WitrynaQuartz is a common and often essential mineral in a wide variety of sedimentary, metamorphic and igneous rocks. It is always nearly pure SiO 2. Keys to identification are:colorless nature, first order white-gray interference colors, and undulatory extinction. It also lacks cleavage , twinning and alteration.
