Crystallization geology example
WebThe individual crystals in an aphanitic igneous rock are not distinguishable to the naked eye. Examples of aphanitic igneous rock include basalt, andesite and rhyolite. Glassy or vitreous textures occur during some volcanic eruptions when the lava is quenched so rapidly that crystallization cannot occur. The result is a natural amorphous glass ... WebIn geology, re-crystallization refers to the metamorphic process, which occurs under different situations of high and intense temperature along with pressure where atoms and …

WebApr 4, 2024 · Crystal settling is a term used in geology that refers to the process by which crystals (solid materials) settle through a liquid or gaseous medium and form layers along the surface. It is usually used to describe … WebThe resulting rock will be fine-grained (i.e., crystals less than 1 mm). If the cooling is slow (from decades to millions of years), the degree of ordering will be higher and relatively large crystals will form. In some cases, the cooling will be so fast (seconds) that the texture will be glassy, which means that no crystals at all form.
