Physical properties
Hardness of 6 to 7 on the Mohs scale, typically brown, tan, or reddish in color with a dull luster and quartz-rich composition.
Formation & geological history
Formed through 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, dimension stone, and for making grindstones.
Geological facts
Sandstone formations can store vast amounts of groundwater and often act as natural petroleum reservoirs.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, commonly found in desert environments and ancient riverbeds.
