Oxygen Isotope Heterogeneity in the Mesostasis of a Semarkona Group A1 Chondrule
Abstract
Oxygen isotopes in a large group A1 chondrule with compositionally zoned mesostasis show a large spread along a slope one fractionation line with a radial trend of light oxygen increasing toward the edge. The chondrule formation process appears to have produced this trend.
