A review of the seismotectonics of the Makran Subduction Zone as a baseline for Tsunami Hazard Assessments

Geoscience Letters, 2019
The Makran Accretionary Wedge (900 km across) is a consequence of northward subduction of the oceanic part of the Arabian Plate beneath the Lut and Afghan blocks in the northwestern Indian Ocean.

Response of the mantle to flat slab evolution: Insights from local splitting beneath Peru [PDF]

, 2014
The dynamics of flat subduction, particularly the interaction between a flat slab and the overriding plate, are poorly understood. Here we study the (seismically) anisotropic properties and deformational regime of the mantle directly above the Peruvian ...

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems
Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt.

Targeting deeply-sourced seeps along the Central Volcanic Zone [version 1; peer review: 2 approved, 1 approved with reservations]

Open Research Europe
At convergent margins, plates collide producing a subduction process. When an oceanic plate collides with a continental plate, the denser (i.e., oceanic) plate subducts beneath the less dense (continental) plate.

Metallogeny of subduction zones

Vestnik MGTU, 2017
The paper deals with the multistage mechanism of the Earth's crust enrichment in ore elements in underthrust zones. The processes of metamorphism and the formation of hydrothermal solutions at pulling of the watered oceanic lithospheric plate into the subduction zone have been described.

Deeply subducted continental fragments - Part 2: Insight from petrochronology in the central Sesia Zone (western Italian Alps) [PDF]

, 2018
Subducted continental terranes commonly comprise an assembly of subunits that reflect the different tectono-metamorphic histories they experienced in the subduction zone.

Modeling pN2 through Geological Time: Implications for Planetary Climates and Atmospheric Biosignatures [PDF]

, 2016
Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this ...

Subduction Zone Magmas

, 2013
The importance of subduction zones, which are major sites of earthquakes, mountain building, and basalt–andesite–rhyolite volcanism, was nicely presented by Stern (Rev Geophys 40:1012, 2002): “Subduction zones are also our planet’s largest recycling system.

Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes [PDF]

, 2007
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996 M_w 7.7 and 23 June 2001 M_w 8.5 southern Peru subduction zone earthquakes, as well as two large aftershocks following the 2001 earthquake ...

Earthquake Relocation Using Double Difference Method for 2D Modelling of Subducting Slab and Back Arc Thrust in West Nusa Tenggara

Jurnal Penelitian Fisika dan Aplikasinya, 2018
West Nusa Tenggara is classified into earthquake prone zone as it is located between subduction and back arc thrust earthquake sources. Accurate hypocenter determination in this area is necessary for strong motion calculation and earthquake source zone ...
