Physical properties
Hardness 6-7 on Mohs scale, tan to brown color, dull luster, clastic texture with visible sand grains, specific gravity around 2.2-2.8.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in desert, river, or beach environments.
Uses & applications
Widely used in construction as building stone, paving material, and for manufacturing aggregate and glass.
Geological facts
Sandstone formations often display prominent cross-bedding, revealing ancient wind or water flow directions.
Field identification & locations
Identify by its gritty sandpaper-like texture and visible quartz grains; commonly found globally in riverbeds and ancient sedimentary basins.
