Mantle upwelling induced by slab rollover subduction could explain widespread intraplate volcanism in Tibet

open access: yesCommunications Earth & Environment
Subduction-induced mantle flow has a considerable geodynamic impact on Earth. It can deflect mantle plumes, transport geochemical signatures and produce upwellings that generate atypical intraplate volcanism.

Spotlight 7: Graveyard Seamounts [PDF]

open access: yesOceanography, 2010
The “Graveyard seamounts” comprise a complex of 28 small volcanic edifices covering about 140 km2 on the northern flank of the Chatham Rise, an oceanic plateau that extends several hundred kilometers east of New Zealand.

Hydrous Regions of the Mantle Transition Zone Lie Beneath Areas of Continental Intraplate Volcanism

open access: yesGeochemistry, Geophysics, Geosystems
Great volumes of water are carried downward into the mantle transition zone (MTZ, 410–670 km depth) by subducting slabs. If this water is later drawn upward, the resulting mantle melting may generate continental intraplate volcanism (IPV).

Melt inclusions reveal massive carbon dioxide emissions from continental intraplate volcanism

open access: yesCommunications Earth & Environment
The quantities of carbon dioxide (CO2) carried by magmas affect the style of volcanic eruptions and the evolution of Earth’s climate over geological time.

Basaltic Explosive Volcanism in a tuff-dominated Intraplate Setting, Sarmiento Formation (Middle Eocene- lower Miocene), Patagonia Argentina

open access: yesLatin American Journal of Sedimentology and Basin Analysis
The Sarmiento Formation (middle Eocene to early Miocene) represents the distal record of the activity of the Andean volcanic arc in central Patagonia, mainly dominated by accumulation and reworking of fine ash in a low-gradient continental setting ...

Tomographic consistency in imaging lower-mantle plumes and their link to European Cenozoic Rift Volcanism

open access: yesEarth and Planetary Physics
A wide northeast-trending belt of intraplate alkaline volcanism, exhibiting similar geochemical characteristics, stretches from the Eastern Atlantic Ocean to the Cenozoic rift system in Europe.

A review of geophysical studies on the Mongolian Plateau

open access: yesEarthquake Science
The Mongolian Plateau in Central Asia is an intracontinental tectonic system far from active plate boundaries. Despite its distance from these boundaries, the plateau is characterized by intense crustal deformation accompanied by voluminous Cenozoic ...

Recycled Oceanic Crust in the Source of the Intraplate Changbaishan‐Tianchi Volcano, China/North Korea

open access: yesGeochemistry, Geophysics, Geosystems
Continental intraplate volcano is an ideal probe to unravel the composition and structure of the deep Earth. The intraplate Changbaishan‐Tianchi volcano was one of the most hazardous eruptions on the Earth's planet. The long‐term activity of this volcano
