mica rock or mineral

For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica as interlocked crystals; a sandstone is a sedimentary rock that can also contain quartz, feldspar and mica, but as grains compacted and cemented into each other. The definition of an economic mineral is broader.
