Melting and melt percolation processes
NSF funded. Using fieldwork, petrology and geochemistry, we develop tracers of melting and melt percolation processes in continental and oceanic lithosphere. For example, we investigate how ophiolitic peridotites may record the path of fluid-rich materials in supra-subduction environments.
Halogen budget of peridotite mantle
NSF funded. Using fieldwork, petrology and geochemistry, we develop tracers of melting and melt percolation processes in continental and oceanic lithosphere. Lately, we have been investigating how ophiolitic peridotites record the path of fluids in supra-subduction environments.
Mélange-peridotite interactions / Arc magmatism
We are performing high-pressure high-temperature experiments to investigate the role of melange rocks in the generation of arc magmas.
NSF funded. Using geochemistry and experimental petrology, we aim to understand how heterogeneities develop in the Earth’s mantle (Lherz Massif). In addition, we use MORBs and other mantle-derived melts to determine the geochemical signature of mantle heterogeneties.
Serpentinization and volume increase
NSF funded. Using a novel combination of hydrothermal experiments and micro-CT, we are investigating volume increases during serpentinization.
Olivine-hosted melt inclusions as tracers of magmatic processes
NSF funded. Using a novel combination of Raman, SIMS and x-ray micro-computed tomography, we investigate magma ascent rates and magma chamber depths in a variety of systems (Iceland, Antartica).
