Please clear my doubts.

The mica group of sheet silicate [phyllosilicate] minerals includes severals closely related material having highly perfect basal cleavage. All are monoclinic with a tendency towards pseudohexagonal crystal and are similar in chemical.

Compsition. The highly perfect cleavage, which is the most prominent characteristic of mica is explain by the hexagonal sheet like arrangement of its atoms. The words "mica"is drived from the Latin word mica meaning "a Crumb"and probably influenced by micare, "to glitter.
