Physical properties
Hardness of 6-7 on Mohs scale, tan or yellowish-brown color, dull luster, granular crystal structure, poor cleavage, specific gravity of 2.2-2.8.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in marine, desert, or river environments over millions of years.
Uses & applications
Widely used in construction as building stone, paving material, and in the manufacturing of glass and concrete.
Geological facts
Sandstone formations often display distinct cross-bedding layers that reveal ancient wind or water current directions.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, commonly found in desert regions and ancient riverbeds.
