		Quartz occurs in two distinct types, the macrocrystalline and the cryptocrystalline varieties, the latter often being classed as chalcedony.
		Macrocrystalline quartz is generally rather easily recognized by its crystal form, hardness, and lack of cleavage; chalcedonic varieties are identified by their hardness and typical dense structure.
		Quartz is stable over practically the whole range of geological conditions, and because 5i02 is the most abundant oxide in the earth’s crust, it is a very common mineral.
