Gregory Yaxley

Prof Gregory Yaxley is a Professor at the Research School of Earth Sciences, Australian National University. His research focuses on mantle processes, carbonatite magmas, and lithospheric stability. He holds qualifications including a BSc (Hons), Dip. Ed., and PhD. Key research interests include peridotite metasomatism, mantle dynamics, and kimberlite systems. Over 83 publications since 1993 highlight his work on xenolith geochemistry, experimental petrology, and cratonic architecture. Current projects investigate critical minerals in Australian deposits and carbonatite formation mechanisms. Active supervisory roles support graduate research in mantle petrology and magmatic systems.

Research Interests

Prof Yaxley explores cratonic lithosphere stability through mantle xenolith studies and investigates carbonatite magmas as critical mineral sources. Major themes include metasomatic controls, melt-rock interaction, and high-pressure experimental petrology. His work bridges geochemistry and geophysics to model mantle processes.
