The Atlas of Morocco: A Plume‐Assisted Orogeny

Geochemistry, Geophysics, Geosystems, 2023
We explore the connections between crustal shortening, volcanism, and mantle dynamics in the Atlas of Morocco. In response to compressional forces and strain localization, this intraplate orogen has evolved far from convergent plate margins.

A Plate‐Mantle Convection System in the West Pacific Revealed by Tertiary Ultramafic‐Mafic Volcanic Rocks in Southeast China

Earth and Space Science, 2021
Cenozoic volcanic rocks in the East Asian continental margin usually form because of asthenosphere upwelling and resultant decompression melting, and their origins are important in deciphering mantle geodynamics attributed to intraplate volcanism.

An Asthenospheric Upwelling Beneath Central Mongolia — Implications for Intraplate Surface Uplift and Volcanism

, 2021
Intraplate processes, such as continental surface uplift and intraplate volcanism, are enigmatic and the underlying mechanisms responsible are not fully understood.

Asthenospheric Flow From East Asia to the Philippine Sea Plate Revealed by Rj‐MCMC Inversion of Surface Waves

Geochemistry, Geophysics, Geosystems, 2022
The Pacific and Philippine Sea Plate subductions have resulted in and controlled the development of a typical trench‐arc‐back‐arc system in NE Asia since the Cenozoic.

The role of edge-driven convection in the generation of volcanism – Part 1: A 2D systematic study [PDF]

Solid Earth, 2021
The origin of intraplate volcanism is not explained by plate tectonic theory, and several models have been put forward for explanation. One of these models involves edge-driven convection (EDC), in which cold and thick continental lithosphere is ...

Dating volcanic materials through biochronostratigraphic methods applied to hosting strata (example from the Iberian Chain, eastern Spain)

Comptes Rendus. Géoscience, 2023
Volcaniclastic accumulations in shallow marine environments are prone to be eroded and transported by sedimentary agents and then resedimented either on contemporaneous or younger substrates. Therefore, dating of the volcanic events through the sediments

Mexican Volcanic Belt: an intraplate transform?

Geofísica Internacional, 1987
La evidencia temporal y "geométrica" sugiere que varios eventos regionales tectónicos fueron contribuyentes de mucha importancia durante la evolución del Cinturón Volcánico Mexicano (CVM). Estos incluyen (1) el desarrollo de una zona tectónica de debilidad en el área del actual CVM, seguido durante la época cenozoica por (2) actividad tectónica en la ...

Isotope-geochemical heterogeneity of pliocene-quaternary volcanics from kamchatka and the asthenospheric diapirism problem

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
Isotope-geochemical material for Pliocene-Quaternary volcanoes of the Kamchatka region is generalized on a cartographic basis. The Sr-isotope anomalies of moderate and elevated radiogenicity, geochemically confirmed, are spatially conjugated.
