Physical properties
Hardness of 6-7 on Mohs scale, tan to brown color, dull luster, granular texture with visible sand grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or marine environments.
Uses & applications
Widely used in construction as a building material, dimension stone, and for paving or landscaping.
Geological facts
Famous monuments worldwide, including Petra and the White House, are constructed from sandstone due to its workability and durability.
Field identification & locations
Identify by its gritty texture like sandpaper and visible sand grains; commonly found globally in sedimentary basins and arid regions.
