Lithosphere Structure of the Southern Dinarides and Continuity of the Adriatic Lithosphere Slab Beneath the Northern Dinarides Unravelled by Seismic Modelling

open access: yesGeosciences, 2022
Currently recognised lithospheric models hypothesise the non-existence of a lithospheric slab (a so-called slab gap) in the area of the Northern Dinarides, and the possible existence of a shallow slab in the Southern Dinarides.

Kinematics of subduction and subduction‐induced flow in the upper mantle [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2004
Results of fluid dynamical experiments are presented to model the kinematics of lithospheric subduction in the upper mantle. The experiments model a dense high‐viscosity plate (subducting lithosphere) overlying a less dense low‐viscosity layer (upper mantle). The overriding lithosphere is not incorporated.

On the initiation of subduction zones

open access: yespure and applied geophysics, 1989
Analysis of the relation between intraplate stress fields and lithospheric rheology leads to greater insight into the role that initiation of subduction plays in the tectonic evolution of the lithosphere. Numerical model studies show that if after a short evolution of a passive margin (time span a few tens of million years) subduction has not yet ...

Effect of a weak layer at the lithosphere-asthenosphere boundary on subduction dynamics [PDF]

open access: yes, 2022
The aim of this thesis is to investigate and identify the first order effects of a weak layer at the lithosphere asthenosphere boundary (LAB) on a subduction zone, as to date, no previous geodynamics studies on this topic exist.

Back to full interseismic plate locking decades after the giant 1960 Chile earthquake

open access: yesNature Communications, 2018
Great megathrust earthquakes arise from the sudden release of strain accumulated during centuries of interseismic plate convergence. Here, the authors reconstruct interseismic strain accumulation since the 1960 Chile earthquake, finding a transient ...

The Impact of the Caroline Ridge Subduction on the Geomorphological Characteristics of Major Landforms in the Yap Subduction Zone

open access: yesJournal of Marine Science and Engineering, 2022
The Caroline Ridge (CR) subduction underneath the Philippine Sea Plate brings complex morphotectonic characteristics to the Yap Subduction Zone (YSZ) compared to other normal intra-oceanic subduction systems.

The secret to starting subduction is ... subduction

open access: yes, 2020
Caroline Eakin, ANU The Earth's biggest earthquakes and most explosive volcanoes occur at subduction zones" where a tectonic plate (the seafloor itself) sinks bank into the Earth's interior. We've been able to compile 100 million years of existing evidence for Subduction Zone Initiation (SZI).

Subducting slabs: Jellyfishes in the Earth's mantle [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2010
The constantly improving resolution of geophysical data, seismic tomography and seismicity in particular, shows that the lithosphere does not subduct as a slab of uniform thickness but is rather thinned in the upper mantle and thickened around the transition zone between the upper and lower mantle. This observation has traditionally been interpreted as

PALEOZOIC GRANITOID MAGMATISM OF THE URALS: THE REFLECTION OF THE STAGES OF THE GEODYNAMIC AND GEOCHEMICAL EVOLUTION OF A COLLISIONAL OROGEN

open access: yesГеодинамика и тектонофизика, 2021
The Ural mobile belt is an intracontinental epioceanic orogen that has already gone through all stages of the geodynamic development. Igneous rocks formed during each stage are important indicators for understanding the evolution of this belt and ...

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 ...
