Dr Carrie Soderman

Henslow Research Fellow

I'm interested in many aspects of igneous geochemistry and petrology, particularly understanding magmatic 'critical metal' enrichment. My PhD focused on heavy stable isotope tracers of mantle heterogeneity, combining thermodynamic modelling with the collection of isotope data from ocean island basalts. I am now applying my geochemical background to the study of REE in alkaline-silicate rocks, combining petrology, thermodynamics and geochemical modelling to understand the processes that control the REE budgets in these systems.

Biography

I am a Henslow Research Fellow at Selwyn College and a Postdoctoral Research Associate, as well as the postgraduate representative on the UK's Mineral Deposits Studies Group committee. I completed my PhD in Earth Sciences from the University of Cambridge in 2022, following my BA (Natural Sciences) and MSci (Earth Sciences).
