Although we have a wide range of research interests, the majority of research in EPIC focuses on the chemistry, conditions, and timescales of magma formation as pertain to planetary differentiation and volcanic hazards.
To explore these questions, we use a combination of:
Check out this article on some of the exciting research topics in Experimental Petrology, many of which we explore in EPIC.
To explore these questions, we use a combination of:
- One atmosphere, piston cylinder and multi-anvil experiments to generate magma in the laboratory
- In-situ analytical techniques such as electron probe, SIMS/SHRIMP, NanoSIMS and LA-ICPMS to examine samples generated in the lab and collected in the field
- Quantitative chemical models to integrate experimental and analytical observations
