Mica is fairly widespread and occurs in igneous, metamorphic and sedimentary rocks. Large mica crystals are typically mined from granitic pegmatites. Only very few crystals are industrially mined. Muscovite white mica is the most common commercial form, accounting for 90 % of global consumption, followed by phlogopite, a bronze-colored variety.
Mica (mineral) La mica es un mineral de poca dureza que se separa fácilmente en delgadas laminas flexibles, desde traslúcidas hasta transparentes.

Los miembros principales del grupo son la moscovita, la biotita, la flogopita y la ...
Minerales de Mica. Los minerales de Mica hace que las rocas brillen. Generalmente se les encuentra en las rocas ígneas tales como el granito y las rocas metamórficas como el Esquisto. Brillan porque la luz se refleja en sus superficies planas, que es donde el mineral se fractura a lo largo de su hendidura plana.
