Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. [6] It is particularly prominent in many granites, pegmatites, and schists, [7] and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Visa mer Micas are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. … Visa mer The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards … Visa mer Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Large crystals of mica used for various applications … Visa mer The word mica is derived from the Latin word mica, meaning a crumb, and probably influenced by micare, to glitter. Visa mer Chemically, micas can be given the general formula X2Y4–6Z8O20(OH, F)4, in which Visa mer The commercially important micas are muscovite and phlogopite, which are used in a variety of applications.
