Mantle Transition Zone Structure Beneath the Sunda–Java Trench and Christmas Island: Implications for Deep Dehydration and Petit-Spot Volcanism

Geosciences
Petit-spot volcanism is a type of intraplate volcanism that commonly occurs near the outer rise in subducting plates. Although deformation of the incoming plate is considered important for its development, the deeper mantle processes contributing to this

Mantle dynamics beneath the Pacific Northwest and the generation of voluminous back‐arc volcanism

Geochemistry, Geophysics, Geosystems, 2012
The Pacific Northwest (PNW) has a complex tectonic history and over the past ∼17 Ma has played host to several major episodes of intraplate volcanism.

Etnean and Hyblean volcanism shifted away from Malta Escarpment by crustal stresses

, 2018
A fraction of the volcanic activity occurs intraplate, challenging our models of melting and magma transfer to the Earth’s surface. A prominent example is Mt.

The origin of diverse intraplate volcanism in the Central and Equatorial Atlantic Ocean [PDF]

, 2019
Despite decades of research, the origin of oceanic intraplate volcanism and the location of its magma source(s) are still a matter of debate. Intraplate volcanism was originally tightly connected with the mantle plume concept (e.g.

Understanding Non-Plume Related Intraplate Volcanism

, 2016
Intraplate volcanism is a worldwide phenomenon producing volcanoes away from active plate boundaries, a process that cannot yet be sufficiently explained by plate tectonic processes, and thus is still a missing piece in the understanding of the dynamics ...

Mantle melting and intraplate volcanism due to self‐buoyant hydrous upwellings from the stagnant slab that are conveyed by small‐scale convection

, 2019
The mechanisms sustaining basaltic continental intraplate volcanism remain controversial. Continental intraplate volcanism is often geographically associated with slab stagnation in the mantle transition zone (MTZ), for example, in eastern Asia, central ...

Secondary Plumes Formation Controlled by Interaction of Thermochemical Mantle Plumes With the Mantle Transition Zone

Geophysical Research Letters
The causes and global distribution of intraplate volcanism remain poorly understood, particularly the occurrence of scattered magmatism unrelated to large igneous provinces (LIPs).

Spotlight 7: Graveyard Seamounts [PDF]

Oceanography, 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

Geochemistry, 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).
