Evidence of ^(26)Mg Excess in Hibonite from Murchison


We report Mg isotopic analyses on a hibonite inclusion from Murchison (CM), named the Blue Angel for its distinct color, and discovered by R.H. Becker. Petrographic, mineralogic, and chemical information is provided in a companion abstract (Armstrong et al., 1980). Hibonite is important as it has the highest estimated condensation temperature for major element oxides (Blander and Fuchs, 1975), may have a high Al/Mg ratio, and may be chemically resistant to alteration.
