Thick-Skinned and Thin-Skinned Tectonics: A Global Perspective

open access: yesGeosciences, 2017
This paper gives an overview of the large-scale tectonic styles encountered in orogens worldwide. Thin-skinned and thick-skinned tectonics represent two end member styles recognized in mountain ranges.

Multiple Slabs and Complex Mantle Flows in the Molucca Sea Subduction Zone

open access: yesGeochemistry, Geophysics, Geosystems
The Molucca Sea subduction zone is unique for its active divergent double‐subducted slab located in the north of the Java and Banda subduction zones. The spatial proximity of these subduction zones would cause a complex mantle flow field.

Petrochemical characteristics of late Paleozoic magmatic rocks of the Mandakh area, southeast Mongolia

open access: yesMongolian Geoscientist, 2018
The late Paleozoic magmatic rocks are widely distributed in the Mandakh area which is located in the Gurvansaikhan and Manlai terrains, where porphyry Cu deposits occur.

Seamount Subduction and Earthquakes [PDF]

open access: yesOceanography, 2010
Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the ...

Temporal Control of Subduction Magmatism in the Eastern Trans-Mexican Volcanic Belt: Mantle Sources, Slab Contributions, and Crustal Contamination

open access: yes, 2003
The magmatic record of the easternmost part of the Trans-Mexican Volcanic Belt elucidates how temporal changes in subduction parameters influence convergent margin volcanism. In the Palma Sola massif, three phases of magmatic rocks with distinct chemical

Subduction Initiation at the Corner of Small Oceanic Basins

open access: yesGeophysical Research Letters
In Southeast Asia, emerging subduction zones often appear to begin at the corners of small oceanic basins, which have a triangular‐indenter continent–ocean boundary geometry.

Tomographic image of the crust and uppermost mantle of the Ionian and Aegean regions

open access: yesAnnals of Geophysics, 1997
We present a tomographic view of the crust and uppermost mantle beneath the Central Mediterranean area obtained from P-wave arrival times of regional earthquakes selected from the ISC bulletin.

Plume‐Driven Subduction Termination in 3‐D Mantle Convection Models

open access: yesGeochemistry, Geophysics, Geosystems
The effect of mantle plumes is secondary to that of subducting slabs for modern plate tectonics when considering plate driving forces. However, the impact of plumes on tectonics and planetary surface evolution may nonetheless have been significant.

Upper plate deformation and trench retreat modulated by subduction-driven shallow asthenospheric flows

open access: yes, 2020
International audienceUpper plate deformation within a subduction zone depends on the complex relationship between surface plate motions, trench motion, slab pull and asthenospheric flow. Previous modelling studies suggest that trench motion rates should
