  2. Intrusive rock - Wikipedia

    en.wikipedia.org/wiki/Intrusive_rock

    Intrusion is one of the two ways igneous rock can form. The other is extrusion, such as a volcanic eruption or similar event. An intrusion is any body of intrusive igneous rock, formed from magma that cools and solidifies within the crust of the planet. In contrast, an extrusion consists of extrusive rock, formed above the surface of the crust.

    The term pluton is poorly defined, [12] but has been used to describe an intrusion emplaced at great depth; [13] as a synonym for all igneous intrusions; [14] as a dustbin category for intrusions whose size or character are not well determined; [15] or as a name for a very large intrusion [16] or for a crystallized magma chamber. [17]

  4. Extrusive rock - Wikipedia

    en.wikipedia.org/wiki/Extrusive_rock

    Shield volcanoes are large, slow forming volcanoes [6] 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.

  5. Magmatism - Wikipedia

    en.wikipedia.org/wiki/Magmatism

    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. Magmatism is one of the main processes responsible for mountain formation. The nature of magmatism depends on the tectonic setting. [1]

  6. Sill (geology) - Wikipedia

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

    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 across preexisting rock beds.

  7. Intrusion (orthodontics) - Wikipedia

    en.wikipedia.org/wiki/Intrusion_(orthodontics)

    Intrusion is a movement in the field of orthodontics where a tooth is moved partially into the bone. Intrusion is done in orthodontics to correct an anterior deep bite or in some cases intrusion of the over-erupted posterior teeth with no opposing tooth. [1] Intrusion can be done in many ways and consists of many different types.

  9. Extrusion - Wikipedia

    en.wikipedia.org/wiki/Extrusion

    Hot extrusion is a hot working process, which means it is done above the material's recrystallization temperature to keep the material from work hardening and to make it easier to push the material through the die. Most hot extrusions are done on horizontal hydraulic presses that range from 230 to 11,000 metric tons (250 to 12,130 short tons ...
