Continental rifts result from the simultaneous action of shallow processes such as the thinning of the lithosphere, and deeper processes related to the dynamics of the mantle. The …
Among the various university courses I took for my geoscience degree, volcanology and structural geology motivated me by far the most. Volcanoes and deformed rocks are indeed …
Oceanic detachment faults play a central role in accommodating the plate divergence at slow-ultraslow spreading mid-ocean ridges. Successive flip-flop detachment faults in a …

The fraction M of plate separation accommodated by magma emplacement at mid-ocean ridges has been recognized as the main control on seafloor spreading modes, yet the …
Mantle serpentinization influences the rheology of altered peridotites and the global fluxes of energy and volatiles, the generation of seafloor and sub-seafloor chemolithotrophic life, and …

The redox state of hydrothermal fluids on mid-ocean ridges, which is indirectly affected by the depth of hydrothermal circulation and crustal permeability, plays an important role on the …

The thermal state of mid-ocean ridges exerts a crucial modulation on seafloor spreading processes that shape~ 2/3 of our planet's surface. Standard thermal models treat the ridge …
Abstract The Indomed-Gallieni supersegment (46-52° E) of the Southwest Indian Ridge (SWIR) has been of interest as a melt-rich endmember of ultraslow spreading mid-ocean …
Melt supply at the ultraslow‐spreading Southwest Indian Ridge (SWIR) has been shown to vary from nearly amagmatic, leading to ultramafic seafloor, to magmatically robust …
