Small quartz-rich rock fragment (possibly weathered quartz vein material)
Quartz (SiO₂) in an undetermined host rock; the image is insufficient to identify the host confidently
AI-generated identification · may be incorrectSmall, angular gray-beige fragment with pale, glassy-looking grains. Quartz has Mohs hardness 7, vitreous luster, and a hexagonal crystal structure; no clear cleavage. The specimen’s grain size and specific gravity cannot be determined from this photo.

Physical properties
Small, angular gray-beige fragment with pale, glassy-looking grains. Quartz has Mohs hardness 7, vitreous luster, and a hexagonal crystal structure; no clear cleavage. The specimen’s grain size and specific gravity cannot be determined from this photo.
Formation & geological history
Likely a naturally broken and weathered fragment of quartz-bearing rock; its age and precise formation history cannot be established visually. Quartz veins and quartz-rich rocks are common in the broader region of eastern Morocco.
Uses & applications
Quartz-bearing rock is used in construction and as a silica source; this small, unverified fragment has no evident commercial or jewelry value.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly fills fractures as veins.
Field identification & locations
Look for glassy grains and hardness: quartz can scratch ordinary glass and does not show cubic cleavage. A closer view and simple hardness tests would help distinguish vein quartz from a quartz-rich host rock.
