Physical properties
Hardness of 6 to 7 on the Mohs scale depending on cementation; typically tan, brown, yellow, or red; dull luster; composed mostly of quartz and feldspar grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in environments like deserts, rivers, and beaches.
Uses & applications
Widely used as a construction material for building, paving, and dimension stone, as well as an aquifer for groundwater storage.
Geological facts
Many of the world's most famous monuments and ancient temples are carved directly from sandstone cliffs due to its workability.
Field identification & locations
Easily identified in the field by its visible sandy grains and layered bedding planes. Found worldwide in sedimentary basins.
