Physical properties

Hardness 6-7 on Mohs scale depending on cement, colors range from tan and brown to red and grey, dull luster, granular texture composed of quartz and feldspar grains.

Formation & geological history

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

Uses & applications

Widely used in construction as building stone, paving material, and for creating grindstones.

Geological facts

Sandstone is porous and acts as a major reservoir for groundwater and petroleum. Famous monuments like Petra in Jordan are carved directly into sandstone cliffs.

Field identification & locations

Easily identified by its visible sand-grained texture and gritty feel. Common worldwide in sedimentary basins and desert regions.
