II).
Possibly a perovskite-structured phase as its Al2O3 content is said to be within the "upper limit of alumina solubility in Ca-perovskite".
Compare yoshiokaite; dmitryivanovite, krotite, grossite, hibonite.
