Physical properties
Hardness of 6-7 on Mohs scale, typically brown, tan, or reddish with a granular texture and dull luster.
Formation & geological history
Formed from the compaction and cementation of mineral particles or rock fragments, primarily quartz and feldspar, accumulating over millions of years.
Uses & applications
Widely used in construction as a building material, dimension stone, and for paving.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, making them crucial reservoir rocks.
Field identification & locations
Identify by visible sand-sized grains and distinct layering or bedding planes; commonly found in desert regions and ancient riverbeds.
