Central Afar: An analogue for oceanic plateau development [PDF]

Geology
Abstract The structure, composition, and evolution of oceanic plateaus are poorly understood and strongly debated. Here, we compared the magmatic history and crustal structure of Afar with the Greenland–Iceland–Faroe Ridge and other oceanic plateaus. Key similarities indicate that Central Afar represents the early stage of development of

Subduction of the oceanic Hikurangi Plateau and its impact on the Kermadec arc [PDF]

Nature Communications, 2014
Large igneous province subduction is a rare process on Earth. A modern example is the subduction of the oceanic Hikurangi Plateau beneath the southern Kermadec arc, offshore New Zealand. This segment of the arc has the largest total lava volume erupted and the highest volcano density of the entire Kermadec arc.

Bathymetry of Valdivia Bank, Walvis Ridge, South Atlantic Ocean: Implications for Structure and Geologic History of a Hot Spot Plateau

Geochemistry, Geophysics, Geosystems, 2022
Valdivia Bank is an oceanic plateau in the South Atlantic formed by hot spot magmatism at the Mid‐Atlantic Ridge during the Late Cretaceous. It is part of the Walvis Ridge, an aseismic ridge and seamount chain widely considered to be formed by age ...

Constraints on the structure of the oceanic crust of the Tamu Massif by teleseismic P-wave coda autocorrelation

Frontiers in Earth Science, 2023
The Tamu Massif, considered the biggest single volcano on Earth, was formed by the accumulation of enormous amounts of magma erupting to the surface. It is the largest and oldest seamount in Shatsky Rise, which is the third largest oceanic plateau on ...

Effects of Ocean Tide Load on Vertical Crustal Deformation in Northeastern Margin of Qinghai Tibet Plateau [PDF]

E3S Web of Conferences, 2020
Periodic crustal movement are mainly caused by ocean tides and changes of atmospheric pressure. In this project, the researcher has used the spherical harmonic coefficient of the ocean tide and actual observation data to study the impact on vertical ...

Spatial distribution of oceanic moisture contributions to precipitation over the Tibetan Plateau [PDF]

Hydrology and Earth System Sciences, 2022
Evaporation from global oceans is an important moisture source for glaciers and headwaters of major Asian rivers in the Tibetan Plateau (TP). Although the accelerated global hydrological cycle, the altered sea–land thermal contrast and the amplified ...

Magmatic surge requires two-stage model for the Laramide orogeny

Nature Communications, 2023
The Laramide orogeny is a pivotal time in the geological development of western North America, but its driving mechanism is controversial. Most prominent models suggest this event was caused by the collision of an oceanic plateau with the Southern ...

Temperatures in ambient mantle and plumes: Constraints from basalts, picrites, and komatiites [PDF]

, 2006
Several methods have been developed to assess the thermal state of the mantle below oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of erupted lavas. One leads to the conclusion that mantle potential temperature (i.e.

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 ...
