and tsunami will certainly continue to drive future subduction zone science. Completion of the work started via NanTroSEIZE and CRISP would help achieve goals of understanding fault zone processes. In particular, realizing the goal of borehole sampling of the deep (>2–3km)plate boundaryfault zo...
A subduction zone is a convergent tectonic boundary where one plate slides beneath another. Oceanic crust is required for one to initiate. The colder, denser plate will bend and slide beneath the other warmer and more buoyant one. What happens at a subduction zone? At subduction zones, one pl...

The Makran subduction zone (originally pronounced as “Makkoran”), in western Asia, is the convergent boundary between the Arabian oceanic plate and the southern margin of the Iranian micro-continent in SE Iran and Eurasia in the south of Pakistan. It is the only segment, in central part ...
36. Mineral assemblages constrain brecciation to a depth range of 30–80 km in the Alpine subduction zone, thus consistent with the CH4formation conditions. We suggest that the migration and accumulation of CH4-H2-rich fluids below a permeability seal, possibly promoted by CH4and H2...
The definition of subduction is the process that occurs when two tectonic plates meet at convergent boundaries, and one of the plates moves under the other one due to gravity and differences in density. The boundary area where this occurs is the subduction zone. In the image below, an ...
We test the role of the advance rate (indentation rate) of the India–Eurasia convergent boundary, i.e. the Indian continental subduction zone hinge and slab (vI), relative to the rollback rate of the Western Pacific (vWP) and Sunda (vSu) subduction zones on the style and extent of cont...
In some sections, it shows unconformable relation with the overlying cu- mulate ultramafic rocks signifying the physical existence of crust- mantle boundary (~petrological Moho). Exposures of cumulate peridotites and gabbros have been encoun- tered to the northeast of Moki, north of Washelo, The...
Subduction zones have recurrently formed on Earth. Previous studies have, however, suggested that they are unlikely to start in the interior of a pristine ocean. Instead, they seem to be more likely to form from another pre-existing subduction zone. One
