Controls on volcanism at intraplate basaltic volcanic fields

Earth and Planetary Science Letters, 2017
A broad range of controlling mechanisms is described for intraplate basaltic volcanic fields (IBVFs) in the literature. These correspond with those relating to shallow tectonic processes and to deep mantle plumes. Accurate measurement of the physical parameters of intraplate volcanism is fundamental to gain an understanding of the controlling factors ...

The Dunedin Volcanic Group and a revised model for Zealandia's alkaline intraplate volcanism

New Zealand Journal of Geology, and Geophysics, 2020
ABSTRACT The intraplate rocks of the Dunedin Volcanic Group (DVG) in New Zealand's South Island erupted in two discrete areas between 25 and 21 Ma before becoming distributed over > 7,800 km 2 until ∼9 Ma.

Recycling of oceanic crust and the origin of intraplate volcanism

Australian Journal of Earth Sciences, 2013
Source models for intraplate volcanism (IPV) include vertical introduction of material from deep in the mantle (plume model), contamination of the shallow mantle (perisphere and continental mantle delamination models) and derivation by selective partial melting of oceanic crust recycled into the depleted mantle (SUMA/streaky mantle models).

B″ not D″ as the source of intraplate volcanism

2022
ABSTRACT Under fast-moving oceanic plates, the asthenosphere seismic B″ region becomes isolated from the convecting mantle by plate drag and acts as an advecting layer, which can serve as a long-lived source for intraplate volcanism.

Late Cenozoic intraplate volcanism in Changbai volcanic field, on the border of China and North Korea: insights into deep subduction of the Pacific slab and intraplate volcanism

Journal of the Geological Society, 2014
Late Cenozoic intraplate volcanism in the Changbai volcanic field straddles the border between China and North Korea, forming basic (alkali basalts and tholeiites) and intermediate–acidic (trachytes and peralkaline rhyolites) volcanic rocks with ages ranging from 19.9 Ma to the present.

Numerical modeling of the formation of extensive intraplate volcanism

2023
The occurrence of mantle melting is generally attributed to high temperature, decreased pressure, and/or the presence of volatiles such as water. Volcanism away from plate boundaries is ascribed to intraplate or anorogenic volcanism, which may reveal important dynamics of the deep mantle.
