Stagnant slab: a review

Y Fukao, M Obayashi, T Nakakuki… - Annual Review of …, 2009 - annualreviews.org
A stagnant slab is a subducted slab of oceanic lithosphere subhorizontally deflected above,

Modeling the dynamics of subducting slabs

MI Billen - Annu. Rev. Earth Planet. Sci., 2008 - annualreviews.org
Cold, dense subducting lithosphere provides the primary force driving tectonic plates at
Earth's surface. The force available to drive the plates depends on a balance between the …

A benchmark comparison of spontaneous subduction models—Towards a free surface

H Schmeling, AY Babeyko, A Enns, C Faccenna… - Physics of the Earth and …, 2008 - Elsevier
Numerically modelling the dynamics of a self-consistently subducting lithosphere is a
challenging task because of the decoupling problems of the slab from the free surface. We …

Subduction-triggered magmatic pulses: A new class of plumes?

C Faccenna, TW Becker, S Lallemand… - Earth and Planetary …, 2010 - Elsevier
A variety of atypical plume-like structures and focused upwellings that are not rooted in the
lower mantle have recently been discussed, and seismological imaging has shown …

Influence of trench width on subduction hinge retreat rates in 3‐D models of slab rollback

DR Stegman, J Freeman, WP Schellart… - Geochemistry …, 2006 - Wiley Online Library
Subduction of tectonic plates limited in lateral extent and with a free‐trailing tail, ie,“free
subduction,” is modeled in a three‐dimensional (3‐D) geometry. The models use a …

Mechanisms and implications of deep earthquakes

Z Zhan - Annual Review of Earth and Planetary Sciences, 2020 - annualreviews.org
Deep earthquakes behave like shallow earthquakes but must have fundamentally different
physical processes. Their rupture behaviors, magnitude-frequency statistics, and aftershocks …

Why did Arabia separate from Africa? Insights from 3-D laboratory experiments

N Bellahsen, C Faccenna, F Funiciello… - Earth and Planetary …, 2003 - Elsevier
We have performed 3-D scaled lithospheric experiments to investigate the role of the
gravitational force exerted by a subducting slab on the deformation of the subducting plate …

Rheologic controls on slab dynamics

MI Billen, G Hirth - Geochemistry, Geophysics, Geosystems, 2007 - Wiley Online Library
Several models have been proposed to relate slab geometry to parameters such as plate
velocity or plate age. However, studies on the observed relationships between slab …

Map** mantle flow during retreating subduction: Laboratory models analyzed by feature tracking

F Funiciello, M Moroni, C Piromallo… - Journal of …, 2006 - Wiley Online Library
Three‐dimensional dynamically consistent laboratory models are carried out to model the
large‐scale mantle circulation induced by subduction of a laterally migrating slab. A …

Depressed 660-km discontinuity caused by akimotoite–bridgmanite transition

A Chanyshev, T Ishii, D Bondar, S Bhat, EJ Kim… - Nature, 2022 - nature.com
The 660-kilometre seismic discontinuity is the boundary between the Earth's lower mantle
and transition zone and is commonly interpreted as being due to the dissociation of …
