Physical properties

Hardness varies from 6 to 7 on the Mohs scale depending on cementation. Colors range from tan, brown, yellow, red, to gray due to iron oxides and impurities with a dull luster and clastic texture.

Formation & geological history

Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz and feldspar, in marine, desert, or fluvial environments over millions of years.

Uses & applications

Widely used in construction as a building and paving material, for decorative stonework, and in industry for glassmaking and abrasive grinding wheels.

Geological facts

Sandstone formations frequently serve as excellent aquifers and petroleum reservoirs due to their porous nature. Famous monuments worldwide, including Petra and the White House, are constructed from sandstone.

Field identification & locations

Identify in the field by visible sand-sized grains and a gritty texture resembling sandpaper. Commonly found globally in ancient sedimentary basins, desert regions, and river valleys.
