Physical properties

Hardness of 6-7 on Mohs scale depending on cementation, colors range from tan and brown to red and yellow, dull to earthy luster, quartz mineral composition with detrital grains.

Formation & geological history

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

Uses & applications

Widely used as a construction and building material, dimension stone for architecture, paving slabs, and in the manufacturing of glass and silica products.

Geological facts

Sandstone formations often preserve ancient ripple marks and fossil tracks, and famous monuments worldwide like Petra were carved directly into sandstone cliffs.

Field identification & locations

Identified easily by its gritty, sandpaper-like texture and visible sand grains; commonly found in desert regions, canyons, and ancient riverbeds.
