Physical properties
Hardness of 6-7 on Mohs scale, tan to brown color, dull luster, clastic texture, specific gravity of 2.2-2.8.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, in marine, desert, or river environments.
Uses & applications
Widely used in construction as a building material, paving stone, and for manufacturing glass.
Geological facts
Sandstone formations can store large amounts of water, petroleum, and natural gas, making them important reservoirs for aquifers and fossil fuels.
Field identification & locations
Identified by its gritty, sandpaper-like texture and visible sand grains; commonly found in deserts, riverbeds, and ancient sea beds worldwide.
