Along ultraslow-spreading ridges, where oceanic tectonic plates drift very slowly apart,
conductive cooling is thought to limit mantle melting and melt production has been inferred …

Mid-ocean ridge basalts (MORB) provide fundamental information about the composition
and melting processes in the Earth's upper mantle. To use MORB to further our …

The formation of abyssal serpentinites leads to deep changes of the oceanic lithosphere
rheology and geochemistry, hence playing a key role on geodynamic and geochemical …

Beneath ultraslow‐spreading ridges, the oceanic lithosphere remains poorly understood.
Using recordings from a temporary array of ocean bottom seismometers, we here report an …

Very accurate timing of seismic recordings is critical for modern processing techniques.
Clock synchronization among the instruments constituting an array is, however, difficult …

Melt supply at slow‐ultraslow spreading ridges is overall reduced and highly variable.
Magma cooling and crystallization substantially shape the axial thermal regime by providing …

We estimate the seismic structure of the slow spreading Lucky Strike segment of the Mid‐
Atlantic Ridge, located approximately 300 km south of the Azores platform, using seismic …

Basalts from the Mid‐Atlantic Ridge change progressively in composition with increasing
distance from the Azores platform. Study of the Lucky Strike and Menez Gwen segments …

Drilling during ODP Leg 210 penetrated two post-rift sills (dated as∼ 105.3 and∼ 97.8 Ma)
in the deep sediments overlying basement of the continent–ocean transition zone on the …

Oxide gabbros are a minor but diffuse component of the lower oceanic crust. Their presence
poses questions on lower crust exhumation processes and magma differentiation at mid …
