How transform fault shear influences where detachment faults form near mid-ocean ridges [PDF]
Scientific Reports, 2023 Oceanic detachment faults represent an end-member form of seafloor creation, associated with relatively weak magmatism at slow-spreading mid-ocean ridges.

The mechanism of tidal triggering of earthquakes at mid-ocean ridges [PDF]
Nature Communications, 2019 Tidal triggering of earthquakes at Axial Volcano on the Juan de Fuca ridge is shown to be driven by tidally induced magma chamber inflation. Fitting the data to theory requires that the frictional parameter A be much smaller than laboratory measurements ...

The Mode of Trench-Parallel Subduction of the Middle Ocean Ridge
Frontiers in Earth Science, 2021 Trench-parallel subduction of mid-ocean ridges occurs frequently in plate motion history, such as along the western boundary of the Pacific plate in the early Cenozoic and along the eastern boundary of the Pacific plate at present.

Geochemistry, Geophysics, Geosystems, 2021 The Macquarie Ridge Complex (MRC) on the Australia‐Pacific plate boundary south of New Zealand is an extinct mid‐ocean ridge that has experienced a complex tectonic history and produced highly heterogeneous mid‐ocean ridge basalts (MORBs).

Ecology and Evolution, 2021 Mid‐ocean ridges generate a myriad of physical oceanographic processes that favor the supply of food and nutrients to suspension‐ and filter‐feeding organisms, such as cold‐water corals and deep‐sea sponges.

P-velocity of the upper mantle
Геофизический журнал, 2021 The authors have constructed models featuring seismic P-wave velocity distribution in the upper mantle beneath oceanic, continental and transition regions, such as mid-ocean ridges, basins, trenches, island arcs, and back-arc troughs, Atlantic ...

Do Olivine Crystallization Temperatures Faithfully Record Mantle Temperature Variability?
Geochemistry, Geophysics, Geosystems, 2021 Crystallization temperatures of primitive olivine crystals have been widely used as both a proxy for, or an intermediate step in calculating, mantle temperatures. The olivine‐spinel aluminum‐exchange thermometer has been applied to samples from mid‐ocean

Volcanic evolution of an ultraslow-spreading ridge
Nature Communications, 2023 Nearly 30% of ocean crust forms at mid-ocean ridges where the spreading rate is less than 20 mm per year. According to the seafloor spreading paradigm, oceanic crust forms along a narrow axial zone and is transported away from the rift valley.

Global Hydrogen Production During High‐Pressure Serpentinization of Subducting Slabs
Geochemistry, Geophysics, Geosystems, 2023 Serpentinization is among the most important, and ubiquitous, geological processes in crustal–upper mantle conditions (
