Global influence of mantle temperature and plate thickness on intraplate volcanism [PDF]
Nature Communications, 2021 Here, the authors compile a global geochemical database of Neogene-Quaternary intraplate volcanism. By comparing the distribution and composition of these rocks with tomographic models they show that intraplate volcanism can be used to constrain upper ...

The return of stagnant slab recorded by intraplate volcanism. [PDF]
Proc Natl Acad Sci U S ASubducted plates often stagnate in the mantle transition zone (MTZ), and the fate of the stagnant slabs is still debatable. They may sink into the lower mantle, or remain partially trapped in the MTZ, but it is uncertain whether they can return to the upper mantle.

Linking Intraplate Volcanism to Lithospheric Structure and Asthenospheric Flow
Geochemistry, Geophysics, Geosystems, 2021 Several of Earth's intraplate volcanic provinces are hard to reconcile with the mantle plume hypothesis. Instead, they exhibit characteristics that are more compatible with shallower processes that involve the interplay between uppermost mantle flow and ...

Temporal and geochemical evolution of the Cenozoic intraplate volcanism of Zealandia [PDF]
Earth-Science Reviews, 2010 Abstract In order to constrain better the distribution, age, geochemistry and origin of widespread Cenozoic intraplate volcanism on Zealandia, the New Zealand micro-continent, we report new 40Ar/39Ar and geochemical (major and trace element and Sr–Nd–Hf–Pb isotope) data from offshore (Chatham Rise, Campbell and Challenger Plateaus) and onland (North,

Pacific plate slab pull and intraplate deformation in the early Cenozoic [PDF]
Solid Earth, 2014 Large tectonic plates are known to be susceptible to internal deformation, leading to a~range of phenomena including intraplate volcanism. However, the space and time dependence of intraplate deformation and its relationship with changing plate ...

Local slab penetration into lower mantle controls deep-focus seismicity and Changbaishan volcanism in northeast China [PDF]
Nature CommunicationsIntraplate volcanism in the Changbaishan region of northeast China is underlain by a deep subduction-related earthquake cluster in the mantle transition zone, but the underlying physical connections between them remain elusive.

Geochemistry, Geophysics, GeosystemsUpwelling and decompression of mantle plumes is the primary mechanism for large volumes of intraplate volcanism; however, many seamounts do not correlate spatially, temporally, or geochemically with plumes.

Buoyant decompression melting: A possible mechanism for intraplate volcanism [PDF]
Journal of Geophysical Research, 2002 Volcanic activity away from plate boundaries occurs in a variety of settings. Linear, age‐progressive volcanic chains have been explained as the manifestation of fixed hot spots, possibly generated by plumes originating deep in the mantle. However, important examples of oceanic intraplate volcanism cannot be explained in this way, including short‐lived
