vapour-phase crystallization The crystallization of minerals from hot gases escaping through a volcanic body. Cooling of the escaping gases, which carry elements in solution, promotes the crystallization of minerals in rock cavities or the spaces between pyroclastic clasts in ignimbrites. Minerals such as feldspar and quartz are common vapour-phase crystallization products.
