Polymineralic means having more than one mineral.
These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals.

Magnesite is a mineral not a rock and pure gypsum is also a mineral (composed of sulphate i.e. CaS04.2H20).
Quartzite is monomineralic consisting quartz, whereas granites have quartz, feldspar & mica.
