Crystal Definition, Examples, and Common Types
WebCrystals form within the magma as it begins to solidify, of which the speed of cooling can dictate the size of the crystals that form. A close up view of porphyritic granite, a type of igneous rock. Porphyritic granite occurs when the temperature of the magma cooling changes quickly. In this instance, large crystals were allowed to form with ... WebDefinition of crystal form. i. The form or shape in which crystals naturally grow; eg. the cube, the octahedron, and others. ii.
