Quartzes and quartzites belong among the sediments with grain size between 0.05 to 2 mm where the individual grains are layered and form a variable structure. While quartz is classed as a mineral, quartzite is included among the ores. Quartzites contain mainly quartz grains, which make up to 95% of all grains.

The mineralogy of sandstones: Quartz grains

Strained quartz: Source rocks under stress (tectonic, metamorphic) will have some strain partitioned to their crystal frameworks.Distortion of the crystal lattice in strained monocrystalline quartz results in wavy or uneven extinction across grains. If strain has completely disrupted the crystal lattice, then the once monocrystalline quartz will be …

Quartz | Definition, Types, Uses, & Facts | Britannica

Quartz exists in two forms: (1) alpha-, or low, quartz, which is stable up to 573 °C (1,063 °F), and (2) beta-, or high, quartz, stable above 573 °C.The two are closely related, with only small movements of their constituent atoms during the alpha-beta transition. The structure of beta-quartz is hexagonal, with either a left- or right-handed symmetry group …
