Quartz Mineral Photos, Uses, Properties, Pictures
What is Quartz? Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO 2).It is the most abundant mineral found at Earth's surface, and its unique properties make it one of the most useful natural substances.
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO 4 siliconoxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.

The association of gold and quartz veins is a well known example. Quartz is the most common 'gangue mineral' in ore deposits. Quartz Crystals Quartz crystals typically grow in fluids at elevated temperatures between 150176;C and 600176;C, but they also grow at ambient conditions (Mackenzie and Gees, 1971; Ries and Menckhoff, 2008).
colored varieties of quartz Mineral Spectroscopy
Iron containing varieties Amethyst Large geodes of amethyst occur in basalts in southern Brazil and northern Uraguay. The color of amethyst is the result of radiation damage to Fe 3+ in the interstitial site of quartz. The radiation could be due to gamma rays from 40 K. Current theory says that the ferric iron is oxidized to Fe 4+ by the gamma rays.

Quartz veins are also important host rocks for gold and other precious metals, and were the target of many mining rushes. From a historic perspective, however, the single most important use of quartz may have been to start fires. When chert is struck against iron, it produces a relatively long lived spark.
