Al-Mg Isotopic Systematics in the Angrite Sahara 99555 and the Primitive Achondrite Brachina
Abstract
We report high precision Mg isotopic systematics in Sahara 99555 and Brachina. 26Al-26Mg systematics in Sahara 99555 give a 27Al/26Al ratio of (5.8 +/- 1.9) x 10^-7 at the time of its formation, and are concordant with previously determined 53Mn-53Cr systematics.
