Formation & geological history

Formed through the accumulation and cementation of mineral particles (detritus) or rock fragments. Likely deposited in a high-energy environment such as a river bed (fluvial) or shoreline, where smaller particles are washed away.

Uses & applications

Used widely in construction as a building stone (dimension stone), as a source of silica for glass making, and for pavers or landscaping.

Geological facts

Sandstone is often porous enough to act as a reservoir for water (aquifers) or oil and gas. It often preserves sedimentary structures like ripple marks or cross-bedding.
