Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation; typically red, brown, or tan; dull to earthy luster; composed mostly of quartz grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years.
Uses & applications
Commonly used in construction, paving, dimension stone, and landscaping.
Geological facts
Sandstone formations often preserve ancient desert dunes and riverbeds, providing vital clues about Earth's paleoclimate.
Field identification & locations
Easily identified by its visible sand grains and layered sedimentary bedding planes; found worldwide in arid regions and ancient river valleys.
