  2. 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 .

  3. Magma - Wikipedia

    en.wikipedia.org/wiki/Magma

    Magma (sometimes colloquially but incorrectly referred to as lava by laypeople) is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. [3] Besides molten rock, magma may also contain suspended crystals and gas bubbles.

  4. Tholeiitic magma series - Wikipedia

    en.wikipedia.org/wiki/Tholeiitic_Magma_Series

    The tholeiitic magma series ( / ˌθoʊliˈaɪtɪk /) is one of two main magma series in subalkaline igneous rocks, the other being the calc-alkaline 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 ...

  5. Magmatic water - Wikipedia

    en.wikipedia.org/wiki/Magmatic_water

    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. It plays a key role in assessing the crystallization of igneous rocks, particularly silicates, as well as the ...

  6. Sill (geology) - Wikipedia

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

    Sill (geology) Illustration showing the difference between a dike and a sill. In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A sill is a concordant intrusive sheet, meaning that it does not cut ...

  7. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights. For the short-lived elements ...

  8. Pegmatite - Wikipedia

    en.wikipedia.org/wiki/Pegmatite

    Pegmatite. A pegmatite is an igneous rock showing a very coarse texture, with large interlocking crystals usually greater in size than 1 cm (0.4 in) and sometimes greater than 1 meter (3 ft). Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite.

  9. Extrusive rock - Wikipedia

    en.wikipedia.org/wiki/Extrusive_rock

    Shield volcanoes are large, slow forming volcanoes that erupt fluid basaltic magma that cools to form the extrusive rock basalt. Basalt is composed of minerals readily available in the planet's crust, including feldspars and pyroxenes. Fissure volcanoes pour out low viscosity basaltic magma from fissure vents to form the extrusive rock basalt.
