The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having close to perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The highly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
The word "mica" is derived from the Latin word mica, meaning "a crumb", and probably influenced by micare, "to glitter".
Chemically, micas can be given the general formula
Structurally, micas can be classed as dioctahedral (Y = 4) and trioctahedral (Y = 6). If the X ion is K or Na, the mica is a "common" mica, whereas if the X ion is Ca, the mica is classed as a "brittle" mica.
Common micas:
Brittle micas:
Very fine-grained micas, which typically show more variation in ion and water content, are informally termed "clay micas". They include
Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Large crystals of mica used for various applications are typically mined from granitic pegmatites.

Plot: A small border post on the Yugoslav-Albanian border in the spring of 1987. Frustrated and always drunk, lieutenant Pasic feels a strange pain in his groins. He seeks help from the only doctor among the soldiers, Sinisa, who diagnoses a sexually transmitted disease. Not wishing his wife to know about it and trying to find excuses not to go home, he declares a state of emergency, claiming that the Albanian army is preparing an attack against Yugoslavia. A joke transforms into war hysteria: soldiers dig trenches, Pasic grows wilder as the days go by, Sinisa embarks on a dangerous liaison, and his best friend Ljuba decides to leave the army. The situation slowly runs out of control...
