Spinelan overview ScienceDirect Topics
End-member spinel MgAl 2 O 4 is probably the most universal of all CAI minerals. It occurs in virtually every kind of CAI and in virtually every chondrite type. The chemical variations of CAI spinel were reviewed in detail by Brearley and Jones (1998) and consequently only a few points need to be emphasized here. The first is that where spinel compositions do depart (typically enriched FeO) significantly from the ideal magnesium
