Albitization —introduction of, or replacement by, albite, usually replacing a more calcic plagioclase.
Amphibolization —introduction of, or replacement by, amphibole minerals.
Analcimization —replacement of feldspars or feldspathoids by analcime (analcite) usually in igneous rocks during late- and postmagmatic stages.
Autometamorphism —alteration of an igneous rock by the action of its own volatile constituents (e.g., serpentinization of peridotite, saussuritization and uralitization of gabbro); the process is deuteric rather than metamorphic.
Biotitization —introduction of, or replacement by, biotite.
Chloritization —introduction of, or replacement by, chlorite.
Damouritization —the process whereby the aluminous silicates (e.g., feldspars) of a rock are transformed into damourite (a variety of muscovite).
Deuteric alteration(synantexis)—alteration in an igneous rock produced during the later stages,...
