Physical properties
Mohs hardness of 6 to 7. Tan, brown, or reddish color with a dull to vitreous luster and granular texture.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, over millions of years.
Uses & applications
Widely used in construction as a building material, for paving, and in the manufacture of glass.
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 gritty, sandpaper-like texture and visible sand grains; commonly found in deserts, riverbeds, and ancient marine basins.
