Physical properties
Hardness of 6-7 on the Mohs scale due to quartz content, tan to brown or reddish color, dull or earthy luster, clastic texture composed of sand-sized mineral grains or rock fragments, specific gravity around 2.2-2.8.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, often in environments such as deserts, rivers, and beaches over millions of years.
Uses & applications
Widely used in construction, building facades, paving stones, and formerly for grindstones.
Geological facts
Sandstone is porous and acts as a major aquifer for groundwater storage as well as a reservoir rock for petroleum and natural gas.
Field identification & locations
Identified by its visible or tactile sandy texture and layered clastic grains. Found globally in sedimentary basins.
