Physical properties

Hardness of 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 by the accumulation, compaction, and cementation of mineral particles or rock fragments, mostly quartz and feldspar, in marine, desert, or river environments over millions of years.

Uses & applications

Widely used in construction as a building material, paving stone, and in the manufacture of glass and abrasives.

Geological facts

Sandstone is porous and acts as a major aquifer for groundwater storage as well as a reservoir rock for petroleum and natural gas.

Field identification & locations

Easily identified by its gritty, sandpaper-like texture and visible sand grains. Found worldwide in deserts, riverbeds, and sedimentary mountain ranges.
