Uranium isotope ratios of Muonionalusta troilite and complications for the absolute age of the IVA iron meteorite core

Brennecka, Gregory A; Amelin, Yuri; Kleine, T


The crystallization ages of planetary crustal material (given by basaltic meteorites) and planetary cores (given by iron meteorites) provide fiducial marks for the progress of planetary formation, and thus, the absolute ages of these objects fundamentally direct our knowledge and understanding of planet formation and evolution. The lone precise absolute age of planetary core material was previously obtained on troilite inclusions from the IVA iron meteorite Muonionalusta. This previously...[Show more]
