Formation & geological history

Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz and feldspar, typically in environments like deserts, rivers, and beaches.

Uses & applications

Used widely in construction as building material, paving stones, and in the manufacturing of glass and abrasives.

Geological facts

Sandstone formations can be very durable and form many famous geological landmarks and monuments around the world, such as Petra and parts of the Grand Canyon.

Field identification & locations

Easily identified by its gritty texture and visible sand-sized grains; commonly found in sedimentary basins worldwide.
