Late paleozoic to early mesozoic provenance record of paleo-pacific subduction beneath South China [PDF]

open access: yes, 2015
Northeast trending Yong'an Basin, southeast South China Craton, preserves a Permian-Jurassic, marine to continental, siliciclastic-dominated, retroarc foreland basin succession.

Stress heterogeneities in exhumed high-pressure rocks shed light on deep subduction interface transient coupling

open access: yesNature Communications
Stress distribution and creep mechanisms along modern subduction interfaces remain poorly understood, due to the lack of high-resolution constraints on the rheology of the heterogeneous plate interface and associated fluid distribution in the so-called ...

Orphaning Regimes: The Missing Link Between Flattened and Penetrating Slab Morphologies

open access: yesFrontiers in Earth Science, 2020
Slab orphaning is a newly discovered phenomenological behavior, where the slab tip breaks off at the top of the lower mantle (~660 km depth) and is abandoned by its parent slab.

Seismic visibility of a deep subduction channel – insights from numerical simulation of high-frequency seismic waves emitted from intermediate depth earthquakes [PDF]

open access: yesSolid Earth, 2014
Return flow in a deep subduction channel (DSC) has been proposed to explain rapid exhumation of high pressure–low temperature metamorphic rocks, entirely based on the fossil rock record.

Anomalous Sediment Consolidation and Alteration From Buried Incoming Plate Seamounts Along the Cascadia Margin

open access: yesGeochemistry, Geophysics, Geosystems
Oceanic plate seamounts are believed to play an important role in megathrust rupture at subduction zones, although consistent relationships between subducting seamounts and plate interface seismicity patterns are not found.

Objective detection of long-term slow slip events along the Nankai Trough using GNSS data (1996–2016)

open access: yesEarth, Planets and Space, 2017
This paper presents a method for objective detection of long-term slow slip events with durations on the order of years, on the plate boundary along the Nankai Trough, relying on global navigation satellite system daily coordinate data.

Generation of normal and adakite-like calc-alkaline magmas in a non-subductional environment: An Sr-O-H isotopic study of the Apuseni Mountains neogene magmatic province, Romania [PDF]

open access: yes, 2007
Neogene magmatism in the Apuseni Mountains of Romania was active between 15 and 7 Ma, with an isolated final eruption at 1.6 Ma. Several groups of magmatic rocks can be distinguished in the province on the basis of ages, trace elements and isotopic ...

Long-term slow slip events along the Nankai trough subduction zone after the 2011 Tohoku earthquake in Japan

open access: yesEarth, Planets and Space, 2017
The global navigation satellite system (GNSS) network in Japan has detected transient crustal deformation in regions along the Nankai trough subduction zone in southwest Japan from approximately 2013, after the 2011 Tohoku earthquake. Using the GNSS data,

Mesoscale subduction at the Almeria-Oran front. Part 1: ageostrophic flow [PDF]

open access: yes, 2001
This paper presents a detailed diagnostic analysis of hydrographic and current meter data from three, rapidly repeated, fine-scale surveys of the Almeria-Oran front.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
