Description

Quartz, as the second most abundant mineral on Earth, makes up 12% of the crusts mass. Its structure consists of silicon tetrahedra arranged in an interlocking, spiral pattern that forms parallel to the c-axis. Quartz belongs to the hexagonal crystal system and is most commonly shaped like a prism with two rhombohedra on either end. The robust structure of quartz makes it resistant to weathering and chemical erosion, making it one of the most stable minerals. With its wide array of polymorphs, quartz has many uses technologically and commercially, from high end watch faces and gemstones to abrasives, glass making and oscillator plates for radios. Since quartz properties change depending on pressure and temperature conditions, it provides useful information about geological processes.
