Physical properties
Hardness of 6-7 on Mohs scale depending on cement. Colors include tan, brown, yellow, red, and grey. Dull to earthy luster with clastic texture.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years.
Uses & applications
Widely used in construction as a building material, paving stone, and for decorative facing.
Geological facts
Sandstone formations often preserve ancient desert dunes or riverbeds and can store vast amounts of groundwater as aquifers.
Field identification & locations
Easily identified by its gritty texture resembling sandpaper and visible quartz grains. Common worldwide in deserts, river basins, and coastal regions.
