Abstract
- Results are presented from measurements of O, Mg, and Ti isotopes and the abundances of Mg, Ca, Sc, Ti, V, Sr, Y, Zr, La, and Ce in 26 individual corundum grains from the Murchison CM2 chondrite. The results provide further evidence for live Al-26 in the early solar system and set strict upper limits on the amounts of fossil Mg-26. The analyses suggest that corundum in this chondrite formed from two components with live Al-26 and a mass fraction of 43 percent dead Al.
