Physical properties
Hardness is typically 6 to 7 on the Mohs scale depending on cementation. Colors range from tan, brown, yellow, and red to grey.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, mainly quartz and feldspar, in marine, desert, or river environments.
Uses & applications
Widely used in construction as a building material, dimension stone, and for paving. Also utilized in the manufacture of glass and abrasives.
Geological facts
Sandstone formations often preserve ancient ripple marks and fossilized tracks, providing a clear record of prehistoric environments.
Field identification & locations
Easily identified by its visible grainy texture and gritty feel. Common worldwide in desert regions, canyons, and ancient riverbeds.
