Quartz-rich foliated rock, possibly milky quartz vein material

Likely quartz-rich metamorphic rock; exact identification is uncertain from the image

AI-generated identification · may be incorrect

Pale cream to white, with a rough, uneven surface and possible faint foliation or rusty mineral staining. If quartz-dominant, hardness is about 7 Mohs and luster ranges from vitreous to dull on weathered surfaces; no obvious cleavage.

Physical properties

Formation & geological history

May have formed through metamorphism or recrystallization of silica-rich material; the image alone does not establish its origin or age.

Uses & applications

Quartz-rich rocks may be collected as specimens or used as silica feedstock and, when suitable, in aggregate or decorative stone.

Geological facts

The flat, layered appearance could also indicate a different pale rock, such as weathered slate or limestone; a fresh surface and simple tests would help distinguish them.

Field identification & locations

Check hardness against glass and look for fizzing with dilute acid: quartz scratches glass and does not fizz, while calcite-rich limestone fizzes. Common quartz-rich rocks occur in many mountain belts and vein systems.
