Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. It typically appears white, clear, or stained with iron oxides.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich fluids or magma over geological timescales.
Uses & applications
Used extensively in electronics, glassmaking, abrasives, and ornamental jewelry due to its piezoelectric properties and durability.
Geological facts
Quartz is one of the most abundant and ubiquitous minerals in the Earth's continental crust. Its high resistance to weathering allows it to persist in soils and sedimentary rocks.
Field identification & locations
Easily identifiable in the field by its characteristic hardness, lack of cleavage, and ability to scratch glass. Found globally in almost all geological settings.
