Physical properties
Hardness of 7 on the Mohs scale, predominantly brown to tan due to iron oxide staining, dull to vitreous luster, clastic texture with rounded quartz grains, poor to absent cleavage, specific gravity around 2.65.
Formation & geological history
Formed from the accumulation, compaction, and cementation of sand-sized mineral particles (mostly quartz) in marine, desert, or river environments over millions of years.
Uses & applications
Used primarily in construction, as dimension stone, for landscaping, and occasionally in glassmaking.
Geological facts
Many famous geological formations worldwide, such as desert arches and canyon walls, are composed of weathered sandstone that has been sculpted by wind and water erosion over vast timescales.
Field identification & locations
Easily identified by its gritty texture and visible sand grains or rounded weathering shapes, commonly found in sedimentary basins and exposed cliff faces worldwide.
