Physical properties

Hardness of 6 to 7 on the Mohs scale, predominantly tan to yellow-brown color, dull luster, clastic or granular texture with quartz grains, and a specific gravity of 2.2 to 2.8.

Formation & geological history

Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz sand, in environments like deserts, rivers, and beaches over millions of years.

Uses & applications

Commonly used in construction as a building material, dimension stone, paving, and in the manufacturing of glass and abrasives.

Geological facts

Sandstone formations can act as excellent aquifers for groundwater storage due to their porous nature, and famous monuments like Petra are carved directly into sandstone cliffs.

Field identification & locations

Easily identified by its gritty, sandpaper-like texture and visible mineral grains, and is found worldwide in sedimentary basins and geological strata.
