Physical properties

Hardness: 6-7 (Mohs scale), Color: tan, yellow, buff; Luster: matte/dull; Crystal structure: granular/clastic; Cleavage: none (breaks across grains); Specific gravity: 2.0-2.6

Formation & geological history

Formed through the accumulation, compaction, and lithification of sand-sized mineral particles or rock fragments. Typically deposited in riverbeds, deserts, or coastal environments over millions of years.

Uses & applications

Widely used in construction for grindstones, building facades, and paving; also used as an aquifer for groundwater and an industrial source of silica sand for glassmaking.

Geological facts

Sandstone captures a 'snapshot' of ancient history; cross-bedding within sandstone layers can reveal the direction of wind or water currents from millions of years ago.

Field identification & locations

Identify by its gritty texture (feels like sandpaper) and visible sand grains. Commonly found in canyons, river valleys, and sedimentary basins worldwide.
