Subduction Initiation and Mafic Intrusions: Rethinking the South China Sea-Luzon Connection

open access: yesCT Lilun yu yingyong yanjiu
The conventional view suggests that the subduction of the South China Sea plate beneath Luzon occurred due to the oceanic lithosphere’s high density, facilitating subduction initiation.

Initial opening of the Eurasian Basin, Arctic Ocean

open access: yesFrontiers in Earth Science, 2016
Analysis of the transition from the NE Yermak Plateau into the oceanic Eurasian Basin sheds light on the Paleocene formation of this Arctic basin. Newly acquired multichannel seismic data with a 3600 m long streamer shot during ice-free conditions ...

Provenance history of a Late Triassic-Jurassic Gondwana margin forearc basin, Murihiku Terrane, North Island, New Zealand: petrographic and geochemical constraints [PDF]

open access: yes, 2004
The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with ...

EXPLOITATION OF THE CONTINENTAL SHELF IN DISPUTED AREAS AN EXAMPLE OF THE ARCTIC OCEAN

open access: yesBRICS Law Journal, 2016
This paper aims to examine the legal regime related to define the outer limits of the continental shelf beyond 200 NM. Firstly, special focus will be on the development of the legal concept of the continental shelf.

Mechanical decoupling of high-pressure crustal units during continental subduction. [PDF]

open access: yes, 2008
International audienceThe mechanics of the transition from continental subduction toward upper crustal nappe stacking is still poorly understood and is studied here through a 2D thermal and strength numerical modelling of a subducted passive margin ...

Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane [PDF]

open access: yes, 2015
The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand collision process is a Middle?

The Late Triassic-Early Jurassic active continental margin of western North America in northeastern Mexico [PDF]

open access: yesGeofísica Internacional, 1998
Exposures of Triassic-Jurassic volcanic sequences in northeastern Mexico suggest that they developed along an active continental margin. Other sequences in support of such a tectonic environment are exposed in Durango, Zacatecas, San Luis Potosí, Nuevo ...

Coupling Between Exhumation and Subduction: A Case Study From the Southern Great Xing'an Range, NE Asia

open access: yesGeophysical Research Letters, 2023
The link between subduction and continental exhumation is explored using high‐resolution thermal histories from southern Great Xing'an Range (GXR), NE Asia and integrated with a regional low‐temperature thermochronology data synthesis from the NE Asian ...
