Oceanic detachment faults generate compression in extension (2017)
Journal Article

Geology, 45(10), 923-926. https://doi.org/10.1130/g39232.1In extensional geologic systems such as mid-ocean ridges, deformation is typically accommodated by slip on normal faults, where material is pulled apart under tension and stress is released by rupture during earthquakes and magmatic accretion. Howeve... Read More about Oceanic detachment faults generate compression in extension.

Geophysical Journal International, 210(3), 1681-1702. https://doi.org/10.1093/gji/ggx260Subducting bathymetric anomalies enhance erosion of the overriding forearc crust. The deformation associated with this process is superimposed on pre-existing variable crustal and sedimentary structures developed as a subduction system evolves. Recen...
