Metallogeny of subduction zones [PDF]
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 ...

Organic carbon recycling in subduction zones [PDF]
Nature CommunicationsAbiotic solid organic compounds constitute a ubiquitous byproduct of oceanic lithosphere serpentinization but their evolution and fate during subduction remains largely unexplored.

Rapid tremor migration and pore-pressure waves in subduction zones [PDF]
Nature Communications, 2018 Rapid tremor migration in subduction zones has been associated with aseismic, shear strain at the plate interface. Here, the authors develop a physical model that shows that pore-pressure waves at the plate interface are likely to generate secondary slip

Large megathrust earthquakes in cold mantle wedge corners under lawsonite blueschist facies [PDF]
Nature CommunicationsGiant megathrust earthquakes typically occur above the upper-plate Moho or the 350°C isotherm in warm subduction zones. However, large earthquakes also occur within the mantle wedge corner at 35-55 km depth at cold subduction zones, such as the Kermadec,

Marine terraces of the last interglacial period along the Pacific coast of South America (1° N–40° S) [PDF]
Earth System Science Data, 2021 Tectonically active coasts are dynamic environments characterized by the presence of multiple marine terraces formed by the combined effects of wave erosion, tectonic uplift, and sea-level oscillations at glacial-cycle timescales.

Elements, 2020 Fluids are essential to the physical and chemical processes in subduction zones. Two types of subduction-zone fluids can be distinguished. First, shallow fluids, which are relatively dilute and water rich and that have properties that vary between subduction zones depending on the local thermal regime.

Fast Holocene slip and localized strain along the Liquiñe-Ofqui strike-slip fault system, Chile
Scientific Reports, 2021 In active tectonic settings dominated by strike-slip kinematics, slip partitioning across subparallel faults is a common feature; therefore, assessing the degree of partitioning and strain localization is paramount for seismic hazard assessments.

Frontiers in Earth Science, 2021 Evaluating the transfer of stresses from megathrust earthquakes to adjacent segments is fundamental to assess seismic hazard. Here, we use a 3D forward model as well as GPS and seismic data to investigate the transient deformation and Coulomb Failure ...

Introduction to subduction zones [PDF]
pure and applied geophysics, 1988 Subduction zones present many facades to those that observe them. From obvious features to obscure yet important processes, there are many aspects of subduction zones to observe and explain. Notable examples of obvious features are volcanoes, earthquakes, mountain belts, and deep sea trenches; while on the other hand, the unseen process of sediment ...

Ocean-continent subduction cannot be initiated without preceding intra-oceanic subduction!
Frontiers in Earth Science, 2022 The formation of new subduction zones is a key element of plate tectonics and the Wilson cycle, and many different controlling mechanisms have been proposed to initiate subduction.
