High Precision Al-Mg Chronology of Chondrules in Unequilibrated Ordinary Chondrites
Abstract
New analyses of UOC chondrules with a range of mesostasis compositions indicate a restrict range of their formation ages from 1.8 to 2.2 Ma after CAIs, much shorter than 1.5-3 Ma and 0-4 Ma estimated from previous Al-Mg and Pb-Pb ages, respectively.
