Physical properties
Hardness of 6-7 on Mohs scale depending on cement, typically tan or reddish-brown in color, dull luster, granular texture composed of quartz and feldspar grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in desert, river, or marine environments over millions of years.
Uses & applications
Widely used in construction as a building and dimension stone, paving, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, acting as major global reservoirs. Famous monuments worldwide, including Petra in Jordan, are carved directly into sandstone cliffs.
Field identification & locations
Easily identified by its visible sand-grained texture and layered bedding planes. Found worldwide in sedimentary basins and arid or coastal regions.
