silicic magmas have a silica content greater than 63%. They include rhyolite and dacite magmas. With such a high silica content, these magmas are extremely

is a function from X to any magma N, then there is a unique extension of f to a morphism of magmas f′ f′ : MX → N. Magmas are not often studied as such;

of magmas, with magmas as objects and morphisms given by homomorphisms of operations Magma (band), a French experimental progressive rock band Magma (Magma

In mathematics, there exist magmas that are commutative but not associative. A simple example of such a magma may be derived from the children's game

calc-alkaline magma series by the redox state of the magma they crystallized from (tholeiitic magmas are reduced; calc-alkaline magmas are oxidized )

A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding

masses occur with granite. Granite forms from silica-rich (felsic) magmas. Felsic magmas are thought to form by addition of heat or water vapor to rock of

Magma is the self-titled debut album by French rock band Magma. Released as a double-LP in 1970, it is a concept album which tells the story of a group

Eckmann–Hilton argument. Another class of semigroups forming medial magmas are normal bands. Medial magmas need not be associative: for any nontrivial abelian group

Hydrous magmas composed of basalt and andesite are produced directly and indirectly as results of dehydration during the subduction process. Such magmas, and
