Physical properties
Hardness: 6-7 on the Mohs scale depending on cementation; Color: Light brown to tan; Luster: Dull, earthy; Texture: Granular, coarse; Specific Gravity: 2.2-2.8
Formation & geological history
Formed by the compaction and cementation of mineral particles or rock fragments, typically composed of quartz and feldspar, deposited in desert, river, or coastal environments over millions of years.
Uses & applications
Widely used as a construction material, paving stone, decorative building veneer, flagstone, and crushed stone for road bases.
Geological facts
Sandstone often preserves sedimentary structures such as ripple marks and cross-bedding, offering important clues about ancient climate and water/wind currents.
Field identification & locations
Identified in the field by its gritty texture (feels like sandpaper) and visible sand-sized mineral grains. Commonly found in sedimentary basins, canyons, and cliff faces worldwide.
