Melt inclusions reveal massive carbon dioxide emissions from continental intraplate volcanism

Communications 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.

Recent volcanism in relation to plate interaction and deep-level geodynamics

, 2010
The spatial distribution of recent (under 2 Ma) volcanism has been studied in relation to mantle hotspots and the evolution of the present-day supercontinent which we named Northern Pangea. Recent volcanism is observed in Eurasia, North and South America,

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

Latin 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

Earth 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.

Exploring the impacts of mantle flow on the formation of intraplate volcanism in Mongolia

Theories for intraplate volcanism can be divided into two groups: the first being an active dynamic process of upwelling mantle plumes, and the second being passive responses to broader processes, e.g., delamination or edge convection. In the category of

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

Geochemistry, 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

Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

Geochemistry, Geophysics, Geosystems
Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis ...

Geochemical expression of volcanism in an on-axis and intraplate hotspot : Cobb and Marquesas

The Pacific Ocean basin is home to a set of hotspots diverse in their eruption rate, duration of volcanism, and basalt chemistry. Pacific hotspots are found in a spectrum of distinct plate tectonic settings, from near a spreading ridge to intraplate ...

Global Influence of Mantle Temperature and Plate Thickness on Intraplate Magmatism [PDF]

The thermochemical structure of lithospheric and asthenospheric mantle exert primary controls on surface topography and volcanic activity. Volcanic rock compositions and mantle seismic velocities provide indirect observations of this structure.
