Physical properties

Hardness: 6-7 (if quartz-rich); Color: Tan, beige, brown; Luster: Dull or earthy; Crystal structure: Clastic (grainy texture); 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, oceans, or deserts. Result of weathering and erosion over millions of years.

Uses & applications

Commonly used in construction as a building material, paving, and decorative stone. Sometimes used for glass manufacturing if silica content is exceptionally high.

Geological facts

Sandstone accounts for roughly 20 to 25 percent of all sedimentary rocks on Earth. The grains are often held together by silica, calcite, or iron oxide cement.
