The largest amount of quartz is found as a rock-forming mineral in silica-rich igneous rocks, namely granite-like plutonic rocks, and in the metamorphic rocks that are derived from them. Under conditions at or near the surface, quartz is generally more stable than most other rock-forming minerals and its accumulation in sediments leads to rocks that are highly enriched in quartz, like sandstones.
Quartz crystal is found in many countries and many geologic environments. Major producers of natural quartz crystals are the United States (particularly Arkansas) and Brazil. Natural quartz is rarely used as found in nature (especially in electrical applications), except as a gemstone.

The types of minerals found in a vein change with distance from the pluton body, reflecting the solubility of the various compounds at different temperatures. In many cases, quartz can be found at any distance from the pluton, and often the distant ends of the veins are void of ores and simply filled with quartz.

quartz. Much of the material mined as spar is coarse-grained graphic granite containing from 10 to 20 per cent of free quartz. In the great majority of pegmatite bodies there is no regularity whatsoever in the distribution of the different minerals. The mica plates show, in many places, a tendency to group themselves along
Apr 25, 2019 Quartz. Quartz is one of the most common minerals in the Earths crust. It is made of silicon dioxide (SiO2), otherwise known as silica. Varieties of quartz based on color include amethyst (purple), smoky quartz (grey), rose quartz (pink), and citrine (yellow-green). Quartz has a glassy luster and a hardness of 7.
These associated minerals are, however, rare except for the oxides of manganese and iron, clay minerals and chlorite, so rare that specimens of them from crystal mines are unusual. The crystals occur in vugs or pockets in the milky vein quartz.
