A multidisciplinary team to characterize and understand the sources and transfers of matter and heat in oceanic and continental lithospheres.
Leaders: Stéphanie DUCHÊNE and Mary-Alix KACZMAREK
Our goal is to produce knowledge on the coupled evolution of the crust and mantle, from crystal to lithosphere, and from ocean to continent, relying on the skills of team members in paleomagnetism, structural geology, metamorphic and magmatic petrology.
- What is the spatiotemporal distribution of magmatic and hydrothermal fluids in space and time?
- What are the consequences of matter and heat transfers on the differentiation and deformation of lithospheres?
- How does geological history and geodynamics condition the distribution of mineral and geothermal resources? How to use resources as geological markers?
- What are the respective roles of magmatic differentiation and impacts in the evolution of planets and planetary bodies?
- What has been the impact of magmatic processes on Earth’s climate history?
- Oceanic lithospheres
- Western Africa
- South America
- European mountain belts
- Field observations
- Structural geology
- Petrology
- Geochronology
- Quantification and geophysical and geochemical modeling
