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

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.

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 ...

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.

Control of Subduction Zone Age and Size on Flat Slab Subduction
Frontiers in Earth Science, 2020 Flat slab subduction is an enigmatic style of subduction where the slab attains a horizontal orientation for up to several hundred kilometers below the base of the overriding plate.

TerraceM-2: A Matlab® Interface for Mapping and Modeling Marine and Lacustrine Terraces
Frontiers in Earth Science, 2019 The morphology of marine and lacustrine terraces has been largely used to measure past sea- and lake-level positions and estimate vertical deformation in a wealth of studies focused on climate and tectonic processes.

The link between great earthquakes and the subduction of oceanic fracture zones [PDF]
Solid Earth, 2012 Giant subduction earthquakes are known to occur in areas not previously identified as prone to high seismic risk. This highlights the need to better identify subduction zone segments potentially dominated by relatively long (up to 1000 yr and more ...
