Hydrothermal. Alteration of a Variscian Granite, Magmatic Autometasomatism and Fault Related Vein Metasomatism

1987
Two types of hydrothermal alteration can be recognized in a biotite granite of Variscan age in Northern Switzerland. The first is related to the intrusion of the granite and lead to the replacement of K-spar and biotite by muscovite, of plagioclase by sericite and calcite and to a chloritization of biotite. This process affected the granite as a whole.
