In underground mining,the quartz crystals are identified by the different mining methods like shaft and tunnel mining, roof and pillar mining and through the slope mining. For the extraction of the crystal, the rock which comprises the quartz crystal is allowed to decompose in the process of weathering.
Apr 12, 2017 Identifying Granite. Check the color of the rock you suspect is granite. Color is determined by mineral content. Granite is made mainly of quartz, feldspar, biotite and muscovite it sometimes also contains hornblende, augite, magnetite or zircon.
