Physical properties
Hardness of 6-7 on Mohs scale due to quartz content; varies in color from tan, brown, yellow, to red; dull luster; granular texture.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in desert, river, or marine environments.
Uses & applications
Widely used in construction as a building material, dimension stone, and for paving, as well as in the manufacture of glass and abrasives.
Geological facts
Sandstone formations can act as excellent aquifers and petroleum reservoirs due to their porous nature. Famous monuments worldwide, including Petra, are carved directly from sandstone.
Field identification & locations
Identify by its visible sand grains and gritty texture. Found globally in regions with ancient deserts, riverbeds, or shallow marine basins.
