Our research is structured around the study of geochemical transfers and fluid-mineral-living interactions within the crust-hydrosphere-atmosphere system, as well as crystal nucleation and growth and the properties of nano- and geo-materials. This interdisciplinary research is at the interface between geochemistry, mineralogy, physical chemistry, microbiology, metallogeny and materials science.
Leader: Gleb POKROVSKI
We study geochemical mechanisms and transfers over a wide range of spatial and temporal scales, from the atom to the field, in various contexts such as fluid-mineral-living interactions, nucleation and crystal growth, magmatic hydrothermal systems, and properties of nano- and geo-materials.
- Resources
- Energies
- Climate change
- Materials
The fundamental experimental and numerical models developed are used in natural contexts from the deep lithosphere to permafrost, but also in more applied fields such as mineral and energy geo-resources, mineral CO2 sequestration, corrosion in nuclear power plants, or various uses of nanomaterials.
- Experimentation, in situ measurement
- Synthesis, analysis
- Spectroscopy, modeling
- Sampling, monitoring
Scientific result
How can uranium isotopes help trace the history of the Earth’s oxygenation?
A recent study reveals the existence of a uranium isotopic signature specific to oxygen-depleted environments. This discovery could help to better understand the history of the co-evolution between animal life […]

Questioning our knowledge of the chemistry of the early oceans
An international team involving a CNRS-INSU laboratory has determined the isotopic fractionations associated with greenalite, a mineral of the silicate class rich in ferrous iron (Fe2+), and has thus evaluated […]
