A new calcium-aluminate from a refractory inclusion in the

Abstract The first meteoritic occurrence of CaAl4O7 is described from a Ca-Al-rich inclusion (CAI) in the Leoville carbonaceous chondrite. This CAI consists mainly of gehlenitic melilite, spinel, perovskite, and hibonite. CaAl4O7 is a minor component and occurs within melilite preferentially in portions rich in perovskite. The CAI is enveloped by a succession of three rims (from inside out
