Abstract Ocean-Continent Transition (OCT) located between the edge of the continental and
unequivocal oceanic crusts is an ideal laboratory to understand one of the most fundamental …

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 …

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 …

Molecular hydrogen (H2) released during serpentinization of mantle rocks is one of the main
fuels for chemosynthetic life. Processes of H2 production at slow-spreading mid-ocean …

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 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 …

The tectono‐stratigraphic evolution of rift systems is at present poorly understood, especially
the one preceding the onset of oceanic seafloor spreading. Improving our understanding of …

Magmatic accretion and tectonic extension are two major ways to accommodate the plate
separation in the mid-ocean ridge (MOR). The M number, the proportion of magmatic …
