Physical properties

Formation & geological history

Formed by the compaction and cementation of sand-sized mineral grains or rock fragments (predominantly quartz and feldspar) in fluvial, desert, or marine depositional environments over millions of years.

Uses & applications

Landscaping, ornamental garden display, decorative rock balancing/sculpture, and architectural building stone.

Geological facts

Large sandstone boulders are frequently used in hardscaping because they weather gracefully and provide natural aesthetic texture. The smaller pink quartz cobble atop it has been rounded by natural fluvial (river/beach) erosion or mechanical tumbling.

Field identification & locations

Identified by its grainy, sand-like texture (feels like sandpaper) and distinct layering or uniform fine-grained matrix. Sandstone is found abundantly in sedimentary basins worldwide.
