Slab tearing and its surface signals controlled by passive margin strength [PDF]

open access: yesNature Communications
Slab tearing, the lateral detachment of subducting oceanic slab from continental lithosphere, is widely inferred from seismic tomography, yet its surface expressions in mountain belts and adjacent foreland basins remain ambiguous and often contradictory.

Volcanism in slab tear faults is larger than in island-arcs and back-arcs [PDF]

open access: yesNature Communications, 2017
The volcanism of subduction settings concentrates in island-arcs and back-arc basins. Here, the authors show that the lithospheric tear faults bounding roll-backing slabs may focus huge volcanism with a volume of the erupted products exceeding that of ...

Transient Injection of Flow: How Torn and Bent Slabs Induce Unusual Mantle Circulation Patterns Near a Flat Slab

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Torn and bent slabs are usually associated with flat‐slab subduction where the descending plate develops a horizontal geometry beneath the overlying continent.

Mantle flow through a tear in the Nazca slab inferred from shear wave splitting

open access: yesGeophysical Research Letters, 2017
A tear in the subducting Nazca slab is located between the end of the Pampean flat slab and normally subducting oceanic lithosphere. Tomographic studies suggest mantle material flows through this opening.

Insights from the P Wave Travel Time Tomography in the Upper Mantle Beneath the Central Philippines

open access: yesRemote Sensing, 2021
In this paper, we present a high resolution 3-D tomographic model of the upper mantle obtained from a large number of teleseismic travel time data from the ISC in the central Philippines.

Slab Tearing Underneath the Bransfield Strait, Antarctica

open access: yesGeophysical Research Letters, 2023
We conduct a P‐wave receiver function analysis of the Bransfield Strait (West Antarctica) to determine the lithospheric structure of this back‐arc basin, thanks to 31 temporary and permanent stations. Our main finding is a 15 km tear of the Phoenix slab,

Deep subduction of the Philippine Sea slab and formation of slab window beneath central Japan

open access: yesEarth, Planets and Space, 2023
The geometry of the Philippine Sea slab (PHS) subducting beneath the Japanese islands has been imaged to 400 km depth beneath the Kyushu and Chugoku regions, whereas the PHS slab geometry beneath the Hokuriku region has only been determined to ~ 140 km ...

Transfer zones in Mediterranean back-arc regions and tear faults

open access: yesBSGF - Earth Sciences Bulletin, 2021
Slab tearing induces localized deformations in the overriding plates of subduction zones and transfer zones accommodating differential retreat in back-arc regions.

Seismic anisotropy across Adria plate, from the Apennines to the Dinarides

open access: yesFrontiers in Earth Science, 2022
The Adria microplate has the particular feature to be involved in two subduction systems with slab dipping in opposite directions, one toward west beneath the Apennines and the other to the east beneath the Dinarides.

The dynamics of laterally variable subductions: laboratory models applied to the Hellenides [PDF]

open access: yesSolid Earth, 2013
We designed three-dimensional dynamically self-consistent laboratory models of subduction to analyse the relationships between overriding plate deformation and subduction dynamics in the upper mantle.
