See all on Wikipediahttps://en.wikipedia.org/wiki/BiotiteBiotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe) 3AlSi 3O 10(F,OH) 2. It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include … See more
Like other mica minerals, biotite has a highly perfect basal cleavage, and consists of flexible sheets, or lamellae, which easily flake off. It has a monoclinic crystal system, with tabular to prismatic crystals with an obvious See more
Biotite is used extensively to constrain ages of rocks, by either potassium-argon dating or argon–argon dating. Because argon escapes readily from the biotite crystal structure at high temperatures, these methods may provide only minimum ages for many … See more
Members of the biotite group are found in a wide variety of igneous and metamorphic rocks. For instance, biotite occurs in the lava of Mount Vesuvius and in the Monzoni intrusive complex of … See more

- https://it.wikipedia.org/wiki/BiotiteSee more on it.wikipedia.orgLa biotite è una mica piuttosto comune in molti tipi di rocce tra cui: rocce intrusive, effusive, sedimentarie e metamorfiche. Alcune lamelle di biotite alterate, lucenti come l'oro per separazione di ossidi di ferro, sono state riscontrate in alcuni tipi di sabbia e così può capitare di far confondere il minerale con l'oro.
