Uncovering the secrets of planetary crust formation

Plate tectonics – the movement of Earth's lithosphere – may have been driven originally by the low density of the planet's continental crust. Studies have revealed that this low density is caused by processes that affected the distribution of material throughout the continents. However, gaps remain in our knowledge regarding the characteristics of the crust on other terrestrial planets and how it formed. In particular, could similar physical processes occur on other planets with no plate tectonics? The EU-funded CRUSLID project aims at determining the present-day nature and structure of the crusts and the physical and geological processes leading to crust formation and evolution on stagnant-lid planets.

 


The team



Valentin Bonnet Gibet worked on the formation of the Martian crust and the Martian dichotomy as a PhD student and post-doc. He is now a post-doc at the DLR in Berlin.


Alexandra Le Contellec worked on magma ascent below craters in the crust of Venus, Mars and the Moon, she is now a post-doc at the University of Arizona.


Line Colin is a last year PhD student working on the solidification of the lunar magma ocean.


Swann Rubin is a PhD student working on Mars's and the Moon's seismicity in collaboration with Stephanie Durand and Thomas Bodin.


Madison Borrelli visited our team from ASU for 5 months thanks to a Chateaubriand fellowship. She worked on the spreading of Venus pancake domes as part of her PhD. She is now a post-doc at Georgia Tech.


Kathryn Dodds is a post-doc working on the formation of the lunar crust from a slushy magma ocean.


Hisashi Okuda will start his post-doc in February on the dynamics of slushy mixtures.

News


Congratulations to Alexandra Le Contellec who has very successfully defended her PhD on December 5th 2024 (the first day of the beautiful "Fête des Lumières" in Lyon)!

Congratulations to Valentin Bonnet Gibet who has been awarded an Outstanding Student Presentation Award by the SEDI Section at the AGU fall meeting 2023 for his presentation on the "Formation of Differentiated Rocks on Mars in Absence of Plate Tectonics".

Publications

Want to know more about the physics of lid and crustal growth? Look at our last review article on this subject.

Differentiation of the deep crust forming the Martian highlands might have occurred in absence of plate tectonics by unstable crust growth: see our new publication in JGR.

It took 45 to 200 Myr to solidify the Lunar Magma Ocean if a flotation crust formed: look at Line Colin's new paper in EPSL.

Dark-floored craters that are filled by lava can help constrain the properties and nature of the crustal plateaus of Venus: read Alexandra Le Contellec's new JGR paper on this subject.
