Physical properties
Hardness of 6-7 (depending on cementation), colors range from tan, brown, yellow, red, to grey, dull/earthy luster, clastic texture with visible sand-sized grains, specific gravity around 2.2-2.8.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz, in environments such as deserts, rivers, beaches, and shallow seas over millions of years.
Uses & applications
Widely used as a construction and building material, dimension stone for paving and flooring, monumental architecture, and in the manufacturing of glass and abrasives.
Geological facts
Sandstone structures can last for centuries, though they are susceptible to weathering depending on the cementing agent holding the quartz grains together.
Field identification & locations
Identified by its gritty texture like sandpaper and visible sand grains. Found worldwide in regions with ancient sedimentary basins, deserts, and coastal deposits.
