Subduction of oceanic lithosphere in the Alps: Selective and archetypal from (slow-spreading) oceans
, 2021 The Alps are amongst the best subduction archives in the world, with abundant blueschists and eclogites preserving fragments of mantle, gabbros, thinned continental margin and pelagic sediments partly within their pre-collisional architecture.

Earth and Space Science, 2022 On 24 March 2021, an Mw 5.3 earthquake struck northwest Baicheng, located in the Kuqa fold‐and‐thrust belt (FTB), northwest China. In the current study, interferometric synthetic aperture radar (InSAR) data were used to investigate the associated fault ...

A role for subducted albite in the water cycle and alkalinity of subduction fluids [PDF]
Nature Communications, 2021 AbstractAlbite is one of the major constituents in the crust. We report here that albite, when subjected to hydrous cold subduction conditions, undergoes hitherto unknown breakdown into hydrated smectite, moganite, and corundum, above 2.9 GPa and 290 °C or about 90 km depth conditions, followed by subsequent breakdown of smectite into jadeite above 4.3

Frontiers in Earth Science, 2022 Post-subduction dextral faulting was restored to evaluate the spatial distribution of units of the Franciscan subduction complex of California that formed as a result of subduction accretion. The Franciscan and related rocks of western California exhibit

Slab2, a comprehensive subduction zone geometry model
Science, 2018 Detailing subduction zones Subduction zones are responsible for the most-damaging and tsunami-generating great earthquakes. Hayes et al. updated their Slab1.0 model to include all seismically active subduction zones, including geometrically complex ...

Evolution of Subduction Cusps From the Perspective of Trench Migration and Slab Morphology
Frontiers in Earth Science, 2021 The geometries of trenches vary worldwide due to continuous plate boundary reorganization. When two trenches intersect to generate a corner, a subduction cusp is formed.

Properties of the Subduction System in Mexico [PDF]
, 2011 This thesis presents seismic imaging results of the structure of the Mexican subduction zone using receiver function (RF) based on teleseismic P-to-S converted waves, in order to gain insight into the physical and chemical factors associated with ...

Nature, 2019 A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth’s history. Here we discuss the processes that move carbon towards subduction zones and transform it into fluids, magmas, volcanic gases and diamonds.

(I) A Coupled Geochemical and Geodynamical Approach to Subduction Zone Modeling and (II) Development of Color in Greenish Quartz [PDF]
, 2008 (I) We couple a petrological model with a 2D thermal and variable viscosity flow model to describe and compare fundamental processes occurring within subduction zones.

Geoscience Frontiers, 2019 Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity. However, crustal signatures in the mantle source of basaltic rocks above subduction zones were primarily incorporated in the form of liquid rather than solid phases ...
