Crystalline characteristics
Crystals are commonly recognized, macroscopically, by their shape, consisting of flat faces with sharp angles. These shape characteristics are not necessary for a crystal—a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape—but the characteristic macroscopic shape is often present and easy to see. Webcrystalline rock, any rock composed entirely of crystallized minerals without glassy matter. Intrusive igneous rocks —those that congeal at depth—are virtually always crystalline, whereas extrusive igneous rocks, or …
