A study of Mg and K isotopes in Allende CAIs: Implications to the time scale for the multiple heating processes

— The measurements of magnesium and potassium isotopic compositions of refractory minerals in Allende calcium‐aluminum‐rich inclusions (CAIs), 7R‐19–1, HN3–1, and EGG3 were taken by secondary ion mass spectrometry (SIMS). The 7R‐19–1 contains 16O‐rich and 16O‐poor melilite grains and define a single...
