The magma becomes contaminated with material from the crust when it absorbs part of the rock it passes through. However, neither of these processes would change the chemical composition of the magma ...

Le groupe Magma, fondé en 1969 par le batteur et compositeur Christian Vander et le bassiste Laurent Thibault, est l'un ...
They looked at the composition, structure, and history of rocks deep beneath the Earth's crust, alongside information gathered from active volcanoes, to understand how magma builds up and behaves ...
This encompasses the generation of magma, its geochemistry and movement through the Earth’s crust, the physics of volcanic eruptions and hazards including ash clouds and pyroclastic flows The ...
Kimberlites are rather susceptible to alterations that modify their original composition. Even though this pipe appears fresh there has been some debate about whether the saltiness of the magma ...
A study based on the sampling and analysis of volcanic ash at Cumbre Vieja volcano in the Canary Islands, located off Africa's northwest coast, suggests that the composition of magma could drive ...
Les dernières études [basées sur les anciennes éruptions de la Soufrière] ont montré que si on avait une réinjection de magma et que ... de la composition de gaz qui devient plus magmatique ...
L’étude de cristaux provenant du réservoir du volcan romain montre que son magma, bien que peu visqueux, contenait beaucoup de gaz. Ce qui explique l’éruption explosive très violente d’il y a 355’000 ...
The similarity in basalt composition between the far and near sides indicates that a global magma ocean may have spanned the entire moon," said Che Xiaochao, a researcher at the institute.
