Measurements of both 53Cr/52Cr and 54Cr/52Cr ratios with a precision of 10-4 in Allende inclusions display widespread chromium isotopic anomalies which are in the range of 5⋅10-4. Instrumental mass fractionation precludes specific identification of the affected isotopes, but there are strong arguments favoring excesses in 54Cr and a hint of a very small deficit in 53Cr (≈10-4). These samples also display excesses in 50Ti and no significant effect in nickel isotopes.
