Physical properties

Hardness: 6-7 on Mohs scale; Color: Tan, beige, or light brown; Luster: Dull to earthy; Crystal structure: Granular/Clastic; Cleavage: None; Specific gravity: 2.2-2.8

Formation & geological history

Formed through the accumulation and cementation of sand-sized mineral grains or rock fragments, typically in river beds, beaches, or deserts. This specific smooth, water-worn shape suggests a river or coastal origin.

Uses & applications

Used widely as a construction material (dimension stone), in glass manufacturing if silica content is high, and as an abrasive in industrial applications.

Geological facts

Sandstone makes up about 20% of all sedimentary rocks on Earth. Famous structures like Petra in Jordan and the Grand Canyon are primarily composed of various sandstone layers.

Field identification & locations

Identify by its gritty texture (feels like sandpaper) and visible sand grains. Found globally in basins and coastal areas. Commonly used for landscaping and garden paths.
