Physical properties
Hardness of 6-7 on the Mohs scale, typically pinkish-red to brown color with a dull luster and a granular, clastic texture.
Formation & geological history
Formed by 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 paving or landscaping.
Geological facts
Sandstone formations often preserve ancient desert or river environments and can store vast amounts of groundwater.
Field identification & locations
Easily identified by its visible sand grains and gritty texture; commonly found in riverbeds, deserts, and sedimentary basins worldwide.
