(ˈmæɡmə)

n, pl -mas or -mata (-mətə)

1. (General Physics) a paste or suspension consisting of a finely divided solid dispersed in a liquid

2. (Geological Science) hot molten rock, usually formed in the earth's upper mantle, some of which finds its way into the crust and onto the earth's surface, where it solidifies to form igneous rock

mag•ma

(ˈmæg mə)

n., pl. -mas, -ma•ta (-mə tə)

1. molten material beneath or within the earth's crust, from which igneous rock is formed.

2. a mixture or suspension of mineral or organic matter.

[1400–50; < Latin < Greek mágma salve]

mag•mat′ic (-ˈmæt ɪk) adj.

mag·ma

(măg′mə)

The molten rock material that originates under the Earth's crust and forms igneous rock when it has cooled. When magma cools and solidifies beneath the Earth's surface, it forms what are known as intrusive rocks. When it reaches the Earth's surface, it flows out as lava and forms extrusive (or volcanic) rocks.

'It is very important to realise that in huge and complex volcanic systems, such as the Karoo province, large amounts of magmas may be produced from several magma sources', explains Daud Jamal, professor at the Eduardo Mondlane University, in Mozambique.

As well as the initiation of eruptions, the new mush reservoir model can help explain other phenomena in volcanic systems, such as how the magma chemical composition evolves and how much older crystals can be erupted within younger magmas.

Volcanoes Fed by 'Mush' Reservoirs

Dr Ubide said: "Just as investigators reconstruct events to learn the truth, we prise magma injections from the crystals that are transported to the surface by erupted magmas to do the same thing.

A catastrophic eruption discharges voluminous magmas from a large magma reservoir, causing the roof to collapse forming a caldera.

The hotter magma from down deep warms the cooler magma stored at 4-5 kilometers, making it possible for both magmas to mix and to be transported to the surface to eventually produce an eruption.

Dormant volcanoes can become active quickly

show that differentiation from mafic to intermediate and felsic magmas in some arc volcanoes may be an unexpectedly rapid process.

Dynamics of Crustal Magma Transfer, Storage and Differentiation

At what rates and through what mechanisms do magmas ascend through the Earth's crust?

Dynamics of crustal magma transfer, storage and differentiation

Volcanoes erupting relatively metal-rich, silica- and volatile-poor magmas (called basalts) tend to concentrate along the midocean ridges, which mark the constructional margins of Earth's rigid crust plates.

Planetary Volcanism

The mechanism by which magma migrates depends on the properties of the magmas and conditions in the crust.

Magmatic and volcanic activity that creates oceanic crust plays an important role in controlling the fluxes of elements and heat in the oceans, and it was the degassing of magmas on Earth's surface that gave rise to the oceans and atmosphere in the first place.

Oceanic crust composition and structure

This latest study, which also included researchers from Northwestern University and the Carnegie Institution of Washington, indicated that under conditions like those found in the mantles of Mars, the Moon and other bodies, carbon is trapped in the magmas mainly as a species called iron carbonyl and released as carbon monoxide and methane gas.

Mars may have been warm enough to support liquid water

"Degassing from magmas is a very reasonable means" for producing water on ancient Mars, notes Victor R.
