  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. 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 ...

  5. Magma supply rate - Wikipedia

    en.wikipedia.org/wiki/Magma_supply_rate

    Applications. The magma supply rate is used to infer the behaviour of volcanic systems which erupt periodically, as well as to describe the growth of the continental crust and of deep-seated magmatic bodies such as plutons. [3] Magma output is usually larger in oceanic settings than in continental ones, and basaltic volcanic systems produce ...

  6. Magma chamber - Wikipedia

    en.wikipedia.org/wiki/Magma_chamber

    Magma chamber. 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 country rock, which produces buoyant forces on the magma that tend to drive it upwards. [1] If the magma finds a path to the surface, then the result will be a volcanic ...

  7. Magmatism - Wikipedia

    en.wikipedia.org/wiki/Magmatism

    Not to be confused with Magnetism. 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. Volcanism is the surface expression of magmatism.

  8. Dike (geology) - Wikipedia

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

    Magma rising into the ring fracture produces a ring dike. Good examples of ring dikes and cone sheets are found in the Ardnamurchan peninsula of Scotland. Other special types. A feeder dike is a dike that acted as a conduit for magma moving from a magma chamber to a localized intrusion.

  9. Large igneous province - Wikipedia

    en.wikipedia.org/wiki/Large_igneous_province

    A large igneous province (LIP) is an extremely large accumulation of igneous rocks, including intrusive (sills, dikes) and extrusive (lava flows, tephra deposits), arising when magma travels through the crust towards the surface.

  10. Oceanic crust - Wikipedia

    en.wikipedia.org/wiki/Oceanic_crust

    Oceanic crust is the uppermost layer of the oceanic portion of the tectonic plates. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. [1] [2] The crust overlies the rigid uppermost layer of the mantle.

  11. Volcanic plug - Wikipedia

    en.wikipedia.org/wiki/Volcanic_plug

    A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile -charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption.
