Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in desert, river, or marine environments.
Uses & applications
Widely used in construction as a building material, paving stone, and for manufacturing glass.
Geological facts
Many famous historical monuments and ancient temples around the world were carved directly out of massive sandstone cliffs.
