Coupled magmatic and tectonic activity plays an important role in high-temperature
hydrothermal circulation at mid-ocean ridges. The circulation patterns for such systems have …

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 ridges display tectonic segmentation defined by discontinuities of the axial zone,
and geophysical and geochemical observations suggest segmentation of the underlying …

The oceanic crust is formed by a combination of magmatic and tectonic processes at mid‐
ocean spreading centers. Under ultraslow spreading environment, however, observations of …

At slow spreading ridges, axial detachment faults exhume mantle‐derived peridotites and
hydrothermal alteration causes serpentinization in a domain extending more than 1 km next …

Maximum depths of earthquakes in different settings are commonly thought to lie within a
transition, many kilometers in width, from brittle deformation at shallow depths to plastic …

Ultraslow spreading ridges form the slowest divergent plate boundaries and exhibit distinct
spreading processes in volcanically active magmatic sections and intervening amagmatic …

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

Two geophysical expeditions (LOMROG II and III) were carried out in 2009 and 2012 to
acquire seismic data in the western Amundsen Basin in the Arctic Ocean, a basin formed by …

In volcanic regions ascending magma is subject to depressurization and is generally
accompanied by exsolution of volatiles. We assume a process in which these volatiles …
