Physical properties
Mohs hardness of 6 to 7. Color ranges from brown, tan, yellow, to red due to iron oxides. Dull luster with clastic texture.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, mostly quartz and feldspar, over millions of years.
Uses & applications
Commonly used in construction as a building material, paving stone, and for making glass.
Geological facts
Sandstone formations often preserve ancient desert environments and ripple marks from ancient water bodies.
Field identification & locations
Identified by its gritty texture, visible sand grains, and layered appearance. Found globally in deserts, riverbeds, and ancient sea beds.
