Physical properties
Hardness of 7 on the Mohs scale, yellowish-brown exterior with a white to grey crystalline quartz vein, vitreous to dull luster, and conchoidal fracture.
Formation & geological history
Formed through the deposition and lithification of quartz sand grains, later fractured and infiltrated by silica-rich hydrothermal fluids that crystallized into a quartz vein.
Uses & applications
Used primarily as decorative landscape gravel, aggregate in construction, and as a collectible geological specimen.
Geological facts
Quartz veins are nature's plumbing systems, often carrying valuable hydrothermal ore minerals like gold, copper, and silver.
Field identification & locations
Easily identified in the field by contrasting mineral bands cutting through the host rock, commonly found in mountainous regions and riverbeds.
