Regional Geophysics of the Caribbean and Northern South America: Implications for Tectonics
Geochemistry, Geophysics, Geosystems, 2022 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

Frontiers in Earth Science, 2021 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 ...

Mantle plume and rift-related volcanism during the evolution of the Rio Grande Rise
Communications Earth & Environment, 2022 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.

Trophodynamics of Southern Ocean pteropods on the southern Kerguelen Plateau [PDF]
Ecology and Evolution, 2019 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.

Volcanology and geochemistry of the Cretaceous volcaniclastic deposits and basalts from Ori Massif, Shatsky Rise Oceanic Plateau [PDF]
, 2017 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 ...

Oceanic plateau of the Hawaiian mantle plume head subducted to the uppermost lower mantle [PDF]
, 2020 The Hawaiian-Emperor seamount chain that includes the Hawaiian volcanoes was created by the Hawaiian mantle plume. Although the mantle plume hypothesis predicts an oceanic plateau produced by massive decompression melting during the initiation stage of ...

Geochemistry, Geophysics, Geosystems, 2022 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 ...

Geodynamics of oceanic plateau and plume head accretion and their role in Phanerozoic orogenic systems of China [PDF]
, 2015 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 ...
