About

The team develops innovative analytical methods and approaches, using trace elements, isotopes and petrology, to address big-picture questions about Earth’s formation and evolution, as well as interactions between deep Earth (rocky) reservoirs and the exosphere. As part of the AuScope Geochemistry Network (AGN), our work is intertwined with the AuScope Earth Composition and Evolution program (ECE) and EarthBank initiative.

Facilities

The ANU SHRIMP facility offers high-resolution ion microprobe analyses, allowing for precise measurements of stable isotopes, volatile elements, trace elements, and uranium-lead dating in solid materials.

Projects

Olivine is the most abundant mineral in the Earth’s mantle. However due to its tight crystal lattice, it is challenging to extract geochemistry information out of mantle and magmatic olivines. Lets go to the ultra-trace elements
