Project Details
Description
The challenge in deciphering the early evolution of our Solar System lies with a precise and accurate dating of early Solar System processes. Short-lived radionuclides offer precise clocks for these processes. However, the short-lived isotopic chronometers measure only relative time differences, and require a reliable time anchor to map the relative ages onto an absolute timescale. This project seeks to provide precise and accurate U-Pb absolute age anchors for Hf-W and Nb-Zr short-lived isotopic chronometers by integrating U-Pb, Hf-W, and Nb-Zr isotopic data from meteoritic zircon. Additionally, Lu-Hf isotopes in the zircon will be analyzed to constrain the initial state of Hf isotopic evolution in the Earth's crust and mantle.
