Physical properties
Hardness of 6-7 on Mohs scale due to quartz content; varies in color from tan, brown, yellow to red; dull luster; granular texture.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in various environments like deserts, rivers, and beaches.
Uses & applications
Widely used in construction as a building material, paving stone, and for manufacturing glass.
Geological facts
Sandstone formations often preserve ancient ripple marks and fossilized tracks, providing crucial clues about prehistoric environments.
Field identification & locations
Identified by its visible sand grains and gritty texture; commonly found worldwide in sedimentary basins and escarpments.
