Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in marine, desert, or river environments.
Uses & applications
Widely used in construction as a building material, dimension stone, and for paving or landscaping.
Geological facts
Sandstone formations create some of the world's most iconic geological landmarks, such as Zion National Park and Petra.
