Geodynamics of oceanic plateau and plume head accretion and their role in Phanerozoic orogenic systems of China [PDF]
We present three 3D numerical models of deep subduction where buoyant material from an oceanic plateau and a plume interact with the overriding plate to assess the influence on subduction dynamics, trench geometry, and mechanisms for plateau accretion ...

Initial opening of the Eurasian Basin, Arctic Ocean
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 ...

Regional Geophysics of the Caribbean and Northern South America: Implications for Tectonics
The Caribbean plate is an enclosed oceanic basin whose formation and evolution are controversial. In the most commonly accepted model, the Caribbean plate is mainly composed of the Caribbean Large Igneous Province (CLIP) and the buoyant characteristic of

In this paper we present and analyze spreading-parallel seismic transects that image the oceanic crust in the eastern Gulf of Aden, from the Oman to the Socotra margins, across the active Sheba mid-oceanic ridge and between the Socotra-Hadbeen and ...

Volcanology and geochemistry of the Cretaceous volcaniclastic deposits and basalts from Ori Massif, Shatsky Rise Oceanic Plateau [PDF]
This study enhanced our understanding of the origin and evolution of Ori Massif, Shatsky Rise Oceanic Plateau. Key findings are: 1. Volcaniclastic deposits were formed by Surtseyan style phreatomagmatic activity, suggesting that the summit of Ori Massif ...

The closure of a subduction zone with continental terrane collision and accretion is generally thought to be followed by the initiation of a new subduction zone in the neighboring oceanic plate, which is suggested to happen repeatedly during the ...

Trophodynamics of Southern Ocean pteropods on the southern Kerguelen Plateau [PDF]
AbstractPteropods are a group of small marine gastropods that are highly sensitive to multiple stressors associated with climate change. Their trophic ecology is not well studied, with most research having focused primarily on the effects of ocean acidification on their fragile, aragonite shells.

Geochemistry and petrogenesis of Cretaceous oceanic plateau lavas in eastern Jamaica [PDF]
Basaltic lavas of Turonian to Coniacian age belonging to the Bath-Dunrobin Formation occur with intercalated island arc tuffs in the south of the Blue Mountain inlier, have been interpreted as being derived from the Caribbean oceanic plateau.

Mantle plume and rift-related volcanism during the evolution of the Rio Grande Rise
The oceanic plateau of the Rio Grande Rise, South Atlantic, was formed by mantle plume- and rift-related volcanism and shows no evidence of a continental crustal component, according to petrological and geochemical analyses of dredged volcanic rocks.
