Physical properties

Hardness: 6.5-7 (vein), 6-7 (matrix); Color: Tan to reddish-brown with white vein; Luster: Dull/Earthy matrix, Vitreous vein; Texture: Granular/Clastic

Formation & geological history

Formed through the accumulation and cementation of sand-sized mineral grains or rock fragments, predominantly quartz. The white vein formed later via hydrothermal activity or mineral-rich water filling a fracture. Likely Paleozoic or Mesozoic age depending on local stratigraphy.

Uses & applications

Primarily used as a decorative garden stone, building material (when in larger blocks), or educational specimen for demonstrating rock fracturing and secondary mineral deposition.

Geological facts

The 'bulging' look of the white vein occurs because the quartz is more resistant to weathering/erosion than the surrounding sandstone matrix, causing it to stand out in relief.

Field identification & locations

Found globally in sedimentary basins. Identify in the field by looking for sandy textures and layers; veins are recognized as distinct linear mineral fills cutting across the primary bedding.
