Rocks are in general made up of two of more minerals, mixed up through geological processes. For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica, as interlocked crystals.The Gallery of Minerals With Pictures and Descriptions.,Biotite Biotite is a member of the mica branch of the silicate mineral group. It is common as a rock-forming mineral and is present in all three rock types: igneous, metamorphic, and sedimentary.

Mineral - Wikipedia

A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case.
