Physical properties
Hardness of 6-7 on the Mohs scale, brown color due to iron oxide staining, dull to earthy luster, and quartz-dominated granular structure.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert or river environments over millions of years.
Uses & applications
Commonly used in construction, paving, decorative architecture, and landscaping.
Geological facts
Sandstone formations often preserve ancient ripple marks and fossilized footprints from prehistoric eras.
Field identification & locations
Identified by its gritty texture and visible sand grains; widely distributed globally in sedimentary basins.
