    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.

  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.

    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.

  7. 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.
