  2. Fractional crystallization (geology) - Wikipedia

    en.wikipedia.org/wiki/Fractional_crystallization...

    In essence, fractional crystallization is the removal of early formed crystals from an originally homogeneous magma (for example, by gravity settling) so that these crystals are prevented from further reaction with the residual melt. [3] The composition of the remaining melt becomes relatively depleted in some components and enriched in others ...

  3. Prince Rupert's drop - Wikipedia

    en.wikipedia.org/wiki/Prince_Rupert's_drop

    Prince Rupert's drops. Prince Rupert's drops (also known as Dutch tears or Batavian tears) [1][2] are toughened glass beads created by dripping molten glass into cold water, which causes it to solidify into a tadpole -shaped droplet with a long, thin tail. These droplets are characterized internally by very high residual stresses, which give ...

  4. Magma - Wikipedia

    en.wikipedia.org/wiki/Magma

    Magma (sometimes colloquially but incorrectly referred to as lava) 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.

  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. Crystal mush - Wikipedia

    en.wikipedia.org/wiki/Crystal_mush

    A crystal mush is magma that contains a significant amount of crystals (up to 50% of the volume) suspended in the liquid phase (melt). [1] As the crystal fraction makes up less than half of the volume, there is no rigid large-scale three-dimensional network as in solids. [2] As such, their rheological behavior mirrors that of absolute liquids.

  7. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Crystallization. Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors ...

  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. The sequence of (usually increasingly silicic) magmas produced by igneous differentiation is ...

    Uric acid forms crystals around joints in the body, most commonly in the big toe or knee, but can be found in any joint. When this occurs, the affected joint results in severe pain, swelling and ...
