Physical properties

Hardness varies from 6 to 7 on the Mohs scale depending on cementation. Colors range from tan, brown, yellow, red, to grey with a dull or earthy luster.

Formation & geological history

Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, in marine, lake, or desert environments over millions of years.

Uses & applications

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

Geological facts

Sandstone is porous and permeable, making it an excellent natural aquifer for storing groundwater and oil reserves.

Field identification & locations

Easily identified by its visible sand-sized grains and gritty texture; commonly found in riverbeds, deserts, and ancient coastal cliffs worldwide.
