What's the difference between granite and mica?

Granite


Definition:

  • (n.) A crystalline, granular rock, consisting of quartz, feldspar, and mica, and usually of a whitish, grayish, or flesh-red color. It differs from gneiss in not having the mica in planes, and therefore in being destitute of a schistose structure.

Mica


Definition:

  • (n.) The name of a group of minerals characterized by highly perfect cleavage, so that they readily separate into very thin leaves, more or less elastic. They differ widely in composition, and vary in color from pale brown or yellow to green or black. The transparent forms are used in lanterns, the doors of stoves, etc., being popularly called isinglass. Formerly called also cat-silver, and glimmer.
