Chromium (Cr) isotopes play an important role in cosmochemistry and planetary science. They are powerful tools for dating (53Mn–53Cr short-lived chronometry), tracing the origins of the materials (54Cr nucleosynthetic anomalies), and studying the processes involved in volatile element fractionation and planetary differentiation (Cr stable isotopic fractionation). Zhu combines these three approaches by using state-of-the-art mass spectrometry (TIMS and MC-ICP-MS).

This presentation will introduce the application of Cr isotopes for understanding the formation and origin of chondrites, chondrules, and Earth, Moon, Mars, and other terrestrial planets in our solar system.
