  2. Magma - Wikipedia

    en.wikipedia.org/wiki/Magma

    Magma can be found in the mantle or molten crust. Magma (from Ancient Greek μάγμα (mágma) 'thick unguent') is the molten or semi-molten natural material from which all igneous rocks are formed.

  3. Tholeiitic magma series - Wikipedia

    en.wikipedia.org/wiki/Tholeiitic_Magma_Series

    A magma series is a chemically distinct range of magma compositions that describes the evolution of a mafic magma into a more evolved, silica rich end member. Rock types of the tholeiitic magma series include tholeiitic basalt, ferro-basalt, tholeiitic basaltic andesite, tholeiitic andesite, dacite and rhyolite.

  4. MagmaFS - Wikipedia

    en.wikipedia.org/wiki/MagmaFS

    Magma is a distributed file system based on a distributed hash table, written in C, compatible with Linux and BSD kernels using FUSE. Terminology and basic principles [ edit ] Magma binds several hosts interconnected by a TCP/IP network to form a common storage space called a lava ring .

  5. Sill (geology) - Wikipedia

    en.wikipedia.org/wiki/Sill_(geology)

    A sill is a concordant intrusive sheet, meaning that it does not cut across preexisting rock beds. Stacking of sills builds a sill complex [1] and a large magma chamber at high magma flux. [2] In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks.

  6. Magmatic water - Wikipedia

    en.wikipedia.org/wiki/Magmatic_water

    Magmatic water, also known as juvenile water, is an aqueous phase in equilibrium with minerals that have been dissolved by magma deep within the Earth's crust and is released to the atmosphere during a volcanic eruption.

  7. Magmatism - Wikipedia

    en.wikipedia.org/wiki/Magmatism

    Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity , the production, intrusion and extrusion of magma or lava .

  8. Igneous differentiation - Wikipedia

    en.wikipedia.org/wiki/Igneous_differentiation

    Igneous differentiation. In geology, igneous differentiation, or magmatic differentiation, is an umbrella term for the various processes by which magmas undergo bulk chemical change during the partial melting process, cooling, emplacement, or eruption.

  9. Pegmatite - Wikipedia

    en.wikipedia.org/wiki/Pegmatite

    Pegmatites are the last part of a magma body to crystallize. This final fluid fraction is enriched in volatile and trace elements. The residual magma undergoes phase separation into a melt phase and a hydrous fluid phase saturated with silica, alkalis, and other elements.

  10. Volcano tectonic earthquake - Wikipedia

    en.wikipedia.org/wiki/Volcano_tectonic_earthquake

    A volcano tectonic earthquake or volcano earthquake is caused by the movement of magma beneath the surface of the Earth. [1] The movement results in pressure changes where the rock around the magma has a change in stress. At some point, this stress can cause the rock to break or move.

  11. Extrusive rock - Wikipedia

    en.wikipedia.org/wiki/Extrusive_rock

    Extrusive rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff.
