Physical properties
Hardness 6-7 on Mohs scale, colors ranging from tan to brown, dull luster, and granular texture with visible sand grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in deserts, rivers, or beaches.
Uses & applications
Commonly used in construction, paving, dimension stone, and for manufacturing glass.
Geological facts
Sandstone is porous, making it an excellent natural aquifer for storing groundwater and oil.
Field identification & locations
Identify by its distinct sandy texture and visible quartz grains; found worldwide in sedimentary basins.
