Physical properties
Hardness of 6-7 on Mohs scale depending on cementation, predominantly tan to brown or reddish color, dull luster, clastic texture with visible quartz grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz and feldspar, in marine, desert, or river environments.
Uses & applications
Widely used in construction as a building material, dimension stone, paving, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations can act as excellent aquifers for groundwater storage due to their porous nature. Famous monuments worldwide, including Petra in Jordan, are carved directly into sandstone cliffs.
Field identification & locations
Easily identified by its gritty texture resembling sandpaper and visible sand-sized grains. Commonly found in sedimentary basins and geological strata worldwide.
