Research Abstract

We have conducted U-Pb dating of various achondrites to understand the timescale of planetary crust evolution and to establish new reliable time anchors. We found that the studied achondrites have a wide range in U-Pb age from 4563 Ma to ca.4440 Ma and that the eucrite Agoult and the ungrouped achondrites Ibitira and Northwest Africa 6704 can potentially serve as the time anchors. We have further investigated the Nb-Zr isotope systematics of these meteorites. The results allow us to define the Solar System initial 92Nb abundance and to evaluate its uniformity.
