Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation. Colors range from tan, brown, yellow, to red due to iron oxides, with a dull to earthy luster.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, over millions of years in various terrestrial and aquatic environments.
Uses & applications
Widely used in construction as a building material, for paving, flooring, and historically for grinding stones.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, making them crucial reservoir rocks for energy and aquifers.
Field identification & locations
Identified by its visible sand-sized grains and gritty texture; commonly found in deserts, riverbeds, and ancient marine basins worldwide.
