Welcome to Vero Le Roux's Laboratory

The mantle represents more than 80% of the volume of the Earth. It controls the thermal state of the planet, drives plate tectonics, and is the reservoir from which magmas are extracted. Variations in mantle composition and temperature controls the location and dynamics of volcanoes at the surface of our planet. Using petrology, geochemistry, field work, experimental petrology, and 3-D imaging of mantle-derived rocks, we aim to answer fundamental questions about the nature of the Earth’s mantle.

May 2022 – New Paper in Nature Geoscience: High water content of arc magmas recorded in cumulates from subduction zone lower crust

Magmatic volatiles (for example, water) are abundant in arc melts and exert fundamental controls on magma evolution, eruption dynamics and the formation of economic ore deposits. To constrain the H2O content of arc magmas, most studies have relied on measuring extrusive products and mineral-hosted melt inclusions. However, these methods have inherent limitations that obfuscate the…

June 2021 – New Paper in Science Advances: Postmelting hydrogen enrichment in the oceanic lithosphere

The large range of H2O contents recorded in minerals from exhumed mantle rocks has been challenging to interpret, as it often records a combination of melting, metasomatism, and diffusional processes in spatially isolated samples. Here, we determine the temporal variations of H2O contents in pyroxenes from a 24-Ma time series of abyssal peridotites exposed along…
