Petrology and Geochemistry

Group

Petrology, Geochemistry and Geochronology (PGG)

My research relates to the compositional evolution of the Earth’s mantle through the study of mafic and ultramafic terranes and xenoliths. I use in-situ/solution trace-element and isotope geochemistry (Sr-Nd-Hf-Os) and petrological modelling to understand the genesis of mantle-derived magmas, their sources and differentiation processes. I am especially interested in elemental mobility and isotopic fractionation in the sub-arc mantle and the role of melt-peridotite interaction during the formation of pyroxenites.
