Sandstone with Quartz Vein

Quartz-veined Arenite (SiO2 in detrital quartz matrix)

AI-generated identification · may be incorrect

Hardness of 7 for the quartz vein and 6-7 for the sandstone host. Colors range from tan to reddish-brown with a white/translucent vein. Luster is vitreous in the vein and dull/earthy in the sandstone.

Physical properties

Hardness of 7 for the quartz vein and 6-7 for the sandstone host. Colors range from tan to reddish-brown with a white/translucent vein. Luster is vitreous in the vein and dull/earthy in the sandstone.

Formation & geological history

Formed through the lithification of sand-sized mineral particles, later fractured and hydrothermally injected with silica-rich fluids that precipitated quartz.

Uses & applications

Used primarily in educational geology collections, decorative landscaping, and as building stone.

Geological facts

Mineral veins like this form when hydrothermal fluids travel through fractures in the Earth's crust, cooling to leave mineral deposits behind.

Field identification & locations

Identify by observing a contrasting mineral infill cutting across sedimentary bedding planes. Found worldwide in sedimentary basins.
