Dynamics of intraoceanic subduction initiation: 1. Oceanic detachment fault inversion and the formation of supra‐subduction zone ophiolites
Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction
zones can form along transform faults and fracture zones, but how subduction nucleates …

Recycled arc mantle recovered from the Mid-Atlantic Ridge
Plate tectonics and mantle dynamics necessitate mantle recycling throughout Earth's history,
yet direct geochemical evidence for mantle reprocessing remains elusive. Here we present …

Mantle rock exposures at oceanic core complexes along mid-ocean ridges
The mantle is the most voluminous part of the Earth. However, mantle petrologists usually
have to rely on indirect geophysical methods or on material found ex situ. In this review …
