Formation & geological history

Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz and feldspar, usually in environments such as deserts, rivers, and beaches over millions of years.

Uses & applications

Used extensively in construction as building stone, paving material, and in the manufacturing of glass and concrete.

Geological facts

Sandstone formations like Zion National Park and Petra are famous for their stunning layers carved by erosion over geological time scales.

Field identification & locations

Easily identified by its gritty, sandpaper-like texture and visible mineral grains. Found worldwide in sedimentary basins and geological strata.
